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.

Installing a Single RRU in Ordinary Mode
Install the main fixture.
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.
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.

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. T he 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.
