Safety precautions
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 recommend
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
devices, 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 43
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 54.

Notes
Check the operation beforehand if the unit is used in any mode other than “Output
200V mode”.
● In Battery Mode, the maximum voltage (peak voltage) of output (rectangular wave) may be lower than the
maximum voltage in Commercial Power Mode. For this reason, some connected devices may fail to operate
normally.
If this unit is used with an inductive device such as a coil or motor, check the operation
beforehand.
● With some types of devices, the effect of inrush current may cause this unit to stop operating properly.
In the event you transfer or sell this unit to a third party, please include all of the
documentation that came with the unit. This is to ensure that the unit is used in line
with the conditions described in the included documentation.
● This manual contains important safety-related information. Please read and understand the
contents of the manual before beginning operation.
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.
This unit uses lead acid batteries,
● Which are a valuable recyclable resource. Please recycle.
