Charging the battery

The battery automatically starts charging when the AC input plug is connected to a wall outlet

(commercial power).

(This occurs regardless of whether the power switch is ON or OFF.)

The charging takes 12 hours to complete.

(The charging time is extended 24 hours per unit when connecting an additional battery unit.)

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.

2-7

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.)

Charge the battery as described in "2-6 Charging the battery."
