Issue 10 (2015-12-30) Huawei Proprietary and Confidential Copyright Huawei Technologies Co., Ltd. 14 RRU3268 Installation Guide 3 Information About the Installation Requirements for the Installation Scenarios Application scenarios:
To ensure proper heat dissipation of the RRU, the following requirements must be met:
l The RRU cannot be installed in an enclosed cabinet without a cooling system. l The RRU cannot be installed in an enclosed camouflage box. l The RRU cannot be installed in an enclosed equipment room without a cooling system. l When multiple RRUs are installed in centralized mode, the minimum clearance requirements must be met. For details about the minimum clearance requirements, see 3.5.2 Clearances for Three or More RRUs and 3.5.3 Installation Spacing Between RRUs. l RRU mounting kits in assembled installation mode are not allowed in indoor scenarios. NOTICE If the RRU is improperly installed, heat dissipation of the RRU deteriorates and the RRU may not work properly, as shown in Figure 3-5. Figure 3-5 Improperly installed RRUs Method of installation:
l The installation supports' specifications described in this document are only based on the exterior and dimensions of the mounting kits. Before installing equipment, assess the strength and reliability of the installation support to determine whether it can bear the weight of the equipment. l To ensure the heat dissipation of the RRU and waterproofing of the ports at the bottom of the RRU, the vertical deviation angle of an RRU must be less than or equal to 10 degrees, as shown in Figure 3-6. l On a tower, an RRU can be installed on a pole, angle steel, or U-steel. The side-mounted installation mode (one side instead of the rear of an RRU is mounted on the support) is recommended for RRUs on the main pole secured on a tower. This installation mode Issue 10 (2015-12-30) Huawei Proprietary and Confidential Copyright Huawei Technologies Co., Ltd. 15 RRU3268 Installation Guide 3 Information About the Installation allows multiple RRUs to be installed next to each other at the same level on a pole. When the horizontal distance between the main and auxiliary poles on a tower is equal to or greater than 810 mm (23.62 in.), the side-mounted mode is recommended for installing RRUs on the auxiliary pole to meet the minimum clearance requirements. Otherwise, the standard mode is recommended for installing RRUs on the auxiliary pole. Figure 3-6 Requirements for the vertical deviation angle of an RRU

Issue 10 (2015-12-30) Huawei Proprietary and Confidential Copyright Huawei Technologies Co., Ltd. 85 RRU3268 Installation Guide 9 Installing RRU Cables 9.1 Cabling Requirements Cables must be laid out according to the specified cabling requirements to prevent signal interference. NOTE If a cable listed below is not required, skip the cabling requirements of the cable. General Cabling Requirements Bending radius requirements l The bending radius of a 7/8'' feeder must be greater than 250 mm (9.84 in.), and the bending radius of a 5/4'' feeder must be greater than 380 mm (14.96 in.). l The bending radius of a 1/4'' jumper must be greater than 35 mm (1.38 in.). The bending radius of a super-flexible 1/2'' jumper must be greater than 50 mm (1.97 in.), and the bending radius of an ordinary 1/2'' jumper must be greater than 127 mm (5 in.). l The bending radius of a power cable or PGND cable must be at least three times its diameter. l The bending radius of a fiber optic cable is at least 20 times of its diameter, and the bending radius of a breakout cable is at least 30 mm (1.18 in.). l The bending radius of an E1/T1 cable must be at least three times its diameter. l The bending radius of a signal cable must be at least five times its diameter. Cable binding requirements l Cables of the same type must be bound together. l Different types of cables must be separately laid out and bound, with a minimum distance of 30 mm (1.18 in.) from each other. l The cables must be bound tightly and neatly. The sheaths of the cables must not be damaged. l The cable ties must face the same direction, and those at the same horizontal line must be in a straight line. l The excess of the indoor cable ties is cut off. The excess of 5 mm (0.197 in.) of the outdoor cable ties is reserved, and the cut surfaces are smooth without sharp edges. l After cables are installed, labels or nameplates must be attached to the cables at their ends, curves, and interconnection positions. Security requirements l When routing cables, avoid sharp objects, for example sharp edges on the wall. If necessary, use tubes to protect the cables. l When routing cables, keep the cables away from heat sources and use heat insulation materials to insulate the cables from the heat sources. l Reserve a proper distance (0.1 m or 3.937 in. is recommended) between equipment and cables especially at the cable curves to