Safety Information
I Followrng All Safety Precautions
Before 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.
I Complying with the Local Safety Regulations
When 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.
l Qualified Personnel Only
The personnel in charge ofinstallation and maintenance must be trained and masterthe correct operating
methods and safety precautions before beginning work.
. Symbols
A This symbol indicates that casualty or serious accident may occur if you ignore
DANGER the safety instruction.
A This symbol indicates that serious or major injury may occur if you ignore the
CAUTlON safety instruction,
This symbol indicates that the operation may be easier if you pay attention to the
NOTE safety instruction,
l Safety of Personnel
The high voltage power supply proVides powerfor 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 Othervvise, the personnel and device are in danger
Power offthe 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 oftransmitter 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 yourselfwhen drilling holes. Flying dust may hurt your eyes or you may inhale the dust.
Power offthe batteries before connecting the cables to the batteries. Otherwise, casualties may occur
When working at a height, be cautious about falling objects
l Device Safety
Check the electrical connection ofthe 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 ofthe equipment or short circuits in the boards.

3. Use an adjustable wrench to tighten the nut until the fastening torque is 35 N-m to 40 N-m.
In this way. the main and auxiliary fixtures are secured on the pole,
4 Install the RRU on the main bracket. When you hear a click, you can infer that the RRU
is in position.
The screw is a non-fixed one and
can be neglected during the
installation,
It is only used when the RRU is
removed.
The RF port at the honom ofthe RRU does not have load bearing capacity. Do not place the
RR“ on the ground on its bottom during the installation.

H Binding the RRU and Installation Components
1. Bind the RRU by leading the lifting rope along the lower part of the adapting piece
and through the handle. bind the main and auxiliary brackets wit the lifting rope, and
then bind the steering rope with the handle of the RRU, as shown in the following figures
Lifting Rope
A WEI
Do not bind the Iifling rope
only on the handle when
lilting the RRU.
Steering rope
A CAUTION
1. When Ilftlng the RRU and Installatlon components to the tower, prevent the RRU from
collldlng wlth the tower.
2. The cross-sectional area ofthe lifting rope and fleeting rope is around ll] mm, not more than
25 mm. In addition. the ropes can heartheweight four times more than that ofthe RRU.

preceding figure and then tie a knot in the steering
rope at the handle ofthe RRU.
3. Installer B pulls the lilting rope. and at the same
time. installer C pulls the steering rope away from

components from colliding with the tower.
4. Installers A hold the RRU and installation
components and untie the ropes.

m NOTE
1. Cut offa 200 mm long corrugated pipe with the
diameter of25 mm.
2. Lead the fibertails labeled 1A and 15 ofthe
optical cable into the corrugated pipe by 180 mm.
3. Wrap up the corrugated pipe and optical cable
with the color tape.
4. Forthe tower made of steel pipes, tie the black
jacket to the corrugated pipe at the position 15EI
mm away from the colortape, and then Iifi the
optical cable up to the tower.
5. For the tower made of angle steel girders,
carry the optical cable onto the tower when
climbing up to the tower.
B. Afier the optical cable is Iifled up to the tower,
remove the color tape and corrugated pipe before
installing the optical cable.
