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

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 set-
ting values.

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.)