protect the cables and equipment. Indoor cabling requirements l Route each cable into the room through the feeder window. Issue 10 (2015-12-30) Huawei Proprietary and Confidential Copyright Huawei Technologies Co., Ltd. 86 RRU3268 Installation Guide 9 Installing RRU Cables l Reserve drip loops for all cables outside the feeder window before routing them into the room. Ensure that the radiuses of the drip loops are greater than or equal to the minimum bending radiuses of the cables. l When routing a cable into the room, ensure that a person is assisting you in the room. l Apply waterproof treatment to the feeder window. Outdoor Cabling Requirements l After being connected to a ground clip on power cables, a ground cable must be routed downwards to prevent water from entering the equipment to which the power cables connect. l Protect outdoor cables against potential damage. For example, put the cables through tubes. l The cables to be protected include AC power cables, transmission cables, and cables laid out underground. l When routing cables through tubes on the ground below the cabinet, put a 30 mm to 50 mm (1.18 in. to 1.97 in.) length of the tubes into the base of the cabinet but do not put the tubes into the cabinet. Use waterproof tape or waterproof silicon gel to block both ends of the tubes and use sheet metal tabs to secure the tubes to the cable holes in the base. l When routing cables through tubes along a metal cable trough below the cabinet, do not put the tubes into the base of the cabinet but cover the cable trough and connect the tubes to the cable holes in the base. l When routing RRU cables, ensure that the highest positions of the routes of all RRU cables (except RF cables and AISG cables) must be lower than the bottom of the RRU. l Use clips to secure cables outdoors. For the method of installing a clip, see the installation guide delivered with the clip. l Arrange cables neatly along the routing direction and use clips to secure the cables. l Determine the positions where the clips are installed according to the actual situation. For example, 7/8" feeders are secured with clips at an interval of 1.5 m to 2 m (4.92 ft to 6.56 ft), CPRI fiber optic cables and power cables are secured with clips at an interval of 1 m to 1.5 m (3.28 ft to 4.92 ft). Ensure that the clips are evenly spaced and in the same direction. l When fastening cables with a clip, ensure that the cables are aligned neatly and are routed through the holes in the clip. Do not stretch the cables too tightly. NOTE There are two types of clips: 3-hole clip and 6-hole clip, which are described as follows:
l l A 3-hole clip is shown by illustration a in the following figure. It is often used to fasten feeders. A 6-hole clip is shown by illustration b in the following figure. It is often used to fasten power cables and CPRI fiber optic cables.

The cabling activities of fiber optic cables are allowed only when qualified personnel and communication facilities are available. l Do not circle and twist cables. Issue 10 (2015-12-30) Huawei Proprietary and Confidential Copyright Huawei Technologies Co., Ltd. 89 RRU3268 Installation Guide 9 Installing RRU Cables l After routing a DC power cable onto the platform on a tower, route it along the shortest path to the rails surrounding the platform, and route it along the inside of the rails. l After routing a DC power cable close to the equipment on a tower, use clips to secure the power cable onto a pole or the rails surrounding the platform. Ensure that there is no excessively long distance between the equipment and the position where the power cable is secured. Cabling of PGND cables l PGND cables for a base station must be connected to the same group of ground bars. l PGND cables must be buried in the ground or routed indoors. l The external conductor of the coaxial wire and the shield layer of the shielded cable must have proper electrical contact with the metal surface of the equipment to which they are connected. l PGND cables and signal cables must be installed separately. A certain distance must be reserved between them to prevent interference from each other. l Switches or fuses must not be installed on the PGND cables. l Other devices must not be used for electrical connections of the PGND cables. l All the metal parts in the housing of the equipment must be reliably connected to the ground terminal. Cabling of E1 cables l E1 cables must not cross power cables, PGND cables, or RF cables when laid out. If transmission cables are laid out with power cables, PGND cables, or RF cables in parallel, the spacing between them must be greater than 30 mm (1.18 in.). l E1 cables are lined up straight and bound neatly with cable ties. l Sufficient slack is provided for E1 cables at turns. l E1 cables must not be pressed by the door of the cabinet when routed, as shown in the following figure.

