●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.

automatically starts regardless of the on/off state of the Power Switch and charging completes within 12
hours.
•Even if the input plug of a device you want to connect is 2-pin type, you can connect it
directly to the Power Supply Output Receptacle of the UPS. Note that if the input plug is
2-pin type with a grounding wire, connect the grounding wire to the Grounding Terminal
of the UPS.
•IF you want to use an AC adaptor, connect it to a Power Supply Output Receptacle of
the UPS with sufficient space for the connection.
●Precautions for grounding connection
The backup function of the unit will not be affected even if you do not ground it, but please note the
following:
•Attenuation effect against surge voltage caused by lightning, etc. decreases.
•If connected devices are not grounded, you may get an electric shock due to leak current when you
touch metal parts.
< 3P wall outlet > < 2P wall outlet >
Computer
Modem or other peripheral
A Grounding Terminal is provided for such cases
as the AC plug does not provide any grounding
means.

This operation check simulates a power failure by disconnecting the AC input plug from a wall outlet.)
(1) Turn on the Power Switch of this unit.
The beeper sounds and the Power Output Lamp goes on.
After 5 secounds, the self-diagnostic test is performed in Battery Mode for approximately 3 seconds.
When the self-diagnostic test finishes successfully, switching to 100 VAC output from commercial power is
performed and the following display is obtained.
(If the battery voltage is low, the self-diagnostic test is not performed and the operation starts immediately,
using output from commercial power.)
(2) Bring all the connected devices into operation.
(Including devices connected to the AC outlet of your PC.)
Operate the devices in a way in which abrupt power stop does not damage the connected devices, data,
etc.
This unit has been charged prior to shipment. However, the backup time becomes shorter when using it for
the first time due to spontaneous discharge. We recommend charging this unit before using it.
(3) Under this condition, check the display lamps and a beep of this unit.
Are they in the same status as shown below?
Are the same as shown above. ➜The operation is normal. Proceed to (4).
Are not the same as shown above. ➜The operation is abnormal. One of the description in "3. Display
and beep when a failure occurs in equipment" of "4-3 Interpreting a
beep and display" on page 21 must apply.
Take necessary measures and then proceed to (4).
(4) Disconnect the 100-VAC input plug of this unit from a wall outlet (commercial power).
The UPS enters Battery Mode.

Are the same as shown above. ➜When A: Operation is normal. The battery is charged sufficiently.
➜When B: Operation is normal, but the battery is not sufficiently
charged.
Are not the same as shown above. ➜Operation is abnormal. Check the status of lamps and beep and
turn off the Power Switch.
•If the display is No.7 or No.8 of "3. Display and beep when a
failure occurs in equipment" of "4-3 Interpreting a beep and dis-
play" on page 21, take necessary measures and then go back
to (1) on page 15.
•If no Battery Mode is performed and the UPS and the connected
devices stop, insufficient charging of the battery is suspected.
Connect the 100 VAC input plug of the UPS to a wall outlet (com-
mercial power), charge the battery for approximately 6 hours,
and then go back to (4) on page 15.
•If the problem persists after checking the 2 points above, con-
tact us; ____
(6) Connect the 100 VAC input plug to a wall outlet (commercial power) again.
The Power Output Lamp stops blinking and turns on without intervals, and the beeper stops.
(The status is as shown below.)
Checking the operation is now complete.
Installation and connection is now complete.
(Red) Alarm Off
(Green) Power Output On
Beep None

3-1 Charging the battery
When you connect the 100 VAC input plug of this unit to a wall outlet (commercial power), the battery
charging automatically starts regardless of the on/off state of the Power Switch, and it is fully charged
within 12 hours.
●This unit has been charged prior to shipment. However, the backup time becomes shorter when using it for
the first time due to spontaneous discharge. We recommend charging this unit before using it.
●When you do not perform "3-2 Measuring the initial value of backup time" described next, proceed to "4.
Operation."Page 18
3-2 Measuring the initial value of backup time
●Before starting operation for the first time, measure the backup time initial value of the unit in your environ-
ment. You can use it as a guide to check the battery.
See also
"7. Measuring the backup time" →Page 33
3-3 Recharging the battery
The battery is discharged completely when the backup time is measured, so you need to recharge it before
using the UPS.
●You can use connected devices while recharging the battery, but the backup time when a power failure
occurs is shorter until the battery is fully charged.
(If a power failure occurs immediately after the start of charging, backup stops immediately.)

Notes
Before turning off the commercial power, turn off the Power Switch of this unit.
If you cannot turn off the Power Switch, it is recommended to use the UPS
monitoring software to automatically stop the unit in the minimum backup time.
●If you stop commercial power with the Power Switch in the ON position, the Battery Mode starts. If you
frequently use the unit in the Battery Mode after turning off the commercial power, charging and discharg-
ing 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.
