Power Grid Requirements
A standard UPS can connect to a three-phase, five-wire (L1, L2, L3, N, PE) TT, TN-C, TN-S,
and TN-C-S AC power distribution system (IEC60364-1).
Local Laws and Regulations
Equipment operations must comply with local laws and regulations. The safety instructions in
this document are only supplemental to local safety regulations.
Personal Requirements
Only Huawei engineers or engineers certified by Huawei are allowed to perform UPS
commissioning and maintenance. Otherwise, human injury or equipment damage may occur,
and any resulting UPS faults will be beyond warranty scope.
Personnel who plan to install or maintain Huawei equipment must receive thorough training,
understand all necessary safety precautions, and master the correct operation methods.
Trained and qualified personnel, or personnel certified or authorized by Huawei are:
Allowed to install, operate, and maintain the equipment.
Allowed to remove safety facilities and inspect the equipment.
Allowed to replace or change the devices or components (including software).
Operation personnel must report faults or errors that might cause serious safety issues to
related owners.
This product should be installed and used according to the installation and technical,
specification requirements found in this manual. Otherwise, the product may be damaged,
and the resulting product exceptions or component damage will be beyond the warranty
scope.
Grounding Requirements
Devices to be grounded (excluding the energy storage unit) must meet the following
requirements:
When installing a device, install the ground cable first. When removing a device, remove
the ground cable at the very end.
Do not damage the ground conductor.
Do not operate devices if the ground conductor is not installed. Before operating a device,
check the electrical connection of the device to ensure that it is securely grounded.
Personal Safety
Do not operate the product, or handle cables, during thunderstorms.
To avoid electric shocks, do not connect safety extra-low voltage (SELV) circuits to
telecommunication network voltage (TNV) circuits.
Before operating a device, wear electrostatic discharge (ESD) clothes, ESD gloves, and
an ESD wrist strap. Remove any conductors (such as jewelry or watches) before the
operation to avoid electric shocks or burns.

In the case of fire, leave the building or the equipment room immediately, and turn on the
fire alarm bell or make an emergency call. Never enter the building on fire in any case.
If the cabinet provides an ESD jack, wear an ESD wrist strap and insert the ground
terminal of the ESD wrist strap into the jack.
Ensure all switches are turned to OFF during device installation.
Power on the UPS only after authorized engineers arrive at the site.
If a C2 UPS is used in residential areas, additional measures must be taken to prevent
radio frequency interferences.
If the UPS is used for life-supporting medical apparatus and facilities such as lifts where
adequate care has to be taken to ensure personal safety, discuss with the manufacturer in
advance about the applicability, settings, management, and maintenance of the UPS,
which require special considerations during design.
Device Safety
Before operation, ensure that the device is firmly anchored to the floor or other solid
objects, such as a wall or an installation rack.
Ensure ventilation vents are unblocked while the system is operating.
Before powering on the device, ensure that all the screws inside it are securely tightened
and will not fall off during operation.
After the installation, remove packing materials from the equipment area.
Replace danger signs that have worn out or are unreadable.
A UPS can be used to serve resistive-capacitive loads, resistive loads, and
micro-inductive loads. It is recommended that a UPS not be used for pure capacitive
loads, pure inductive loads, and half-wave rectification loads. It does not apply to energy
feedback loads.
Do not alter the UPS internal structure or installation procedure unless consent from the
manufacturer is given.
Never use water to clean electrical components inside or outside the UPS.
Do not drill holes into a cabinet.
1.2 Electrical Safety
High Voltage
The high voltage power supply provides power for the device operation. Direct or indirect
contact with high voltage power sources may result in fatal injury.
Non-standard or incorrect high voltage operations may result in fire and electric shocks.
The personnel who install the AC facility must be qualified to perform high voltage and
AC operations.
When selecting, connecting, and routing power cables, ensure compliance with local
laws and regulations.

When operating theAC power supply facility, ensure compliance with local laws and
regulations.
Before connecting cables to the UPS, ensure that the input power and mains power
distribution switches and output power distribution switch are turned off.
Use only dedicated tools during high voltage andAC operations.
If the operation is performed in a damp environment, ensure that the device is dry. When
water is found in the rack or the rack is damp, switch off the power supply immediately.
High Leakage Current
Ground a device before powering it on. Otherwise, personal injury or device damage may
occur.
If a "high leakage current" tag is attached to the panel of the device, ground the protective
ground terminal on the device enclosure before connecting theAC power supply to
prevent electric shocks.
The UPS can generate high leakage currents. Using a circuit breaker that has the leakage
current protection function is not recommended.
The leakage current of the 3 kVAUPS is less than or equal to 70 mA.
When selecting the earth leakage circuit breaker (ELCB), consider the leakage current of
the UPS and downstream loads.
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 damage eyesight.
Before moving or reconnecting the UPS, disconnect the mains and batteries, open the
output power distribution switch, and wait a period of at least 5 minutes after the UPS
completely powers off. Otherwise, electric shocks may occur.
Before installing or removing the power cable, open the power switch.
Before connecting a power cable, check that its label is correct.
Fuse
If a fuse needs replacing, ensure the new fuse is of the same type and specifications so that the
system runs safely.