Otherwise, tipping or falling cabinets may cause bodily injury and equipment damage. Leave proper clearance around the equipment. Make sure an enclosed cabinet is adequately ventilated. 1.2.2 Outdoor Installation Outdoor Installation Requirements Safety Information Do not work on outdoor equipment and cables in lightning, rainy, snowy, windy (wind force > 6) and other adverse weather conditions. Ensure that the enclosure is class IP54 or higher. Comply with all related local regulations. Set up signs at the site to indicate a dangerous restricted area inaccessible to unauthorized personnel. The scaffolding, platforms, and workbench must pass safety checks to ensure structural integrity. Do not overload the scaffolding. Avoid simultaneous work at heights and on the ground. If such situations cannot be avoided, erect a special protective shed or other protective measures between the height and ground, and clear piles of tools and property from the area. Do not loiter in the work area. Any violations must be promptly pointed out by the site manager or safety supervisor and prompted for correction. If the problem persists, the personnel involved risks suspension that is regarded as absenteeism. Operators are responsible for accidents resulting from violation of safety regulations or failure to make timely correction. Supervisors also bear responsibility. Installation at Heights Work performed 2 m (6.56 ft.) above the ground is regarded as work at heights. Work at heights, comply with related local regulations. Only skilled and trained personnel are allowed to work at heights. Stop such work in any of the following conditions: adverse weather, wet steel tubes, and other risky situations. Resume work only after a Huawei safety director and related technical personnel have checked all the equipment. The ladder used in work at heights must be intact and skid-resistant to ensure safe climbing. The recommended angle between the ladder and the ground is 75. When using a step ladder, the rope must be strong and the ladder must be supported. Place guardrails and warning signs around protrusions and holes to avoid accidents. Safety Information Before proceeding, carefully check climbing and safety tools, such as the safety helmet, safety belt, ladder, springboard, scaffolding, and hoisting equipment. If any tool does not meet requirements, fix or replace it immediately, or postpone the work. Wear proper safety PPE and a helmet as well as a belt or waist rope secured to a robust support. Do not tie the belt or waist rope to an unstable object or metal with sharp edges. A fastener that detaches may cause a falling accident. Avoid dropping machinery and tools that may cause injury. Transport all objects from or to the ground level by a strong rope, basket, elevated vehicle, or crane instead of throwing them. Do not pile up scaffolding, materials, and other debris on the ground under the work area at heights that cause traffic obstructions. After completion, disassemble the scaffolding layer by layer from top to bottom. Do not disassemble top and bottom layers at the same time. When disassembling a part, prevent the collapse of other parts. 1.3 Electrical Safety Grounding Ensure that the protection ground is reliably grounded in accordance with local building distribution specifications. For equipment requiring grounding, always connect the protection ground first and disconnect it last when installing the equipment. For the equipment using a socket with an earthing terminal, ensure that the earthing terminal is correctly grounded. The device must be connected permanently to the protection ground before an operation. The cross-sectional area of the protective ground conductor must be at least 1mm2. AC/DC Operation Do not contact the power system supply directly or indirectly through damp material. The hazardous voltage may cause electric shock. Improper operation may cause accidents such as fire and electric shock. This device relies on the building's installed overcurrent protection from short circuits. Ensure that a fuse or circuit breaker no larger than 80 V, 30 A is used on the phase conductors that include all current-carrying conductors. Check that all specifications are compatible before equipment installation. If the power input of the equipment is permanent, ensure that an easy-to access disconnection device is installed on the exterior of the equipment. Safety Information Use AC-supplied models for TN, TT power systems. For DC-supplied models, use reinforced insulation or double insulation to isolate the DC source from the AC mains supply. Before connecting equipment, disconnect the corresponding external-equipment circuit breaker. Before connecting the load (electrical equipment) or battery cable, verify that the input voltage is within the rated voltage range of the equipment. Before connecting the load (electrical equipment) or battery cable, check the cable and terminal polarities to avoid reverse connection. Before powering on, verify that equipment electrical connections are correct. If the device has more than one power supply, disconnect all of them when powering off the device. Cabling Requirements Only cut the insulation layer at the wiring part when preparing the