TOPIC MINIMUM INFRASTRUCTURE REQUIREMENTS Hitachi Kokusai Linear Equipamentos Eletrnicos S/A ANNEX I The grounding system, to which Hitachi Kokusai Linear TV transmitter will be attached, must be designed and implemented by trained professionals. An improper grounding system may put at risk, not just the equipment but the life of the professionals working in the shelter. To be considered proper, the grounding must have a resistance of no more than 5 It is important to have isolation between energy stations of the shelter and the TV transmitter, which is achieved with the usage of isolator transformers. Thus is guaranteed that no AC Mains transient coming from the shelter will be passed on to the TV transmitter or vice-versa. Besides, Hitachi Kokusai Linear TV transmitter features switching power supplies that require purely sinusoidal power input, and voltage regulators or no-breaks without isolator transformers have no assurance of a purely sinusoidal outputs. The isolator transformer must also be exclusive to the TV transmitter and its dimensioning must use the same standards employed in the dimensioning of the voltage regulator or no-break, ie, at least 30% higher than the TV transmitters specified consumption (in KVA).

(*) Due to the number of amplifiers not be multiple of 3, the current is not equal to the 3 phases (unbalanced system). The current quoted in the table is more loaded phase to sizing effect of conductors and protection. Said gauge is the minimum recommended for the transmitter in question, if the cable length is large, consider voltage drop in the cable maximum of 5%

The section of the neutral conductor should be the same phase. The section of the ground conductor may be 10% of the phase conductors, not being less than 1mm2. The settings on the green background with table are the recommended settings for each transmitter model. The Atmospheric Discharge Protection System ADPS is comprised by the lightning rod and its accessories. The tower and shelter must be protected against Atmospheric Discharges, through a FRANKLIN lightning rod, dimensioned and installed by the USER, following the criteria defined by NBR 5419

(in its latest version) and including all the station installations within the protection zone defined in the Level I electro-geometric model of rolling spheres. The usage of coaxial protectors is advisable for cables which connect internal and external equipments (antennas, microwave heads, tower converters). These shields are devices featuring gas-sparklers that short-circuit to the ground, any surges discharged in the coaxial cables. Must be within the shelter, close to the equipment and with its ground wire bound in the equipments rack ground.

conditioning system. For project purposes, consider the thermal dissipation specified to the transmitter (BTU/h), the thermal dissipation of the other devices in the shelter, the thermal charge cause by solar incidence and all other thermal charges within the shelter. It is recommended that the internal pressure of the shelter is slightly positive, avoiding the entrance of outside contaminants. According to the transmission power, the internal temperature of the shelter should be:

LOW POWER E-COMPACT TV TRANSMITTERS: from 0 to 35C MEDIUM POWER E-COMPACT TV TRANSMITTERS: from 0 to 30C HIGH POWER E-COMPACT TV TRANSMITTERS: from 0 to 25C In the event of damage caused by inefficient or improper Climate Control Systems within the shelter, will automatically result in the suspension of the warranty terms. I devices must operate in dry environments; this is also achieved by proper Climate Control Systems. In accordance with transmission power, the relative humidity must be:

The relative humidity within the shelter is a solely important factor for best performance and longer lifetime of the equipment. Hitachi Kokusai Linear Y T D M U H LOW POWER E-COMPACT TV TRANSMITTERS: from 0 to 90%

HIGH POWER AND MEDIUM POWER E-COMPACT TV TRANSMITTERS: from 0 to 80%

Manual Rev. 0.0 - April 2016 1-4 Section 1 - Introduction (UHF Digital TV Transmitters) E-Compact - Air Cooling - ATSC - High Power The Architecture of Control for Hitachi Kokusai Linear Transmitters is composed of subcontrol blocks characterized by Control / Exciter Drawers and by Power Drawer. This architecture allows the distribution of control functions. The main control block represents the Control / Exciter Drawer and the sub-control blocks represent the Power Drawers and Telesupervision Drawer (Remote Control Drawer). Each sub-block only reports monitoring information to the main control block, and in some situations the main control block can also transmit commands to the sub-blocks. The Information reported to the control block is displayed on the primary display. The control center of each block and sub-block consists of a microcontroller module of 16-bit and 32-bit, according to its functionality described below:

a)- Main Control Module:

The main control module receives information from the other modules, processes this information for displaying on the LCD and sends it to the system telesupervision. The main module is also responsible for checking abnormal conditions and generate alarms, control of transmitted power levels and general user interface. The main control module can also send commands to the sub-blocks in situations where it is necessary to enable specific protections for sub-blocks and also for the control of information sent and received by the remote supervision system. b)- Power Drawers Control Module The control module sends information to the main module on request. This module has a protection system fully independent of the main control module. The control module is responsible for monitoring the power supplies, the readings of forward and reflected power, cooling system, control of quiescent current according to temperature variation. Alphanumeric User Interface The Control/Exciter drawer has a LCD display in its front panel companied by a keyboard with six keys, which are: ENTER, ESC, LEFT, RIGHT, UP, DOWN. There is also close to these keys a set of indicative LEDs for Control/Exciter drawer alarms. Communication between blocks and sub-blocks The Control / Exciter Drawer uses a communication system called MODBUS. This is a serial communication network operated by the Main Control Module in which each node (sub-block) has its own address. This communication system works with the differential transmission avoiding interference noise.

