You must comply with the local safety regulations. Qualified Personnel Only The personnel in charge of installation and maintenance must be trained and master the correct operating methods and safety precautions before beginning work. Symbols DANGER Indicates a hazard with a high level of risk, which if not avoided,will result in death or serious injury. WARNING Indicates a hazard with a medium or low level of risk, which if not avoided, could result in minor or moderate injury. CAUTION Indicates a potentially hazardous situation, which if not avoided,could result in equipment damage, data loss, performance degradation, or unexpected results. TIP Indicates a tip that may help you solve a problem or save time. NOTE Provides additional information to emphasize or supplement important points of the main text. Safety of Personnel • The high voltage power supply provides power for running the system. Direct contact with the high voltage power supply or contact through damp objects may result in fatal danger. • Non-standard and improper high voltage operations may result in fire and electric shock. • In a thunderstorm, do not perform operations on high voltage and AC power supply facilities or on a steel tower and mast. • Ground the device before powering on the device. Otherwise, the personnel and device are in danger. • Power off the device before performing operations on the power supply equipment. • High power radio-frequency signals are harmful to human body. Before installing or maintaining an antenna on a steel tower or mast with a large number of transmitter antennas, the operator should coordinate with all parties to ensure that the transmitter antennas are shut down. • When handling optical fibers, do not stand close to, or look into the optical fiber outlet with unaided eyes. • Protect yourself when drilling holes. Flying dust may hurt your eyes or you may inhale the dust. • Power off the batteries before connecting the cables to the batteries. Otherwise, casualties may occur. • When working at a height, be cautious about falling objects. Device Safety • Check the electrical connection of the device before operation and ensure that the device is reliably grounded. • The static electricity generated by the human body may damage the electrostatic sensitive components on the circuit board, such as the large-scale integrated circuit (LIC). Wear an ESD wrist strap or ESD gloves when performing the operation. • When working on batteries, take measures to prevent short circuits in the batteries and electrolyte spill/loss. The electrolyte may erode metal and boards, or even cause rust of the equipment or short circuits in the boards. • When the equipment is unpacked, it must be powered on in 24 hours. The maximum duration of the poweroff state of the equipment is 24 hours during maintenance. Copyright © Huawei Technologies Co., Ltd. 2009. All rights reserved.

Three or more RRUs must be installed on a metal pole with a diameter of 76 mm to 114 mm in a centralized way. z It is recommended that only one RRU be installed on a U-steel or angle steel. z When installed on a tower, one RRU can be installed only in standard mode or reverse mode rather than side-mounted. Two RRUs cannot be installed in back-to-back mode. When the RRU is installed on a U-steel or angle steel, the angle between the Usteel or angle steel and the longitudinal direction cannot exceed 10 degrees. installation carrier The RRU can be installed on the tower. For details, see page 26 Lifting the RRU and Installation Components to the Tower. The following figures show the installations of multiple RRUs on the metal poles. Installation Procedure Start Install the RRU on a metal pole (page 7~11) Install the RRU on a wall (page 12~14) Install the RRU on a U-steel (page15) Install the RRU on a angle steel (page15) Install the RRU cables (page16~22) Check the installation (page 23) Power on the RRU (page 23) End Components Delivered with the RRU Attachment plate Auxiliary fixture Main fixture M10x110 Bolt Fixture assembly for installing the RRU Back of the RRU Installing the RRU on a Metal Pole a Installing a Single RRU in Ordinary Mode 1. Before installing the main fixture, ensure that the contact piece on the fixture is fixed. 2. When installing the main fixture, keep the arrow on the main fixture upward. Arrow It is recommended that the bottom of the main fixture be 1200 mm to 1600 mm above the ground for easy maintenance. Installing the RRU on a Metal Pole a Installing a Single RRU in Ordinary Mode 2. Install the auxiliary fixture between the nuts of the dual-nut bolt assembly on the main fixture. Ensure that the arrow on the auxiliary fixture is upward. Dual-nut bolt assembly You can fit the auxiliary fixture on one of the dual-nut bolt assemblies before the installation. Thus, you can simply install the auxiliary fixture by fitting the other end of it on the other dual-nut bolt assembly. Fit the auxiliary fixture into the dual-nut bolt assemblies. 3. Use an adjustable wrench (with the diameter of at least 21 mm) to tighten the dual-nut bolt assemblies. In this way, the main and auxiliary fixtures are securely mounted on the pole. 40N•m When tightening the nuts, ensure that the two dual-nut bolt assemblies are tightened simultaneously. The fastening torque is 40 N• m. Installing the RRU on a Metal Pole 4. Install the RRU on the main fixture. The screw is a nonfixed one and is for removing the RRU. 1. When you perform this operation, you need to place the foam pads or paper under the RRU to avoid any damage to the shell. 2. The RF port at the bottom of the RRU does not have load bearing capacity. Do not place the RRU on the ground on its bottom during the installation. Installing Two RRUs in Back-To-Back Mode 1. Install an RRU first. For details, see page 7 Installing a Single RRU in Ordinary Mode. 2. Install the main fixture of another RRU. Ensure that the main and auxiliary fixtures are perfectly fitted. Installing the RRU on a Metal Pole Installing Two RRUs in Back-To-Back Mode 3. Install the second RRU on the main fixture in reverse mode. Ordinary mode Ordinary mode Installing the RRU on a Wall 1. Place the auxiliary fixture on the wall at the installation position , use a level bar to measure the levelness of the fixture, and then mark the anchor points by using a marking pen. Level bar RRU It is recommended that the bottom of the auxiliary fixture be 1200 mm to 1600 mm above the ground. Installing the RRU on a Wall 2. Drill holes at the anchor points and then install the expansion bolt assemblies. Bolt M10x65 Ø14 Plastic tube Flat washer 10 Expansion tube 90° 52~60mm Spring washer 10 After the expansion bolt is removed, dispose of the plastic tube. Do not hammer the bolt entirely into the expansion tube, and leave 20 mm to 30 mm of the bolt outside the wall. 20~30mm When RRUs are installed on a wall, the specifications of the wall are as follows: z For one RRU, the wall has a weight-bearing capacity of 76 kg. z The fastening torque of the expansion bolt reaches 30 N·m, the expansion bolt works properly, and no damages such as cracks are on the wall. 3. Fit the auxiliary fixture on the expansion bolts downward, and then tighten the bolts by using a combination wrench (with the diameter of at least 17 mm). M10X65 Ensure that the arrow on the auxiliary fixture is upward. 30N•m 10 Installing the RRU on a Wall 4. Install the main fixture. 5. Install the RRU. 6. Install Multiple RRUs. 11 Installing the RRU on a U-Steel U-Steel Top view The procedure for installing the RRU on a U-steel is the same as that for installing the RRU on a metal pole.
