Explanation
Usual operation
●
You may either leave the power switch of the unit ON (operation status) or turn it OFF each time when
stopping the connected system. Choose whichever operation method is more convenient. We recom-
mend turning OFF the power switch when you do not use connected devices for a long time.
●
The battery can be charged once the AC input plug of the unit is connected to a wall outlet (commercial
power).
Quitting Battery Mode
●
If a power failure lasts for an extended period of time, the battery discharges and power output from the
unit stops. Shut down your computer after performing appropriate procedures (for example, saving data)
while the unit is still supplying power.
Rebooting
●
If the battery discharges completely during a power failure, the unit stops. After recovery from the power
failure, the unit automatically restarts and supplies power. If you do not want to restart the connected de-
vices, turn OFF the power switch of either the unit or the connected devices.

Setting switch 2 can be used to select whether or not auto restart is performed. See Page 30
Scheduled operation using the UPS monitoring software
●
When performing scheduled operation in which the UPS is stopped and a device such as a breaker is
used to stop the UPS at the same time that commercial power stops, specify a period of no more than 3
months for the start of the next operation.
If you specify a period longer than 3 months, the internal timer is reset and the scheduled operation does
not start. Note that this period reduces to approximately half when the battery is dead. If a period of 3
months is exceeded, you start operation by supplying commercial power and pressing the start switch.
However, if the battery is dead, you may not be able to start operation.
In this case, replace the battery according to the instructions in “6-2 Replacing the battery” on page 42.
The cooling fan operation of BN100S/BN150S/BN220S/BN300S
●
The cooling fan starts operating at the Battery Mode due to a power failure, auto battery test, self-diag-
nostic test, etc., and automatically stops after a period of approximately 24 hours when the UPS returns
to the Commercial Power Mode and the battery is fully charged.
Pb
Take measures for handling unforeseen accidents, such as data backup and
system redundancy.
●
The output may stop when there is a circuit failure in the UPS.