Section 1 - Introduction (UHF Digital TV Transmitters) E-Compact - Air Cooling - ATSC - High Power 1.4.5 Functional Description of the System 1.4.5.1 ATSC Digital Exciter The exciter is formed by the MOD GV 40153 module drawer more optional (internal GPS, and other software optional). This equipment is responsible for generating the digital TV signal and can perform, among other functions, for controlling the output power and the pre-correction of distortions caused by filtering and amplification stages of a transmitter. Has the following main modules:

1. AC-DC Converter (MOD 4779 FTE 1RU +28V/80W);

2. Ethernet/USB-Host/Device interface board (MOD CIM 3744 DIGI and USB);

3. Keyboard (MOD CIM 3717 TECLADO 1U);

4. Display (MOD CIM 30165 LCD 2x40);

5. MOD VENP 40X40 24V 1U;

6. DC-DC Converter (MOD CIM 30143 PWR 8001 V4);

7. Output Amplifier (MOD 4803 PA 100mW 4001);

8. MOD 4854 EXC DIGI 8001 V4 (MOD 4854);

9. CIM 3832 GPS 8001 (Optional);

10. MOD VENP RADIAL 24V 1U. 1 9 2 3 5 4 10 6 8 7 Figure 1-3 - Internal View The Digital Exciter is responsible for providing an RF signal to excite the amplification stage of the equipment. The exciter input is a BNC connector that may receive either an ASI or SMPTE310M transport stream. The modulation process follows ATSC A/53E recommendation, and is a complex modulation process generating identical phase-modulated orthogonal IF carriers, (I) and (Q) at frequency of 18.833916 MHz. Manual Rev. 0.0 - April 2016 1-8 Section 1 - Introduction (UHF Digital TV Transmitters) E-Compact - Air Cooling - ATSC - High Power Both (I) and (Q) modulated carriers are routed into the IF/UHF up-converter. The local oscillator is a synthesized time-based PLL via an internal VOCXO (Voltage / Temperature Oven Controlled Crystal Oscillator). This oscillator can receive external reference one among 6 possibilities;

(External 1PPS GPS, Internal 1PPS GPS, External 10MHz or Input Transport Stream). The on-channel modulated signal is routed to the RF amplifier, a class A highly linear amplifier with enough head room to accommodate future signal amplitude expansion during the non-linear pre-correction process. The exciter output delivers a 100mW max RF output level, (+20dBm) at the desired UHF channel, driving the RF power amplifiers line-up. The overall RF output power is kept over control via an internal power control loop ALC. The power sensors for direct and reverse power are integrated also on this same PC Board;

allow the power control feature for a several different types and models of transmitters. A sample of the of the RF signal delivery to the load is necessary to be present, so the external loop to control the RF power is closed. (External Power Control Loop). The Master Control Unit (MCU) of the unit is embedded in the exciter. The MCU interacts with all functionality present within the equipment. It further interfaces externally via a keypad and an LCD display. The MCU receives information proceeding from several modules, as the DTV modulator, Up-

Converter, RF amplifiers, RF samples and the administration of passwords. Via keypad it is possible to read and program the power level delivered by the transmitter. Major changes on the transmitter configuration are possible with factory assistance. The Digital Exciter interacts with the HITACHI proprietary software (GUI8001) that performs the implementation of linear and non-linear pre-correction as required; the software also conducts measurements on the demodulated signal, such as MER and power spectrum readings, among others. Figure 1-4 Front view - Digital Exciter ATTENTION: In the event of any changes being required in the settings of the equipment, the Service Department of Hitachi Kokusai Linear should be consulted for further information on the procedures to be adopted.

Equalizer input circuit ASI 1 e 2 Equalize and convert DVB-ASI signal into a differential LVDS signal to the FPGA. Circuit Cable Driver of the outputs ASI 1 e 2 Converts the LVDS signal provided by the FPGA to DVB-ASI electrical standard. The two ASI outputs have the same content. GPS Ublox (Optional) GPS receiver module with input for active antenna (amplified) supplied with +5 V (via coaxial cable) and output PPS (Pulse Per Second) with LVTTL levels. PPS Input and Output Uses components schmitt trigger as interface, has high input impedance (> 1M) and low output impedance (~ 35). Compatible with TTL/ LVTTL level input and LVTTL output. 10MHz Input and output The input circuit is a zero crossing detector with an impedance of 50 and AC coupling. Provides a signal of 10MHz square with LVTTL levels for the FPGA for input between 0 and +10 dBm. The output with an impedance of 50 provides a sinusoidal signal with +8 dBm ~ 700mV DC level to a load 50 or 4Vpp and 1.5 V average for high impedance loads (> 1M). The output signal is a sample of 10MHz from the OCXO, a temperature-controlled oscillator and a frequency range of approximately + / -1.5 ppm or + / - 15Hz. SYSCLK Systems Clock The sysclk circuit is basically composed of two main components, the first is the clock generator

