Charging the battery
The battery automatically starts charging when the unit is connected to a commercial power
source.
(This occurs regardless of whether the power switch is ON or OFF.)
The charging takes 8 hours to complete.
The unit was charged before shipment, but it may have self-discharged during shipment, resulting
●
in a reduced backup time. We recommend charging the unit before use.
If you do not perform the initial backup time measurement described below in "2-7 Measuring the
●
initial value of backup time", proceed to "3. Operation. → Page 24"

Measuring the initial value of backup time
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.

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 "2-6 Charging the battery."
