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

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.
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 the AC 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.
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.
