Before using this document, get familiar with the actual configuration and application
scenario of the modular precision PDC.
Before using this document, make available the documents delivered with each
component.
User interfaces displayed in this document correspond to the monitor display module
(MDU) version V100R002C10SPC200B012 and are for reference only.
Put on necessary protective equipment such as the safety helmet and gloves before
entering the site.

2 Safety Precautions
2.1 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 qualified personnel are allowed to install, operate, and maintain the
equipment.
Only personnel certified 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:
When installing the device, always make the ground connection first.
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 theAC power supply, and do not use fixed
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 fire, immediately leave the building or the equipment room, and turn on
the fire alarm bell or make an emergency call. Never enter a building or equipment zone
that is on fire.
Equipment Safety
The device must be fixed securely on the floor 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.
2.2 Electrical Safety
High Voltage
The high voltage power supply provides power for the device operation. Direct or indirect
contact (especially with a damp object) with the high voltage power supply may result in
serious injury.
Non-standard and improper high voltage operations may result in fire and electric shock.
High Electrical Leakage
Ground the device before powering it on. Otherwise, personal injury or device damage may
be caused by high electrical leakage.
If a "high electrical leakage" tag is present on the power terminal of the device, you must
ground the device before powering it on.

Power Cable
Do not install or remove power cables when the device is on. Transient contact between the
core of the power cable and the conductor may generate electric arcs or sparks, which may
cause fire or injury to human eyes.
Before installing or removing a power cable, turn off the power switch.
Before connecting a power cable, verify that the label on the power cable is correct.
Fuse
To ensure that the system runs safely, if a fuse is to be replaced, the new fuse must be of the
same type and specifications.
2.3 Environmental Safety
Do not place or operate a device in a flammable, explosive, or smoky environment.
Operating any electronic device in a flammable environment can be fatal.
2.4 Mechanical Safety
Moving Sharp Objects
Wear protective gloves when moving sharp objects.
Moving Heavy Objects
Wear protective gloves to protect hands when moving heavy objects.

Be careful to prevent injury when moving heavy objects.
It is recommended that tools such as a pallet truck be used to transport the heavy PDC.
2.5 Laying Out Cables
Binding Signal Cables
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.
Store power cables for at least 24 hours at room temperature before laying out them if
they were previously stored at sub-0ºC.
Handle power cables with caution, especially at a low temperature. Do not drop the
power cables directly from the vehicle.
