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 electrostatic discharge (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.

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

z A maximum of two RRUs can be installed on a metal pole with a diameter of 60 mm to 75 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.

z It is recommended that only one RRU be installed on a U-steel or an angl e st eel. 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.

Main bracket

Main and auxiliary brackets for the RRU

Cover plate

Front Back

Attachment plate

Installing the RRU on a Metal Pole

Installing a Single RRU on a Metal Pole

1. Install the main bracket.

When installing the main bracket, ensure that the contact piece on the bracket is fixed.

1200 mm～1600 mm

Contact piece

You may fit one end of the auxiliary bracket on one dual-nut bolt assembly and then the other end on the other dual-nut bolt assembly during the installation.

2. Use an adjustable wrench to tighten the nut until the fastening torque is 40 N·m. In this way, the main and auxiliary brackets are secured on the pole.

Fasten the two dual-nut bolt assemblies

40N•m

alternatively. After the brackets are secure, use a tape to measure the spacing between the main bracket and the auxiliary bracket at the two sides and ensure that the spacing is the same.

3. Install the RRU on the main bracket. When you hear click sound, you can infer that the RRU is in position.

z The weight-bearing capacity of the RF ports at the bottom of th e RRU is low. Do not place the RRU at its bott om.

z During the operation, place the foam pad or cardboard under the RRU to prevent any damage to the housing of the RRU.

Installing the RRU on a Metal Pole

Installing Two RRUs Back-To-Back on a Metal Pole

1. Install an RRU. For details, see page 8

Installing a Single RRU on a Metal Pole.

3. Reinstall the attachment plate and cover plate on the second RRU by interchanging their positions.

2. Install the main fixture for another RRU.

4. Install the second RRU on the main bracket.

Ensure that the cabling cavities of the two RRUs face the same direction when installing the RRUs.
