Additional Information
When the power is restored after a power failure, the UPS is set by default to automatically
restart and supply power.
If you do not want to restart the connected devices, "Setting" switch 2 can be used to select
whether or not auto restart is performed, or turn OFF the "Power" switch of the connected
devices (See also "3-1-4 Setting Switch").
■ Operation when stopping
Before stopping the commercial power to the unit, turn OFF the "Power"
switch of the unit.
● The unit enters Battery Mode when commercial power is stopped. If you
frequently use the unit in Battery Mode, the battery life may be significantly
shortened.
Press and release the "Power" switch of the UPS, and then the "Power" switch turns OFF.
The power output from the UPS stops at the same time.
Additional Information
Even if you turn off the "Power" switch, if AC is supplied from commercial power, the battery
is automatically charged.