power cable at the site. Doing so prevents accidents and fire from short circuit. High-temperature environments may cause wear and tear on the insulation layer. Leave sufficient clearance between the cable and power busbar, current shunt, fuse, heat sink and other heating devices. Bind the signal cable and the strong current or high-voltage cable separately. Cables provided by the customer must comply with local cable regulations. Do not route any cable through the air exhaust vent in the cabinet. If cables have been stored in an ambient temperature below 0 C (32 F), move the cables to a room-temperature environment at least 24 hours before installation TNV Circuits To avoid electric shocks, do not connect the safety extra-low voltage (SELV) circuit to the telecommunication network voltage (TNV) circuit. Do not tamper the cable connected to the outdoor signal port in adverse weather conditions. To reduce the risk of fire, use only a No. 26 AWG or larger telecommunication line cord. ESD Requirements To avoid component damage caused by electrostatic buildup, wear ESD gloves or an ESD wrist strap and properly ground the other end of the ESD wrist strap before touching a circuit board. Hold the board by its component-free edge and do not touch chips with your hands. Place removed boards in ESD packaging for storage or transportation. 1.4 Battery Safety The safety information in this document is a reminder and for reference only. Read the detailed safety information in the manufacturer instructions before battery installation, operation, and maintenance. Safety Information Before installing batteries, ensure that you understand the safety requirements and correct connection procedures. 1.4.1 Basic Requirements Do not expose batteries to high temperatures or heat sources such as sunlight, heaters, microwave ovens, ovens and water heaters. Overheating batteries may explode. Do not disassemble or refit batteries, insert foreign objects, or submerge into water or other liquid. Leakage, overheating, fire, or explosion may occur. Wear goggles, rubber gloves, and protective clothing during installation and maintenance to avoid injury caused by electrolyte spillage. Avoid contact with eyes and skin in case of battery leakage. Rinse any accidentally exposed area with water and seek immediate medical treatment. Transport batteries in their specified positions. Do not tilt or turn them upside down. Disconnect the circuit before battery installation and maintenance. Use the same or equivalent type of battery to replace faulty ones. Incorrectly replaced batteries may explode. Do not connect metallic conductors to battery terminals or contact battery endpoints. Battery short circuit or overheating may occur and cause injury. Follow local regulations for battery disposal. Do not dispose of batteries as domestic waste. Incorrectly disposed batteries may explode. Do not drop, squeeze or puncture batteries. Avoid strong external pressure that may cause internal short circuit and overheating. Do not use damaged batteries. Keep children and pets away from batteries to avoid injury or battery explosion. 1.4.2 Requirements for Rechargeable Batteries If discoloration, deformation, overheating, or any other abnormality occurs, replace the batteries before continuing with usage, charging or storage. Tighten battery cables or copper bars using the torque specified in the battery documentation. Insecure connection of battery bolts may cause excessive voltage drop or even overcurrent leading to battery overheating. Short Circuit Protection Battery short circuit will produce a strong spike in current and release a large amount of heat energy that may cause bodily injury and property damage. Disconnect running batteries before other operations whenever possible. Flammable Gas Protection Safety Information Do not use unsealed lead-acid batteries. Lead-acid batteries should be positioned and secured horizontally for normal hydrogen discharge to avoid combustion or equipment corrosion. Improper usage of lead-acid batteries will cause the release of flammable gas. Ensure that batteries are kept in a well-ventilated area and take preventive measures against fire. Leakage Protection Battery overheating causes deformation, damage, and electrolyte spillage. If the battery temperature exceeds 60 C (140 F), check for and promptly handle any leakage. Use a neutralizing liquid to absorb any electrolyte spillage. Exercise caution when handling the leaking battery because the electrolyte can cause injury. When removing or moving the battery with spilled electrolyte, be careful with the electrolyte that can bring potential injury. If any electrolyte spills, use NaHCO3 or Na2CO3 to neutralize and absorb it. Battery Discharge Protection After batteries are installed, ensure that the fuse or circuit breaker is disconnected before powering on the system. This avoids battery damage caused by power discharge in case of long-term power-off. 1.4.3 Requirements for Non-Rechargeable Batteries If discoloration, deformation, overheating, or any other abnormality occurs, replace the batteries before continuing with usage, charging or storage. Do not attempt to replace non-removable, built-in batteries. Doing so may damage the