(3) Connect devices that require backup to the unit’s power supply output receptacle.
A total of up to 750VA (7.5A) or 450W can be connected.
If the unit has an insufficient number of power output receptacles, increase the number of output receptacles
by attaching a separately purchased power strip.
(4) When installation and connection are complete, connect the unit’s AC input plug to a wall outlet (commer-
cial power).
When the AC input plug is connected to a wall outlet (commercial power), the battery automatically starts
charging, taking up to 12 hours to complete.
