1 Safety Precautions
1.1 General Safety Precautions
General Safety Principles
To ensure safety of humans and the equipment, pay attention to the safety
symbols on the equipment and all the safety instructions in this document.
The "Note", "CAUTION", "WARNING", and "DANGER" statements in this
document do not represent all the safety instructions. They are only supplemental
to the safety instructions.
Local Safety Regulations
When operating Huawei equipment, you must follow the local laws and
regulations. The safety instructions in this document are only supplemental to the
local laws and regulations.
Personnel Requirements
Personnel who plan to install, operate, and maintain Huawei equipment must be
thoroughly trained, understand all necessary safety precautions, and master
correct operation methods.
● Only trained and qualied personnel are allowed to install, operate, and
maintain the equipment.
● Only personnel certied or authorized by Huawei are allowed to replace or
change the equipment or components (including software).
● Any fault or error that might cause safety problems must be reported
immediately to a supervisor.
Grounding Requirements
Equipment to be grounded must meet the following requirements:
New Main Way 2.0
User Manual 1 Safety Precautions
Issue 05 (2020-10-15) Copyright © Huawei Technologies Co., Ltd. 1

● When installing the device, always make the ground connection rst.
● When removing the device, disconnect the ground cable at the end.
● Do not damage the ground conductor.
● Do not operate the device in the absence of a properly installed ground
conductor.
● The device (or system) must be connected permanently to the protection
ground before operation. Before operating the device, check its electrical
connection to ensure that it is securely grounded.
Human Safety
● Do not operate the device or cables during thunderstorms.
● In the case of a thunderstorm, disconnect the AC power supply, and do not
use xed terminals or touch the terminals or antenna connectors.
● Before operating the device, put on electrostatic discharge (ESD) clothes, ESD
gloves, and an ESD wrist strap. Do not wear conductive articles such as
jewelry or watches when you operate the device.
● In the case of a re, immediately leave the building or the equipment room,
and turn on the re alarm bell or make an emergency call. Never enter a
building or equipment zone that is on re.
Equipment Safety
● The device must be xed securely on the oor or to other immovable objects
such as walls or mounting racks before operation.
● Do not block the ventilation vents while the device is operating.
● Tighten the screws using tools when installing panels.
● After the installation, remove packing materials from the equipment area.
1.2 Electrical Safety
High Voltage
D ANGER
● The high voltage power supply provides power for the equipment operation.
Direct or indirect contact (especially with a damp object) with the high voltage
power supply may result in fatal injury.
● Non-standard and improper high-voltage operations may result in accidents
such as re or electric shock.
New Main Way 2.0
User Manual 1 Safety Precautions
Issue 05 (2020-10-15) Copyright © Huawei Technologies Co., Ltd. 2

High Electricity Leakage
CA UTION
Ground the equipment before powering it on. Otherwise, personal injury or
equipment damage may be caused by high electricity leakage.
If a "high electricity leakage" label is attached near the power terminal of the
equipment, you need to ground the protective ground terminal on the enclosure
before connecting the AC power supply; otherwise, electric shock as a result of
electricity leakage may occur.
Power Cable
D ANGER
Do not connect or disconnect power cables with power on. Transient contact
between the core of a power cable and a conductor may generate electric arcs or
sparks, which may cause re or hurt human eyes.
● Before installing or removing a power cable, turn o the power switch.
● Before connecting a power cable, check that the label on the power cable is
correct.
Fuse
CA UTION
To ensure that the equipment runs safely, if a fuse is blown, replace it with a new
fuse of the same type and specications.
1.3 Environmental Safety
D ANGER
Do not place or operate a device in a ammable, explosive, or smoky
environment.
Operating any electronic device in a ammable environment can be fatal.
1.4 Mechanical Safety
New Main Way 2.0
User Manual 1 Safety Precautions
Issue 05 (2020-10-15) Copyright © Huawei Technologies Co., Ltd. 3

Moving Sharp Objects
CA UTION
Wear protective gloves when moving sharp objects.
Moving Heavy Objects
Wear protective gloves to protect hands when moving heavy objects.
CA UTION
Be careful to prevent injury when moving heavy objects.
1.5 Routing Cables
Binding Signal Cables
NO TICE
Signal cables must be bound separately from strong-current cables and high-
voltage cables.
Laying Out Power Cables
When the temperature is very low, violent impact or vibration may damage the
power cable sheathing. To ensure safety, comply with the following requirements:
● Power cables should be laid out or installed only when the temperature is
higher than 0°C.
● Cables stored at subzero temperatures must be stored at room temperature
for at least 24 hours before they are laid out.
● Handle power cables with caution, especially at a low temperature. Do not
drop the power cables directly from the vehicle.

1.6 Information About Foreign Objects Near the
Installation Position of the NMW
The purpose of this note is to provide information and warnings about the
potential risks of the operational integrity of an installed NMW system. These risks
are caused by foreign objects in or near the NMW, relevant auxiliary equipment, or
components.
WARNING
● If conductive materials have entered the channel in the NMW, relevant
auxiliary equipment, or components, equipment faults may occur.
● Potential risks include damage to the installed NMW and subsequent power
derating and power failure of loads at critical positions.
● Huawei uses the IP30 standard in NMW design to ensure that live parts are not
in contact with the exterior and that no foreign objects will enter the
equipment during operation.
● When the NMW bae plate and cover are open and electrical wiring terminals
are exposed by the electrical contractor or installation personnel who are
setting up a power line connection, it cannot be ensured that no foreign object
will enter the NMW during onsite installation.
● It is common to have someone working in the same room as the NMW during
onsite installation. Sometimes some people may be working above the NMW,
relevant auxiliary equipment, or components.
● To avoid serious damage to the onsite operation, property hazards, and
personal injury including fatal injury, it is the responsibility of each equipment
manager or construction manager to ensure that no foreign object enters the
NMW, relevant auxiliary equipment, or components.

2 Overview
NO TICE
● Use professional insulated tools when installing or operating the equipment.
● Only engineers certied by the manufacturer or its agents are allowed to
install, commission, and maintain the NMW. Otherwise, personal injury or
device damage may occur, and the resulting faults of the NMW are beyond the
warranty scope of Huawei.
● The gures provided in this document are for reference only. The actual product
prevails.
