Safety precautions
Notes
When moving the unit from a cold place to a warm place, leave it for several hours
before using it.
●If the unit is moved to a warmer place and the power is turned on soon, the unit failure may occur due to
condensation to the unit.
Charge the battery for at least 12 hours soon after purchasing the unit.
●If you do not use the unit for a long time after the purchase, the property of the battery may deteriorate and
the battery may become unusable.
●To charge a battery, connect the 100-VAC input plug of the unit to a wall outlet (commercial power).
When storing the unit, charge the battery for at least 12 hours and turn off the power
switch.
●Even if the unit is not used, the battery gradually discharges, and if it is left for a long time, it goes into an
over discharge state.
The backup time may become shorter or the battery may become unusable.
●The storable period of the built-in battery of the unit is 6 months after complete charging.
●If you want to store the battery longer than 6 months, connect the AC input plug of the unit to a commercial
power wall outlet for at least 12 hours within 6 months.
●Turn off the power switch of the unit during storage.
Do not short the output lines of the unit each other and the output lines to the ground.
●The unit may fail.
Do not connect the 100 VAC input plug of the unit to its Power Supply Output
Receptacle during the Battery Mode.
●The unit may fail.
Do not connect a page printer (laser printer, etc.) to the unit.
●The Commercial Power Mode and Battery Mode are repeated frequently, which may shorten the life of the
battery.
●As the peak current of a page printer is large, an excess of the connection capacity or a power failure due
to instantaneous voltage drop may be detected.
Do not use the unit for devices that malfunction due to an instantaneous power
failure of 10msec (0.01 second) or less.
●The connected device may stop due to switching time of 10msec or less.
Do not use the unit for inductive devices such as fluorescent lamps.
●Connected devices may stop due to a rectangular wave output.
●Inductive devices include devices incorporating transformers, coils, motors, and so on for their input.
Caution (for battery replacement)
●Servicing of batteries should be performed or supervised by personnel knowledgeable of
batteries and the required precautions. Keep unauthorized personnel away from batteries.

Safety precautions
Notes
Do not install or store the unit in a place exposed to direct sunlight.
●The rise of temperature may cause the built-in battery to deteriorate rapidly and become unusable.
Do not perform a withstand voltage test.
●The input circuit has a built-in surge absorption device. A withstand voltage test may break it.
●When performing an insulation resistance test, use the 250VDC range.
Before turning off the commercial power, turn off the power switch of the unit.
If you cannot turn off the power switch, it is recommended to use UPS monitoring
software to automatically stop the unit with the minimum backup time.
●When you stop commercial power, the Battery Mode starts. If you frequently use the unit in the Battery Mode
after turning off the commercial power, charging and discharging of the battery is repeated and the battery
life decreases extremely. The less the amount of charging and discharging is, the less the adverse effect on
the life becomes.
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. You can choose either of the operation methods for your convenience. We recom-
mend turning off the power switch when you do not use connected devices for a long time.
●The battery is charged when the 100 VAC input plug of the unit is connected to a wall outlet (commercial
power).
End of Battery Mode
●If a power failure lasts long, the battery discharges and power output from the unit stops. Shut down your
computer after performing appropriate procedure (for example, saving data) while the unit supplies power.
Reboot
●If the battery discharges completely during a power failure, the unit stops. After the recovery from the power
failure, the unit automatically restarts and supplies power. If you do not want to restart connected devices,
turn off the power switch of either the unit or the connected devices.
Notes
Recycling and Discarding the Battery
●The UPS uses a lead acid battery. It is recyclable, precious resources. Please recycle it
when you replace it or discard the produce you do not use any more.
