Symbols This symbol indicates that casualty or serious accident may occur if you ignore the safety instruction. This symbol indicates that serious or major injury may occur if you ignore the safety instruction. This symbol indicates that the operation may be easier if you pay attention to the safety instruction. In a thunderstorm, do not perform operations on high voltage and AC power supply facilities or on a steel 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. 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. 1 Copyright Huawei Technologies Co., Ltd. 2009. All rights reserved.

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. It is recommended that the bottom of the main fixture be 1200 mm to 1600 mm above the ground for easy maintenance. Arrow 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. Installation position for the auxiliary fixture. You may fit one end of the auxiliary fixture on one dual-nut bolt assembly before installation. And then fit the other end on the other dual-nut bolt assembly during the installation. 6 Installing the RRU on a Metal Pole Use an adjustable wrench (21 mm) to tighten the nut. In this way, the main and auxiliary fixtures are securely mounted on the pole. When tightening the nuts, ensure that the two dual-nut bolt assemblies are tightened simultaneously. The fastening torque is 35 N m to 40 N m. Install the RRU on the main fixture. The screw is a non-fixed one and is for removing the RRU. 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. 7 Installing the RRU on a Metal Pole b Installing Two RRUs in Back-To-Back Mode Install an RRU first. For details, see page 6 Installing a Single RRU in Ordinary Mode. Install the main fixture of another RRU. Ensure that the main and auxiliary fixtures are perfectly fitted. Reinstall the cover plate and attachment plate on the second RRU to interchange their positions. M6x16 M6x16 Install the second RRU on the main fixture. Ensure that the cabling cavities of the two RRUs face the same direction when installing the RRUs.

The following figures show the installation positions for a fourth RRU. 10 Installing the RRU on a Wall Place the auxiliary fixture on the wall at the installation position and then mark the anchor points by using a marking pen. Drill holes at the anchor points and then install the expansion bolt assemblies. M10x65 bolt Spring washer 10 Plastic tube Flat washer 10 Expansion tube After the expansion bolt is removed, dispose of the plastic tube. It is recommended that the bottom of the auxiliary fixture be 1200 mm to 1600 mm above the ground. Do not hammer the bolt entirely into the expansion tube, and leave 20 mm to 30 mm of the bolt outside the wall. When RRUs are installed on a wall, the specifications of the wall are as follows:
1. When a single RRU is installed on the wall at the back, the wall must have the load capacity of 1.25 kN bolt stress 2. When a single RRU is installed on the wall at the side, the wall must have the load capacity of 2.0 kN bolt stress. 3. When three RRUs are installed on the wall at the side, the wall must have the load capacity of 6.0 kN bolt stress. Fit the auxiliary fixture on the expansion bolts downward, and then tighten the bolts by using a combination wrench (17 mm). Install the main fixture. Install the RRU. 11 Installing the RRU on a U-Steel U-steel Four installation modes The procedure for installing the RRU on a U-steel is the same as that for installing the RRU on a metal pole.

Sufficient space is reserved for equipment maintenance. The RRU is properly installed. The cover plate is fastened to the RRU cabling cavity. Waterproof check: The empty cable troughs in the cabling cavity of the RRU are waterproofed. The cover plate is tightly buckled on the cabling cavity of the RRU. The RF ports that are not connected with RF cables are capped and waterproofed. No joint lies in the middle of the power cable or the PGND cable. The lugs at both ends of the power cable or the PGND cable are securely soldered or crimped. The power cable and PGND cable are not short-circuited or reversely connected and are not damaged or broken. The working grounding and protection grounding of the base station and the lightning protection grounding of the building share one group of grounding conductors. The connectors of signal cables are intact. All labels, tags, and nameplates are correct, legible, and complete. All the labels at both ends of the cables, jumpers and feeders are legible. Set the power switch to OFF and check the input voltage (-48 V DC power supply:
-36 V DC to -57 V DC. AC power supply: 150 V AC to 300 V AC). Set the power switch to ON and check the RUN LED (the RUN LED is ON for 1s and OFF for 1s). 22 Powering On the RRU The RRU should be powered on in 24 hours after being unpacked.
