switch for approximately 3 seconds
simultaneously), the UPS will not
return to the normal operation

Battery
operation
Since the abnormalities occurred at
an input power supply, the UPS
started to supply the electric power
to the connection device from the
battery. It is not necessary to deal
with it especially.
If an input power supply returns, the
UPS will return to the normal
operation (No.1) automatically.

the battery
operation
The battery voltage dropped since
the battery operation has continued.
In the rated load, the battery
operation will be completed
approximately 2 minutes later.
Evacuate important connection
device from the UPS.
If an input power supply returns, the
UPS will return to the normal

checking
The battery check is performed. At
the manual battery check, a buzzer
sounds at the start and end of the
battery check. After the battery check
is performed for approximately 5
seconds, the UPS will return to the

no problem.

Battery check
error
There is possibility that the battery is
not fully charged. Perform the
battery check manually after
operating the UPS 12 hours or more
to charge the battery. Since an
adequate backup time cannot be
assured, evacuate important
connection device from the UPS.
If the UPS becomes this state again,
the battery is out of order. Since it is
necessary to replace the battery,
contact an agent from which you
purchased the UPS, or a maintenance
company.
