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 hurt human eyes.

The high voltage power supply provides power for the device operation. Direct or indirect
contact (through damp objects) with high voltage and AC mains supply may result in
serious injury.
Non-standard and 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, follow local safety regulations
and rules.
During the installation of the AC power supply facility, follow the local safety
regulations.
Before cable connections, ensure that the mains switch, bypass switch, and mains
distribution switch are OFF.
Dedicated tools must be used during high voltage and AC operations. Avoid using
ordinary tools.
When 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.
Ground the device before powering it on. Otherwise, personal injury or device damage
may be caused by high leakage current.
If a "high electrical leakage" tag is attached to the power terminal of the device, you must
ground the protective ground terminal to the device enclosure before powering the device
on, thereby preventing electric shocks.
The UPS is a large leakage current device. Do not configure a circuit breaker that has the
leakage current protection function.
Before moving or reconnecting the UPS, disconnect the mains and batteries and wait
about five minutes after the UPS completely powers off. Otherwise, electric shocks may
occur.