batteries or the equipment. Batteries must be replaced by an authorized service center. Do not throw batteries into fire. 1.5 Radiation Safety 1.5.1 Electromagnetic Field Exposure Safety Information Strong electromagnetic signals harm human health. Equipment like radio transmitter or associated products must be handled with consideration of exposure to radio electromagnetic fields (electromagnetic radiation). Working with high-voltage equipment or facilities risks exposure to high-frequency electromagnetic fields. Radio service carriers and other users must comply with local laws and regulations when deploying wireless base station transceivers, or other equipment or facilities. Re-evaluate the risk of electromagnetic field exposure prior to equipment structure or antenna modification. Re-evaluate the risk of electromagnetic field exposure prior to modification of radio frequency (RF) output specifications or parameters. Re-evaluate the risk of electromagnetic field exposure prior to modification of the site environment where equipment or facilities are located. In order to avoid the possibility of exceeding the Europe radio frequency exposure limits, human proximity to the equipment shall not be less than 10.76 m This equipment complies with FCC/IC radiation exposure limits set forth for an uncontrolled environment.This equipment should be installed and operated with minimum distance 7.09m between the radiator and your body. Restricted Areas An area with excessive electromagnetic field exposure is considered hazardous and must be at a specified distance away from the equipment or facility as stipulated by related exposure control limits. This distance controls exposure to the electromagnetic field by personnel or the public. Maintain this distance with measures including but not limited to:
Plan to situate the equipment or facility in an area inaccessible and undisclosed to the public. Allow only authorized and trained personnel to access the site. Before entering the restricted area, personnel should be aware that it is restricted and shut down the transmitter. Set clear signs at the site to remind personnel that the area is restricted. Conduct regular post-installation monitoring and checks. Set effective physical shields and warning signs in all areas with excessive electromagnetic field exposure. Install an isolating device around the equipment structure. Comply with local regulations during operation. Safety Information Installation and Usage of a Wireless Base Station Transceiver A base transceiver station (BTS) is designed to emit less RF electromagnetic radiation than the maximum standard hazardous limit. A normal working BTS is therefore not harmful to the public and operating personnel. Defective antenna cables or other defects may however result in the emission of excessive RF electromagnetic radiation. Personnel must abide by the following rules during BTS installation and operation:
Read through all safety recommendations and comply with local regulations before proceeding. Before installing or maintaining an antenna close to the tower or mast with a BTS and its antenna, contact related personnel to switch off the antenna transmitter. Personnel at the site should carry a radiation monitoring and alarm instrument. To shield the public from electromagnetic field exposure, abide by the following guiding principles during BTS antenna site installation:
Install rooftop antennas out of reach of human activity. Install rooftop transmission antennas away from areas with high traffic, such as the rooftop access point, telephony service point, and HVAC equipment. Install rooftop directional antennas on the periphery and facing away from buildings. Choose the most suitable antenna size by balancing better signal coverage with less visual impact. Install antennas as far away as possible without compromising local area requirements. Exercise caution when constructing a common installation site for antennas from different manufacturers, especially high-power broadcasting (FM/TV) antennas. Installing antennas in one site increases safety risks. Take special preventive measures at antenna sites next to hospitals or schools. Usage of Other Wireless Equipment Apply the safe distance from electromagnetic field exposure specified by any related equipment manual. Such distance is not specified for equipment with low RF transmit power that meets electromagnetic field exposure requirements. Such distance is not specified for specially-designed equipment that meets electromagnetic field exposure requirements for working in close proximity. Usage of High-voltage Equipment or Facilities Since only high voltages (such as over 100 kV) generate harmful electromagnetic fields, the usage of such equipment or facilities must be evaluated according to requirements. 1.5.2 Laser Radiation When handling optical fibers, do not stand close to or look into the optical fiber outlet directly without eye protection. Safety Information Use of controls or adjustment or performance of procedures other than those specified herein may result in hazardous radiation exposure. A laser transceiver is used in optical transmission system and related test tools. The laser transmitted through unterminated optical fibers or connectors has very high power density and is invisible to human eyes. A beam of light can cause damage to the retina. Looking into the end of an exposed optical fiber or broken optical fiber without eye protection from a distance of more than 150 mm (5.91 in.) will not cause eye injury. However, eyes may be damaged if an optical tool such as a microscope, magnifying glass, or eye loupe is used to view a bare optical fiber end. Observe the following precautions to avoid laser radiation hazards:
