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.