(CI HMC830LP6) that receives the reference of 10MHz and generates a signal of 1377.56643358 MHz (8xSYS_CLK) through the fractional PLL and integrated VCO. The second component is the clock distributor (IC AD9510) which performs a frequency division of 8 and 16 for generating the signs of 172.195804197 MHz (FPGA_CLK, and DAC_CLK and test point SYSCLK) and 86.09790209 MHz (ADC_CLK) respectively. This circuit is configured via SPI interface, by the microcontroller A512 during system startup. The Lock Detect output is used for verification of this circuit. The frequency of the system clock for 6MHz BW is achieved through tithe 8192 * 10 /63. 6 Digital Modulator The ASI reception blocks, remultiplexing, modulation and corrections are described through the languages VHDL and Verilog and synthesized using the Quartus II software. A SOC (System on a Chip) using Nios processor is also present for the execution of the functions of conFiguretion, control and communication of the system using functions described in ANSI C language. The FPGA basically makes the treatment of the input transport stream and modulates this information according to the ATSC standard, generating a complex digital FI (I and Q signals of 16-bit signed complementing 2) with a sampling rate of 86.0979 MSPS. Also performs the linear and non-linear pre-correction, the capture and storage of internal signals and of feedback to implement the tasks of pre-correction and measures. Manual Rev. 0.0 - April 2016 1-12 Section 1 - Introduction (UHF Digital TV Transmitters) E-Compact - Air Cooling - ATSC - High Power Digital-to-Analog Converter and Analog FI generation Composed of the DA converter, reconstruction filter (low pass with fc ~ 50MHz) and FI amplifier. The DA converter operates at 172.0195804 MSPS (interpolation factor equal to 2) and the output amplifier with gain of 7dB has a protection circuit that inhibits its operation during the transient power supply and system startup. The FI signals I and Q (In-phase and Quadrature) are centered on 18,834MHz (obtained by tithe 1024 * 106/63), with an average power of -20 dBm +/- 0.5 dB and intermodulation lower than

-55 dBc at +/-3.25. Local Oscillator The LO circuit is essentially composed of the CI (fractional PLL + VCO) receiving the 10MHz reference and generates a signal corresponding to twice the frequency of the local oscillator

(used by the mixer complex of the up-converter to generate the LO signal with 0 and 90) and also by CI HMC432 which is a frequency divider by 2 (LO signal for monitoring and downconvert). The value of the frequency of the local oscillator can be obtained by the following equation 6MHz BW):

LO(C) = (C-14)*6*106 + 473*106 + 1*106/7 + 1024*106/63 [Hz]

In which C is the desired channel: 14..69 Eg: C=54. LO = (54-14)*6*106 + 473*106 + 1*106/7 + 1024*106/63 = 729,396825 MHz This circuit is configured via SPI interface for A512 microcontroller during system startup. Lock Detect output is used to check this circuit. Up-converter The channel conversion is done by the CI ADL5385, a mixer complex (FI input in quadrature) and input 2xLO (internal generation of LO 0 and 90 ) where the main features are canceling the image frequency (top rate: LO + FI) and reduced leakage of the local oscillator. The cancellation of the image frequency is optimized by adjusting the FI quadrature (amplitude and phase adjustment between I and Q signals). The reduction of LO leakage is maximized by adding a voltage offset in order to compensate for the imbalance present in the DC ports of FI. The minimum expected frequency image rejection is -50dBc and LO leakage is -40dBc. The converted signal in frequency, lower rate (C = LO - FI), is then submitted to the selector circuit low pass filter of 2nd harmonic of four bands, VHF B1 (channels 2-6), VHF B3 (channels 7-13), UHF Low (14-42) and UHF High (43-69), automatically selected according to the channel by the microcontroller A512. The next step is the Voltage-Controlled Variable Gain Amplifier (CIADL5330) which applies a gain proportional to the ALC voltage (Gmin ~= -34 dB to ALC = 0V e Gmx ~= +22 dB to ALC = 1,4V) applied to the pin 24 of the VGA (after resistive divider). The typical maximum output power is 0dBm for an intermodulation smaller than -50 dBc at +/- 3.25 MHz from the center of the channel. Down-converter The circuit down-converter performs the selection of one of the two feedback signals (Before and After Filter or Before and After Filter), performs the beating of this signal with 1xLO using a real passive mixer and gets a FI signal centered at 18.834 MHz. Manual Rev. 0.0 - April 2016 1-13 Section 1 - Introduction (UHF Digital TV Transmitters) E-Compact - Air Cooling - ATSC - High Power The FI signal is then filtered and amplified, this feeds the output stage of AD conversion (Analog to Digital) and the AGC level detector (Automatic Gain Control), which operates in the Truss

