General Installation Requirements
The personnel in charge of installation and maintenance must be trained and master the correct
operating methods and safety precautions before beginning work. The rules for installing and
maintaining the device are as follows:
lOnly the trained and qualified personnel can install, operate and maintain the device.
lOnly the qualified specialists are allowed to remove the safety facilities, and repair the
device.
lAny replacement of the device or part of the device (including the software) or any change
made to the device must be performed by qualified or authorized personnel of Huawei.
lAny fault or error that might cause safety problems must be reported immediately to the
personnel in charge.
Grounding Requirements
The following requirements are applicable to the device to be grounded:
lGround the device before installation and remove the ground cable after uninstallation.
lDo not damage the ground conductor.
lDo not operate the device in the absence of a ground conductor.
lThe unit (or system) must be permanently connected to the protection ground before
operation. Check the electrical connection of the device before operation and ensure that
the device is reliably grounded.
Safety of Personnel
lWhen lightning strikes, do not operate the device and cables.
lWhen lightning strikes, unplug the AC power connector. Do not use the fixed terminal or
touch the terminal or antenna connector.
NOTE
The previous two requirements are suitable for the wireless fixed terminal.
lTo prevent electric shock, do not connect safety extra-low voltage (SELV) circuits to
telecommunication network voltage (TNV) circuits.
lTo prevent laser radiation from injuring your eyes, never look into the optical fiber outlet
with unaided eyes.
lTo prevent electric shock and burns, wear the electrostatic discharge (ESD) clothing, gloves
and wrist strap, and remove conductors such as jewelry and watch before operation.
lWhen there is a fire, evacuate the building or the equipment area and press the fire alarm
bell, or call the firehouse for help. Never enter a building in a fire again.
Device Safety
lBefore operation, the device must be secured on the floor or other fixed objects, such as
the walls and the mounting racks.
lDo not block ventilation openings while the system is running.
lWhen installing the panel, tighten the screw with the tool.

lAfter installing the equipment, clear the wrapper and packing material out of the equipment
area.
1.2 Electricity Safety
High Voltage
DANGER
lThe 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.
lNon-standard and improper high voltage operations may result in fire and electric shock.
lThe personnel who install the AC facility must be qualified to perform operations on high
voltage and AC power supply facilities.
lWhen installing the AC power supply facility, follow the local safety regulations.
lWhen operating the AC power supply facility, follow the local safety regulations.
lWhen operating the high voltage and AC power supply facilities, use the specific tools
instead of common tools.
lWhen the operation is performed in a damp environment, ensure that water is kept off the
device. If the cabinet is damp or wet, shut down the power supply immediately.
Thunderstorm
The following requirements are suitable only for the wireless base station or the device with an
antenna or GPS antenna.
DANGER
In a thunderstorm, do not perform operations on high voltage and AC power supply facilities or
on a steel tower and mast.
High Electrical Leakage
CAUTION
Ground the device before powering on the device. Otherwise, the personnel and device are in
danger.
If the "high electrical leakage" flag is stuck to the power terminal of the device, you must ground
the device before powering it on.

Power Cable
CAUTION
Do not install and remove the power cable with a live line. Transient contact between the core
of the power cable and the conductor may generate electric arc or spark, which may cause fire
or eye injury.
lBefore installing or removing the power cable, turn off the power switch.
lBefore connecting the power cable, ensure that the power cable and label comply with the
requirements of the actual installation.
Fuse
CAUTION
To ensure that the system runs safely, when a fuse blows, replace it with a fuse of the same type
and specifications.
Electrostatic Discharge
CAUTION
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 (LSI).
lThe human body generates a static electromagnetic field in the following situations:
movement of body parts, clothes friction, friction between shoes and the ground, and
holding plastic in hand. The static electromagnetic field will remain within the human body
for a long time.
lBefore contacting the device, plug boards, circuit boards, and application specific
integrated circuits (ASICs), wear a grounded ESD wrist strap. It can prevent the sensitive
components from being damaged by the static electricity in the human body.
Figure 1-1 shows how to wear an ESD wrist strap.

1.3 Inflammable Environment
DANGER
Do not place the device in the environment that has inflammable and explosive air or fog. Do
not perform any operation in this environment.
Any operation of the electrical device in the inflammable environment causes danger.
1.4 Battery
Battery
DANGER
Before handling the storage battery, read the safety precautions for the handling and connection
of the storage battery.
lIncorrect operation of storage batteries may cause danger. During operation, prevent the
batteries from short-circuit and prevent the electrolyte from overflowing and leakage.
lElectrolyte overflow may damage the device. It will corrode the metal parts and the circuit
boards, and ultimately damage the device and cause short-circuit of the circuit boards.

lThe storage battery is of high electricity capacity. Incorrect operation may cause short-
circuit and injure the personnel.
General Operations
Before installing and maintaining the storage battery, ensure the following:
lUse special insulation tools.
lUse eye protection devices and operate with care.
lWear rubber gloves and an apron in case of an electrolyte overflow.
lAlways keep the battery upright when moving. Do not place the battery upside down or tilt
it.
lAlways keep the charging power source OFF during any operation and maintenance.
Short-Circuit
DANGER
Short-circuit of the battery may cause injury. Although the voltage of a battery is low, high
transient current generated by short-circuit will release a surge of power.
Keep metal objects away from the battery to prevent short circuit. If they have to be used,
disconnect the battery in use before performing any other operation.
Harmful Gas
CAUTION
Do not use unsealed lead-acid storage batteries, because the gas emitted from it may result in
fire or device corrosion. Lay the storage battery horizontally and fix it properly.
The lead-acid storage battery in use will emit flammable gas. Therefore, store it in a place with
good ventilation and take precautions against fire.
High Temperature
CAUTION
High temperature may result in distortion, damage, and electrolyte overflow of the battery.
When the temperature of the battery exceeds 60℃, check whether there is acid overflow. If acid
overflow occurs, handle the acid immediately.
