4. Operation
Explanation
Usual operation
●
You may either leave the power switch of the unit on (operation status) or turn it off when shutting down the
connected system. You can choose either of the operation methods for your convenience.
●
Connecting the UPS to a wall outlet (commercial power) charges the battery.
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 still 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 resumes power supply. If you do not want to restart connected
devices, turn off the power switch of either the unit or the connected devices.
4-2 Start and stop procedures and basic operation

When the 100 VAC input plug is connected to a wall outlet and the power switch is
in the OFF position:

Start procedure
Operation
Turn on the power switch of the UPS.
• The beeper sounds and the Power Output Lamp goes on.
• After 5 seconds, the self-diagnostic test is performed in Battery Mode for approximately 3 seconds.
(If the battery voltage is low, the self-diagnostic test is not performed. It is automatically executed after
the battery is charged.)
• When the self-diagnostic test finishes successfully, switching to 100 VAC output from commercial power
is performed and normal operation starts.
• If the self-diagnostic test is not executed, the UPS immediately starts outputting 100 VAC from commer-
cial power.
• During operation, the battery is charged automatically.