(Variable Voltage Controlled Attenuator) of the RF inputs (average power between 0 and +10dBm) in order to maintain the output of FI with an average power of -5dBm + / - 1dB. This signal is available for monitoring via test point connector and is also applied to the drivebuffer that feeds the AD converter, which operates clocked at 86.09790209 MHz and 16 bits resolution. 1.4.5.2 Coaxial Relay (Optional Dual Excitation) The UHF coaxial relay makes the selection of which exciter (A or B) will provide the signal to the passive splitter, which distributes the signal to the power drawers. This switch is controlled by a DC command from the exciter A.The software present on this unit makes the control and selection of which exciter will be transmitting. The exciter which is not selected will remain powered in standby, ready to take control of the equipment. 1.4.5.3 Power Splitter This passive module is a UHF power splitter in quadrature, which is responsible for the clustering of power drawers in parallel configuration. Receives the signal from the exciter and promotes a division 1:N(*5), to excite the UHF amplifiers in the drawer power. Figure 1-7 - Splitter

Each drawer provides 860W from 8 power amplifier in configuration Doherty power amplifier configuration, in this way one obtains a high efficiency amplifier.

(E-Compact ATSC Transmitters) Section 2 Minimum Installation Requirements 2.1 Introduction 2 This section describes the minimum requirements for the E-Compact ATSC transmitters installation, including recommendations about shelter, tower, antennas, cables, grounding, electric network, transient prevention, etc. 2.2 Minimum Requirements 2.2.1 Electric Power 2.2.1.1 Grounding The grounding system to which the Hitachi Kokusai Linear TV transmitter will be connected must be designed and installed by qualified professionals. A deficient grounding system could represent a danger not only for the equipment, but also for people working in the shelter. Moreover, the transmitted signal quality can be remarkably impaired by a deficient grounding system, which usually takes the form of "rames", i.e. vertical bars moving upwards in a television set screen. A satisfactory grounding system should have maximum 5 resistance between the grounding and neutral terminals. An important aspect is that all the devices involved in a transmission system should have the same potential in order to avoid DDP and enable a balanced flow of eventual atmospheric discharges. It must be borne in mind that, if it is necessary to change the chemical characteristics of the soil in order to lower the impedance, a temporary condition would be created (as it would not be the natural local chemistry), which will be naturally absorbed over time. In this case, periodic preventive checking should be made during maintenance activities. 2.2.1.2 Stability The voltages delivered to each phase of the Hitachi Kokusai Linear TV transmitter must be purely sinusoidal and stabilized. For this reason, it is necessary to use voltage stabilizers or stabilized uninterrupted power systems (UPS), since such devices protect the TV transmitter from power surges. It must be kept in mind that input voltage variations more than 15% above the transmitter specification can damage the equipment, and such damages are not covered by the factory guarantee. Moreover, it must be checked the potential difference between the ground and neutral (if any) terminals to be connected to the Hitachi Kokusai Linear TV transmitter. Such potential difference must be maximum 3V. The voltage stabilizer or UPS must be dedicated to the Hitachi Kokusai Linear TV transmitter. The voltage stabilizer or UPS device must be designed for at least 30% above the consumption (in kVA) specified for the TV transmitter. Therefore, in the case of the TV transmitter LD710K, whose maximum consumption is 38 kVA, the voltage stabilizer or UPS device capacity must be 50 kVA. Manual Rev. 0.0 April 2016 2-1 Section 2 - Minimum Installation Requirements

(E-Compact ATSC Transmitters) 2.2.1.3 Insulation It is important to provide suitable electric insulation between the shelter's power points and the Hitachi Kokusai Linear TV transmitter, which can be achieved by means of insulating transformers. This will hinder the passage of any kind of transient from the electric network to the TV transmitter and vice versa. Moreover, the Hitachi Kokusai Linear TV transmitter is fitted with switching power supplies that require a purely sinusoidal input voltage, but output voltages are usually not purely sinusoidal if electronic stabilizers or UPS devices are used without an insulating transformer. The insulating transformer should be dedicated to the Hitachi Kokusai Linear TV transmitter and its capacity should be the same as that adopted for the voltage stabilizers or UPS devices, i.e. 30% above the specified TV transmitter consumption in kVA. The Hitachi Kokusai Linear TV transmitter should not be installed within a radius of 10 meters from the 13-kVA transformer, as it could cause interferences due to the electromagnetic field or sparking in the internal brushes. Recommendations:

1- We recommend that the transmitter "never sees" the electric power directly. 2- We recommend using UPSs online double conversion and / or UPSs online Delta-conversion built with isolation transformer and power factor correction (PFC). Advantages:

- These types of UPSs bring great protection and insulation to the transmitter due to its mode of operation and design.

- The double conversion is due to be converted to AC power and DC to DC voltage is converted back to AC, which eliminates any disturbance in the electric power when converted to DC, thus protecting the transmitter. Important to note that UPS does not necessarily need to have a battery bank, thus minimizing the cost of the final product. This solution is much better than a conventional stabilizer due to double conversion as explained earlier.

