4.3 Connecting the Power Supply
CAUTION
：
Please operate strictly according to the following steps!
This is to ensure personal safety and longevity of
equipment.
WARNING:
The switch on UPS is used to control the battery supply,
but not the utility supply and the UPS output. The utility input
is controlled by an additional external air circuit breaker. If
you want to do maintenance inside the equipment, you must
first turn off the external air circuit breaker to disconnect the
utility input power supply. Also, turn off the inverter and the
battery connection inside the unit.
