■ Actions after recovery from the power outage
● If the battery power still remains
When power outage or input power fault is solved while power is being output from the
UPS, the output automatically returns to the commercial power supply. Recharging of the
depleted battery starts.
● If the battery has run out
When power outage or input power fault is solved after the battery is depleted and power
output is stopped, the UPS automatically restarts and power output commences again.
Recharging of the depleted battery starts.
When recovery from a power outage is made, by factory default, the UPS
automatically restarts and supplies power. If you do not want to activate the
connected devices, either turn off their switches or disable the automatic start
setting for recovery from a power outage ([3. Settings] - [Boot Settings] - [Auto
Reboot]).
