Recharging the battery
When you connect the AC input plug of this unit to a wall outlet (commercial power), the battery
charging automatically starts regardless of whether the power switch is ON or OFF, and it is fully
charged within 8 hours.
●
This unit has been charged prior to shipment. However, the backup time becomes shorter when using it
for the fi rst time due to spontaneous discharge. We recommend charging this unit before using it.
●
If you do not perform the initial backup time measurement described below in “2-6 Measuring the initial
value of backup time”, proceed to “3. Operation”.

●
When you measure the backup time initial value of the unit in your environment, this value can be used
as a guide when checking the battery and deciding the UPS monitoring software setting values.
"5. Measuring the backup time"

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.)