- The power factor correction (PFC) in the UPS is necessary to reduce the cost of electricity, it reduces the reactive power (VAr), dimunindo the total power (VA). Importantly, it is not efficient to have a transmitter with power factor correction (PFC) powered by a UPS without PFC, because all the advantage achieved by the transmitter is lost on UPS, not resulting in energy savings. When making this type of connection, you actually had a great load (resistive behavior) to the UPS, but its electric power sees the input of the UPS (without PFC, high consumption). When we have a UPS with power factor correction (PFC), this will present a network for optimal behavior (low reactive power, low consumption) even connected to a transmitter without PFC, ie, it will correct the power factor of all the system.

PHASES and NEUTRAL: 16mm2 or AWG 4 GROUND: In according with standard NBR 5410/2004 2.3 Atmospheric Discharge Protection System 2.3.1 Lightning Arresters The Atmospheric Discharge Protection System comprises the lightning arresters and their elements. The tower and the shelter where the equipment is installed must be protected against atmospheric discharges by means of FRANKLIN-type lightning arresters, which must be designed and installed by the USER in accordance with the criteria set forth by standard NBR 5419 (in its latest version) and in such a way that the whole station is covered by the protection zone as defined by the electrogeometric model of rolling spheres Level I. Manual Rev. 0.1 September 2014 2-4 Section 2 - Minimum Installation Requirements

(E-Compact ATSC Transmitters) All the ferrous parts and accessories that make up the atmospheric discharge protection system must be hot galvanized or plated with a 254-mm coat of copper. The cable length from the lightning arrester up to the flowing pit cannot have any splices and the cable path must be such so as to avoid angles smaller than 90, which could create sparking points. 2.3.2 Cable Protectors It is advisable to use coaxial protectors for the cables that interconnect outdoor equipment

(antennas, microwave heads, tower converters) to indoor equipment. Such protectors are fitted with a gas-filled spark arrester that short-circuits to earth any surge discharged in the coaxial cable. They must be installed in a shelter next to the equipment and the grounding wire must be connected to the grounding connector of the equipment rack. If located in hilltops or areas with many transmission sources, it is recommended to use a Faraday cage or ring to insulate the transmitter from electromagnetic fields and avoid induction interferences. 2.4 Air Conditioning 2.4.1 Temperature For optimum equipment performance and longer life the shelter temperature must be rigorously controlled by means of air conditioning. Taking into consideration the heat dissipation (BTU/

hour) specified for the equipment and the shelter's internal area, the cooling system must be designed in such a way that the incoming air volume is higher than the outgoing air volume in order to avoid negative pressure. The shelter temperature must be determined as a function of the transmission power, as follows:

TV TRANSMITTERS UP TO 250W: from 0 to 35C TV TRANSMITTERS FROM 500 TO 1kW: from 0 to 30C TV TRANSMITTERS ABOVE 2kW: from 0 to 25C If a Hitachi Kokusai Linear equipment is damaged due to the lack or inefficiency of the air conditioning system, it shall NOT be covered by the guarantee. 2.4.2 Humidity The relative air humidity inside the shelter is also a very important factor to improve the equipment performance and extend its life. Hitachi Kokusai Linear equipment must operate in a dry environment, which can be ensured by means of a suitable air conditioning system. Depending on the transmission power, the shelter's relative humidity should be as follows:

TV TRANSMITTERS UP TO 500W: from 0 to 90%

TV TRANSMITTERS ABOVE 1kW: from 0 to 80%

Manual Rev. 0.1 September 2014 2-5 Section 2 - Minimum Installation Requirements

(E-Compact ATSC Transmitters) 2.4.3 Cooling The air conditioning system should always be operated in the "recirculation" mode, with the room temperature being reduced without outside air coming in. For improved cooling system performance, the air conditioner should be installed in series with the transmitter's cooling cycle. I.e., the air conditioner's outgoing flow must be directed to the front part of Hitachi Kokusai Linear TV transmitter. The transmitter's installation layout should contemplate a free space around the transmitter for higher cooling efficiency and access for maintenance. Refer to the table below for details:

