When operating the AC 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 and AC 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 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.
The leakage current of the 6 kVA UPS is less than or equal to 100 mA. The leakage current
of the 10 kVA UPS is less than or equal to 200 mA. The leakage current of the 15 kVA or
20 kVA UPS is less than or equal to 500 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.
