represent all the safety instructions. They are only supplements 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 supplements 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 qualified professionals are allowed to remove safety facilities and check 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 fire, immediately leave the building or the equipment room, and turn on
the fire alarm bell or make an emergency call. Do not enter a building 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
This section describes environmental safety precautions.
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

Be careful to prevent injury when moving heavy objects.
A power distribution cabinet is heavy. It is recommended that you move it with the help of
a tool such as the pallet truck.
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.

3.2 Introduction
The integrated PDC is an intelligent AC PDC especially designed for small- and
medium-sized modular data centers. It combines air conditioner PDC, and IT PDC, features
space saving, cost saving, and high integration, and applies to the power supply and
distribution system of small- and medium-sized modular data centers.
When the load power is small, the air conditioner and IT power distribution functions can be
integrated in a cabinet to save installation space and reduce costs.
The integrated PDC, as the EOS, provides power supply to air conditioners and IT loads in
the modular data center.

Both IT power distribution input of the integrated PDC and power distribution input of the air
conditioner have single-input and dual-input scenarios. The appearance of the cabinets is also
similar.
The following figure uses the dual-input scenario as an example for IT power distribution and
air conditioner power distribution.