Transmitter Free internal area EC701HP EC702HP EC703HP EC704HP EC706HP EC708HP 16,0m Note: If the transmitter is installed in a rack, the transmitter front and rear must be entirely unobstructed. Manual Rev. 0.1 September 2014 2-6 Section 3 - Installation (ATSC EC702HP Transmitter) Section 3 Installation 3.1 Introduction 3 This section provides general information for planning the installation of the EC702HP transmitter, such as recommendations regarding Shelter, Tower, Antennas, Cables, Grounding, Power Line, Prevention against Transients, etc. 3.2 Inspection The package and the equipment must be inspected upon delivery in order to detect eventual visible damages. If there are signs of violation or physical damage (which points to transportation problems), the corresponding evidences should be described in the delivery documentation provided by the transport company. Such notice would be used to establish the responsibilities for the product integrity. Hitachi Kokusai Linear carries out operating tests at the factory on every transmitter in order to ensure proper operation after delivery to the user. Nevertheless, if the equipment does not operate after the start-up and there is no evidence of transportation damage, it might be necessary to send the equipment back to the factory for repair or replacement. In such a case, please get in contact with Hitachi Kokusai Linear Equipamentos Eletrnicos S/A's Technical Support Department. 3.3 Installation Recommendations 3.3.1 Preventive Protection Voltage transients with a duration of micro and nano-seconds are a constant challenge for the solid state circuits. The downtime and the equipment maintenance make the preventive protection the best warranty against these surges.This protection can be in many forms, from isolation transformers and no-breaks to the more efficient but more expensive AC Voltage Protectors. Since lightning is the most common cause of transients, AC Voltage Protectors are the best choice. An efficient AC Voltage Protection must be able to dissipate the energy to a low voltage, sufficient to guarantee the protection of the eletronic components. The protection must be always placed transversely to the AC line, even during blackout periods.In addition, it must be immediately and automatically turned-on and ready in case of repeated transients. Manual Rev. 0.0 - April 2016 3-1 Section 3 - Installation (ATSC EC702HP Transmitter) 3.3.2 Tower For the installation of the TV transmission and reception system, the tower must be made with hot-dip galvanized steel. A lightning protection system should be installed in the tower as well as nocturnal beacons bulbs with red glass. The following information about the tower must be obtained:

(a) It must be provided of special insulator supports for descent of cordage of lightning rod, with a space of 1,5m maximum between them.

(b) There must be a lightning signaling system in every 20m along the tower.

(c) It must be painted with orange and white stripes in every 2m with a special paint that complies with local regulations.

(d) It must endure winds of up to 150 Km/h. In a retransmission station the tower is the highest and therefore, the most vulnerable device to be hit by lightning and because of it, the tower is used as a part of the protection system.The lightning protection device used in these cases is called lightning rod and has the function of guiding the electrical discharge safely, avoiding other parts of the system to be hit and damaged by it. The use of a lightning rod is MANDATORY. The project and installation of grounding and lightning protection systems must be performed by specialized companies. Eventual damage to the equipment caused by missing or malfunctioning of the arrester is not covered by warranty. 3.3.3 Fastening of cables, antennas and connectors Please observe the following items when installing antennas:

Direction of Antennas and Aperture Angles Use a pocket compass when directing the antenna.Use a field strength meter for the fine adjustment of the recepton antenna. Height It mainly depends on the receiving signal and the transmission conditions (obstructions, attended area, etc). Its very important to verify how far the antenna is from the lightning protection device, since the antenna must stay inside its cone protection. Manual Rev. 0.0 - April 2016 3-2 Section 3 - Installation (ATSC EC702HP Transmitter) Distance between the Rx and Tx Antennas They should be placed as far as possible from each other in order to isolate the transmitted signal from the received signal. Polarization It is very important to verify the polarization of the received signal, which can be vertical, horizontal or circular. Phasing When receiving a signal with vertical polarization, the system must be mounted vertically, otherwise the gain of the antenna will be drastically reduced, likewise in case of a signal with horizontal polarization. To receive a signal with circular polarization with a non-circular antenna, the system can be mounted either vertically or horizontally. Stacking antennas When using this system, the distance between them depends on the kinds of antenna used and the kind of stacking used. This must be studied thoroughly in order to obtain the best solution for each case. Cables and Connectors All cables must be carefully installed in order not to be twisted during the installation process. When using 7/8" or 1/2" cables, please pay attention to their bending that must not be made in spaces smaller than 80cm. The cables can't force the connectors in the Input/Output of the equipment. The entry holes for the cables in the shelter must be done in a way to avoid the water that runs along them to get inside. Follow the manufacturer 's instructions when assembling them. All splices done outside the shelter must be isolated with a special plastic tape and/or a plastic insulation material. Avoid using silicon to coat the isolation made with auto-fusion tape. It has been verified that the silicon chemical characteristics may provoke the drying of the auto-fusion tape. Manual Rev. 0.0 - April 2016 3-3 Section 3 - Installation (ATSC EC702HP Transmitter) 3.3.4 Equipment Installation Indoors Small equipments must be placed on a table in a way to provide easy access from all sides and be at least one meter far from the walls. Do not place anything on the top of the equipment in order not to compromise its natural ventilation. The ventilation system equipments must be placed directly on the shelter's floor as long as it is flat and they must be placed at least one meter far from the walls. Some of these air outlet must be connected to the outside of the shelter through PVC tubing. The AC cable has two terminations to be used exclusively in the equipment. 3.3.5 Equipment Grounding The grounding has to be made separately from the power supply, with a rig and a grounding terminal that come with the equipment. Normally, the retransmission sites are located in the highest spot of the chosen location, what makes them more vulnerable to lightning strikes. These discharges carry a great amount of electric energy, putting at risk not only the antenna and its structure but also the equipments in the shelters. In order to minimize this effect and guarantee their protection and continuous service during thunderstorms with lightning, the use of a reliable grounding system is paramount. Lightning is a transient, high-current eletric discharge that happens between the ground and the clouds therefore the most important part of a lightning protection system are the parts that are on the ground.In order to maintain the low impedance of the technical grouding system, it must be carefully executed in a way that the electric field energy is drained away without affecting the equipment.In order to define a system, the characteristics of the soil resistivity must be taken into consideration. To dertermine the behavior of the soil capacity to drain the currents, its resistivity has to be measured. For an adequate protectionm this value should not exceed 5 , being zero the ideal value Generally, the grounding method used for TV retransmitters is a system with a single vertical electrode made with copper measuring 2.5 meters or more. In case the conditions and characteristics of the soil are of high resistivity or high incidence of lightning discharges, the grounding system must be thoroughly analyzed. It is very important to notice that the grounding systems of the equipments and the lightning rod are independent and should never be connected to each other. A poorly elaborated grounding system can cause damages to the equipment that won't be covered by the warranty. Manual Rev. 0.0 - April 2016 3-4 Section 3 - Installation (ATSC EC702HP Transmitter) 3.3.6 Electric Installation Grounding The shelter installations receive power through an aerial power line. Moreover, because of it, the lightning discharges that might hit the power lines generate power surges that can reach the shelter and consequently the equipments. To protect the equipments against eventual power surges, we recommend the use of gas filled surge protectors, after an isolation transformer with electrostatic shield. When installing the grounding system, please observe the following items:

