First aid for electrical shock and safety rules 2.1 First aid for electrical shock Do not touch the patient with bare hands until the circuit has been opened. pen the circuit by switching off the line switches. If that is not possible protect yourself with dry material and free the patient from the conductor. 2.1.1 Artificial respiration It is important to start mouth resuscitation at once and to call a doctor immediately. Suggested procedure for mouth to mouth resuscitation method is described in Table 1. 2.1.2 Treatment of burns This treatment should be used after the patient has regained consciousness. It can also be employed while artificial respiration is being applied (in this case there should be at least two persons present). Warning Do not attempt to remove clothing from burnt sections Apply dry gauze on the burns Do not apply ointments or other oily substances.

Installation 6.1 Overview The device can be shipped preinstalled in a cabinet or not. If it is not shipped preinstalled in a cabinet, after unpacking, mechanical installation takes place, followed by electrical connections as described in this document. The device may be installed in any location suitable for electronic communications equipment, provided that the environmental conditions do not exceed the equipment specifications for temperature, humidity, and air quality and that the access to that location is restricted as described below:

access can only be gained by service persons or by users who have been instructed about the reasons for the restrictions applied to the location and about any precautions that be taken;

and access is through the use of a tool or lock and key, or other means of security, and is controlled by the authority responsible for the location 6.1.1 Installation Pre-requisites To ensures the best possible performance and reliability of the described equipment pre-installation planning is required. This includes considering the mounting location of the repeater in relation to input power and antennas. Also to be considered are site environment conditions, the particular mounting method and required tools and equipment. To plan the installation, please pay particular attention to environmental condition at the site, ventilation requirements, and grounding and lightning protection as described in this manual. After that, following the instruction given in this manual:

Unpack and inspect the equipment. Mechanical install the equipment at the site. Make necessary electrical wiring:

- Unit Grounding

- DC input cabling

- Coaxial cables to transmit and receive antennas Perform a post-installation function checkout test of the equipment to verify proper installation. Proceed to customize the repeater parameters per customer specifications (e.g. operating frequency, PL, codes, color code, etc.) SELEX Communications Information contained in this document may not be used, applied or reproduced for any purpose unless agreed by SELEX Communications S.p.A. in writing July 2010 15 6.1.2 Unpack Inspect the equipment for damage immediately after unpacking and make a report of the extent of any damage to the transportation company and to SELEX Communications S.p.A. The following items are packed together:

ECOS-D A2T Radio Base Station DC power cable This manual 6.1.3 Mechanical installation The device is shipped in a box. Upon delivery, the equipment must be removed from the container

(see Unpack section) and transferred to a rack or cabinet. Refer to this manual for all the installation requirements. The device is designed to be fitted in a 19 cabinet using 3 RU of space. M6 screws Customer-supplied cabinets and racks must have mounting rail and hole spacing compatible with EIA Universal 48.3 cm (19 inches) specifications. Cabinets must provide adequate ventilation and must meet the following criteria:

45.0 cm (17.71 inches) deep 48.3 cm (19 inches) wide 13.4 cm (5.25 inches) high SELEX Communications Information contained in this document may not be used, applied or reproduced for any purpose unless agreed by SELEX Communications S.p.A. in writing July 2010 16 Two mounting rails 5 cm (2 inches) from front cabinet with front mounting holes 5.7 cm (2.25 inches) apart (center to center). The front of the device is provided with four holes for M6 screws. This permits to fasten the device to a 19 rack by means of 4 M6 screws. If several devices are installed in a single cabinet, be sure equipment have to be spaced at least by 1/2 RU (2,2 cm, 0,8 inches).to allow for adequate cooling. Cabinets must have a least 15 cm (6 inches) of open space between the air vents and any wall or other cabinets. This allows adequate air flow. When multiple cabinets (each equipped with several repeaters) are installed in an enclosed area, ensure appropriate ventilation and consider air conditioning or other climate control equipment to satisfy the temperature requirements. 6.1.4 Electrical wiring The electrical wiring must be done using appropriate cables thus assuring the equipment responds to the electromagnetic compatibility standards. The cable terminates to flying connectors which have to be connected to the corresponding connectors on the equipment rear panel. The connector of the power cable supplied with the product is the means to disconnect the device from the power source. Position and pinout of the equipment connectors are available in the appropriate section in the following of this document. 6.1.5 Unit grounding The device is equipped with a ground nut located on the rear panel of the device and identified by a label. This nut must be used for a direct connection of the device to the site grounding, even if the device is included in a cabinet. All antenna cables and DC power cabling should be properly grounded and lightning protected. Failure to provide proper lightning protection may result in permanent damage to the radio equipment.

In particular its primary task is to distribute the 13,2 Vdc nominal voltage (Master voltage) and 7 Vdc nominal voltage (Slave voltage). The 7 Vdc Slave voltage is used by all the other modules to power their logic. It is generated by the switch module for direct conversion from the 13,2 Vdc Master voltage. The switch module provides:

ON / OFF of all the modules on the same RBS Protection against Extra Current (short circuit or overload > 22 A 5%) Protection against Extra voltage (maximum input voltage equal to 30 Vdc 5%) Protection against voltages outside the guaranteed operating range [10.8 15.6 Vdc]. Protection against reverse polarity input voltage. Protection against over temperature inside the module itself ( 100 C 1%).

526 MHz). Their time of TX ramp up/down is less than 1200 sec. This makes the module compatible with the stringent demands of digital transmission. Thanks to a microprocessor mounted on board, the module is able to implement the PUFF technology (Powerful Universal Forming Function) for the shaping of transient power in order to obtain compliance with the rapid transient rules of ACP (Adjacent Channel Power). The microprocessor also manages completely the operation of the module: this would remove any calibration procedures. All configuration changes are performed via software. Other main functionalities are:

continuous transmitters operations (100% duty cycle). Output power selectable between two values (Phi and Plo), each of which can be SW set to a nominal value between 10 and 110 Watts. final stage protected against excessive mismatching output power. In the case that VSWR remains above a set threshold (eg ReturnLoss = 5dB) for more than a fixed time, the module is able to send an alert and the output power will not exceed a safety value (eg 10watt). temperature threshold alarm: if the temperature remains above a set value for more than a fixed time, the module is able to send an alert and will ensure that the RF output power will not exceed a predetermined safe value.
