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.

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.)

Charge the battery as described in "3-1 Charging the battery."
Preparation for starting operation is now complete.