Connect all equipment carcasses to the grounding system using the grounding rig that comes with them. Connect the gate and all the wires from the fence to the grounding system. Connect the neutral wire from the public power line to the grounding system. Connect the rig from the lightning rod to the grounding system with the shortest connection possible avoiding cable splices. The towers structure must also be connected to the grounding system. Use porcelain isolators to insulate the lightning rod rig. 3.3.7 Power Supply Before plugging the equipment to the power supply, verify the voltage in the outlet to make sure that is correct.If its variation is greater than 10%, it is necessary to use a power stabilizer to correct the voltage. The power provided by the stabilizer must be at least 30% greater than the consumption of the equipment Manual Rev. 0.0 - April 2016 3-5 Section 3 - Installation (ATSC EC702HP Transmitter) 3.4 Mechanical Drawings This section shows the mechanical drawings relative to the external structure of the equipment, including location of drawers, panels, etc. 3.4.1 Front View EXCITER A EXCITER B ETHERNET SWITCH*

Manual Rev. 0.0 - April 2016 3-42 Section 3 - Installation (ATSC EC702HP Transmitter) REMARK Interlock is a protection device that energizes the contactor from a external command. The contactors of feeding of the power drawers, will only be engaged if the interlock is short circuited or if the external element (dummy load) provide a dry contact to the transmitter. In the case of using a dummy load, the interlock functions as protection for it, since this type of loading will be damaged if a power be applied without proper cooling. If there is no use for the interlock in the equipment, a wire must short circuit the connector. ATTENTION Prior to energizing the transmitter, one must make sure that the circuit breaker and the power switch (ON / OFF) are switched off or disabled. C- Rigid Line / Filter / Antenna Connect the curves and rigid lines as required to interconnect the equipment to the filter and the filter to the antenna. ATTENTION It is mandatory to use INNERS in all the connections. The connection screws must be properly tightened.

Screen [2100]. The ALC voltage is directly proportional to the RF power at the transmitter output. Manual Rev. 0.0 - April 2016 4-6 Section 4 - Initial Activation (ATSC Transmitters) NOTE: If an alarm occurs during the power increase, it is advisable to reset the output power of the transmitter to seek the solution. If necessary contact the Service Department of Hitachi Kokusai Linear Electronic Equipments S / A. Check if there is any abnormal or differential heating, in the connection joints between the transmitter, filter, antenna and adders imbalance load. If there is any abnormal warming in an isolated way, this may indicate some flaw or imperfection in that connection. This must be checked before continuing on increasing the transmitter power. NOTE: When operating under normal conditions, the modules located at the transmitters rear may reach up to 55C. This is due to the fan speed control, which is responsible for keeping the transistors temperature at 60C (it can be set from 50 to 60 in the EQP Setup Menu, it is factory set to 60 and the optimization of this temperature is done during activation by varying according to the efficiency of the transmitter and the ambient temperature). See item 3.4.5 PA Temperature Control. As well as the presence of aluminum heatsinks and high thermal dissipation pallets. All passive devices are located at the rear panel and operate within the temperature ranges recommended by the manufacturer. Check the current reading and the drawer module temperature, observing whether there is any abnormality present. If there is any, check the connections of RF and if the problem persists, contact the Hitachi Kokusai Linear Customer Service. Repeat the previous steps for programming 25%, 50%, 75% and 100% of the rated power. Between steps, consider a minimum of fifteen (15) minutes. Enable / disable the automatic shutdown of the equipment by the absence of ASI signal. Sequence 3 screens to enable automatic reconnection of the equipment by the absence / presence of the ASI signal.

