All rights reserved.Following All Safety PrecautionsBefore any operation, read the instructions and precautions in this document carefully to minimize the possibility of accidents.The Danger, Caution, and Note items in the documents do not cover all the safety precautions that must be followed. They only provide the generic safety precautions for operations.When operating Huawei products and equipment, you must comply with safety precautions and special safety instructions related to corresponding equipment provided by Huawei. The safety precautions in the document are related to only Huawei products. Huawei is not liable for any consequence that results from the violation of universal regulations for safety operations and safety codes on design, production, and equipment use. Complying with the Local Safety RegulationsWhen operating the device, comply with the local safety regulations. The safety precautions provided in the documents are supplementary. You must comply with the local safety regulations.Qualified Personnel OnlyThe personnel in charge of installation and maintenance must be trained and master the correct operating methods and safety precautions before beginning work.SymbolsSafety 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 power-off state of the equipment is 24 hours during maintenance.Safety InformationIndicates a hazard with a high level of risk, which if not avoided,will result in death or serious injury.DANGERWARNINGCAUTIONTIPNOTEIndicates a hazard with a medium or low level of risk, which if not avoided, could result in minor or moderate injury.Indicates a potentially hazardous situation, which if not avoided,could result in equipment damage, data loss, performance degradation, or unexpected results.Indicates a tip that may help you solve a problem or save time.Provides additional information to emphasize or supplement important points of the main text.

5Installation ModesMetal pole Angle steel U-steelThe following figures show the installations of multiple RRUs on the metal poles.The RRU can be installed on the tower. For details, see page 26 Lifting the RRU and Installation Components to the Tower.60mm～114mm63mm～80mm63mm ～80mm30mm～50mm50mm～100mm63mm～80mm30mm～50mmThe following figure shows the specifications of the metal pole, angle steel, and U-steel where the RRU is installed.zA maximum of two RRUs can be installed on a metal pole with a diameter of 60 mm to 76 mm, and the installation mode must be standard mode. Three or more RRUs must be installed on a metal pole with a diameter of 76 mm to 114 mm in a centralized way. zIt is recommended that only one RRU be installed on a U-steel or angle steel.zWhen 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 U-steel or angle steel and the longitudinal direction cannot exceed 10 degrees.installation carrier

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.
7Installing the RRU on a Metal PoleInstalling a Single RRU in Ordinary Modea2. Install the auxiliary fixture between the nuts of the dual-nut bolt assembly on the main fixture.Dual-nut bolt assembly Ensure that the arrow on the auxiliary fixture is upward.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•mWhen tightening the nuts, ensure that the two dual-nut bolt assemblies are tightened simultaneously. The fastening torque is 40 N• m.
8Installing the RRU on a Metal Pole4. Install the RRU on the main fixture.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.The screw is a non-fixed one and is for removing the RRU.Installing Two RRUs in Back-To-Back Modeb2. Install the main fixture of another RRU. Ensure that the main and auxiliary fixtures are perfectly fitted.1. Install an RRU first. For details, see page 7 Installing a Single RRU in Ordinary Mode.
