Output
overload
during the
bypass
operation
During the bypass operation, the
capacity of the connection device
exceeds the rated value. Reduce the
capacity of the connection device
to less than the rated value of the
UPS. In this state, even if pressing
the bypass switch (pressing the
RESET switch and the BATT
CHECK switch for approximately
3 seconds simultaneously), the
UPS will not return to the normal
operation (No.1).

A Stop due to
an output
overload
Since the UPS continued to be used
even after the capacity of the
connection device had exceeded
the rated value of the UPS, the UPS
stopped. Reduce the capacity of the
connection device to less than the
rated value of the UPS, and restart
the UPS.

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.

battery
operation
The battery voltage has dropped
since the battery operation
continued. In the rated load, the
battery operation will be completed
approximately 2 minutes later.
Evacuate important connection