After this, only the LED will remain lit named POWER ON. Main Menu System Alarms / Log Clear Alarm Log. 4.3 Possible operations with the Transmitter in Operation A- Power Changing POWER SETUP ([1100]) The alteration of the transmitter power is something possible and accessible to the customer through the screen POWER SETUP ([1100]) by software navigation Menu, in the digital display, according to instructions given in the section 5. B- Transmitters Pre-Correction The linear and non-linear pre-corrections are previously applied to the transmitter in the factory. C- Enable and disable the linearization Non-Linear Pre-Correction - You can enable or disable the non-linear pre-correction by the front panel. Linear Pre-Correction - You can enable or disable the linear pre-correction by the front panel. NOTE: At the time that the linear or non-linear preset is enabled or disabled, the transmitter power is reduced to 25% of programmed power and returns to 100% a few seconds later. 4.3.1 Communication A- Via Ethernet This equipment has a W eb Page server accessed by the Ethernet port located on the front panel of the digital exciter, which has all the functionality of the keyboard interface + display. Eg, settings, measurements, alarms, etc.This interface can be used for remote management. Manual Rev. 0.0 - April 2016 4-9 Section 4 - Initial Activation (ATSC Transmitters) B- Via USB with the Digital Exciter The communication of the digital exciter via USB port, is only possible with the use of the software GUI8001 (optional). 4.3.2 Serial terminal Emulators The Power Drawer can be configured using the serial terminal emulators. 4.3.3 Forbidden operations There are transmitter parameters which are configured at the factory, parameters defined on the purchase of the transmitter, which are not available to change.

- Canal

- Equipment model There are other parameters that are configured in the factory, but allow changes in their values by using a password. The careful use of the password is to prevent unauthorized access that can cause the appearance of a reflected power at the transmitter and consecutively decreasing the value of the output power of the transmitter due to the protective action of the same.

- L.O. Null

- Frequency image adjustment 4.3.4 Safeguards A Potncia refletida If the incidence of reflected power at the transmitter due to any external or internal factor occurs, this can be viewed on the measurement screen (MEASUREMENTS [2000]) by the softwares navigation Menu, in the digital display, according to instructions given in the Operation Section of the Digital Control System. If the value of the reflected power exceeds the value of 2%* of rated power, the control will immediately signal this fact by lighting the LED current alarm on the front panel of the digital exciter, will provide, on the current alarm screen, and this will trigger the routine protection against reflected power. This will gradually decrease the value of the forward power until the amount of power reflected returns to less than 2% of rated output. At this time, the software returns to gradually increase the value of forward power, foreseeing the possible disappearance of the reflected power. Thus, the equipment will be oscillating between increase and decrease of the direct power around the power value that provides a reflected power of 2% of rated power, always seeking the return to the rated power of equipment. The 2% value to generate the reflected power alarm is fixed, ie the alarm will always occur when the reflected power is 2% of the nominal power of the EQP. Already the reflected value that will make the EQP reduce direct power is configurable from 2 to 5%. To change this value, go to Setup Menu-> Alarms Mask-> Reflected and change as needed.

* Approximately Manual Rev. 0.0 - April 2016 4-10 Section 4 - Initial Activation (ATSC Transmitters) B Super-Excitement If an excessive increase in the value of the excitation signal level occurs, the control, through the ALC, will interact with the excitement, to maintain a constant output power in its rated value. C Variations in the network Each piece of equipment has its own independent power supply, all of which have equal protection features.

- Protection against short circuit

- Surge Protection Basically, the surge protection on the network is performed by inserting the varistors between phases and between phase and earth, thus absorbing peak voltage, not allowing them to damage the power source. Protection against short-circuit is carried out by monitoring the current in the output of the power source. If the current exceeds a pre-set reference value, it will understand that the source output is shorted and should be disabled through the shutdown pin. 4.3.5 Transistor Temperature Setting The default temperature value of the transistor is 60 (140 F), factory set, the hottest transistor will be the reference. The temperature can be set between 50 and 60 in the Setup Menu "PA Temperature Control" (Setup Menu [1M00]). This setting can be changed according to ambient temperature and transmitter efficiency. You can change this setting by following the procedure below:

- With the transmitter in the operating power for at least 30 minutes, access the web page of the transmitter or the USB interface of the power drawer and check the rotation of the fans. Fan rotation should be between 2000rpm and 7000rpm.

- After checking all fans of all drawers and if the highest rotation is below 5500rpm, the control temperature can be reduced, it is advisable to reduce in steps of 2 degrees.

- Set the transistor temperature in the "PA Temperature Control" Setup Menu. Once the fan speed is set, you should wait a few minutes until the transistor temperature stabilizes at the set value, then check the fan speed again, operation will be between 5500rpm and 6000rpm. 4.4 Automatic Power reduction Table In case of any defect or failure to communicate in one or more Power Drawers, the equipment will continue running, but on condition of power reduction. The reduction table of each equipment of the E-Compact series is calculated according to the following formula:

In this condition, the equipment will operate with a power reduction alarm and with other alarms that identifiy which of the drawers are not operating and the reason of it. The EC701HP transmitter uses reduction table for modules. Below the formula for calculating table:
