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.Symbols

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 power-off state of the equipment is 24 hours during maintenance.

The following figure describes the specifications for the metal pole, angle steel, and U-steel where the RRU is installed.

Metal pole Angle steel U-steel

Angle steel or U-steel

As shown in the figure, the angle between the vertical direction and the angle steel or U-steel where the RRU is installed must be less than 10 degrees.

• A 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.• It is recommended that only one RRU be installed on a U-steel or angle steel.• 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 wall, the requirements are as follows:• For one RRU, the wall has a weight-bearing capacity of 68 kg.• 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.

The brackets cannot be combined when the RRUs are installed on the wall.

• For details on how to add OT terminals to the power cable of the RRU, see pages 32 to 34 "Adding OT Terminals to the Power Cable of the RRU".• When wrapping the waterproofing tape, apply even force to extend the tape until the width of the tape is 1/2 of the original width.• Wrap the joint spirally upward, downward, and then upward again. In other words, the joint is wrapped by three layers of the tape. Ensure that the two immediate layers overlap with each other about half the width of the tape. For details, see page 35 “Waterproofing Outdoor Cables”.

• Use the power cable clip to press the shielding layer tightly and ensure that the lower part of the shielding layer does not exceed the position shown in the preceding figure.• Ground the shielding layer at the other end of the power cable.• After the cables are installed on the RRU, insert the waterproofing fillers into the idle cable troughs.• Do not remove the dustproof cap from the idle antenna port, and use the waterproofing tape to wrap the joint.

• The screws on the cover plate should be tightened until the fastening torque is 1.4 N·m.• Tighten the screws on the cover plate of the cabling cavity in the sequence shown in the figure.