Only trained personnel are authorized to operate the laser. Wear protective goggles during laser or optical fiber operation. Disconnect the light source before disconnecting optical fiber connectors. Use optical fiber caps to protect the disconnected optical fiber connectors. Use an optical power meter to measure optical power and verify that the light source is disconnected. Do not look into an exposed optical fiber or connector terminal until the light source is off. Immediately install dust-proof caps onto exposed optical fiber connectors. Ensure that the optical fibers and light source are disconnected before fiber cutting or splicing. Ensure that there is no laser radiation before opening the front door of the optical transmission system. Do not view optical fiber terminals or connectors with a microscope, magnifying glass, or eye loupe. 1.6 Mechanical Safety Hoisting Heavy Objects Avoid walking areas under heavy objects being hoisted. Hoisting operators must be trained and qualified. Hoisting tools must be checked and complete. Before hoisting, fasten all tools to fixed load-bearing objects or walls. During hoisting, ensure that angles between lifting straps are under 90, as shown in Figure 1-2. Figure 1-2 Hoisting heavy objects Safety Information Ladder Usage Before using a ladder, Check that it is intact and confirm its load bearing capacity. Do not overload it. A gradient of 75 is recommended between the ladder and the ground as measured with an angle square shown in Figure 1-3. Place the wider feet at the bottom or take protective measures to avoid skidding. Place the ladder on a stable surface. Figure 1-3 Ladder tilt angle When climbing a ladder:
Maintain your center of gravity within the ladder edges. Safety Information Keep your body balanced when climbing. Do not climb higher than the fourth rung from the top. To climb to a rooftop, ensure that the ladder has at least 1 m (3.28 ft.) extra height above the rooftop, as shown in Figure 1-4. Figure 1-4 1 m (3.28 ft.) excess height of the ladder above the rooftop Drilling Holes Pay attention to the following safety precautions when drilling holes on the wall or ground. Do not drill unauthorized holes on cabinets. Incorrectly drilled holes will damage cabinet electromagnetic shielding and internal cables. Metal scraps generated in drilling may also short circuit the cabinet boards. Wear protective goggles and gloves when drilling. Cover equipment before drilling to prevent metal scraps from entering the equipment interior. Remove these scraps immediately after drilling. Transporting Heavy Objects Adopt a load bearing posture before moving heavy objects to avoid sprains or other injuries. When transporting a cabinet, keep your back straight and avoid sudden movement. When transporting equipment by hand, wear gloves to protect against sharp edges. When moving or lifting a shelf, hold it by its handles or bottom edge instead of the handles of installed cabinet modules such as power modules, fan modules and boards. 1.7 Maintenance Safety Safety Information Wear an ESD wrist strap when replacing accessories or parts. Ensure that one end is grounded and the other end properly contacts the skin. When replacing parts, account for all parts, bolts, and tools and prevent them from dropping into fans and causing damage to equipment. When replacing cabinet shelves or parts, exercise caution when pulling them out to prevent injury resulting from falling objects. Fuse Replacement Replace fuses with the same type and rating. Disconnect the equipment power supply before replacement to prevent electric shock and injury. Install replaceable fuses on the panel next to the AC/DC power input or output ports. Refer to the specifications of backup or panel fuses to select the fuse type for replacement. Using fuses of different specifications may cause equipment damage, bodily injury, and financial loss. Fuse Welding If the fuse rating is silkscreened on the board, Huawei authorized personnel will replace fuses with the specified rating. If the fuse rating is not silkscreened on the board, do not maintain board fuses on site. Return them to the depot for repair. Huawei authorized personnel replace fuses using the supplier model and rating in the bill of materials (BOM). Power Distribution Box and Board Replacement Wear insulation gloves and ensure that the external-equipment circuit breaker is disconnected before proceeding. When replacing a board, do not touch its components to avoid damage. Install filler panels in all vacant slots. Fan Replacement Pull out a part of the fan module by its handles, wait until the fan completely stops rotating, and then remove the fan module from the subrack. Keep fingers away from fan blades.
