SYSTEM OVERVIEW
ThisLine-InteractiveUPS protectscomputers,servers,telecom systems,VoIPsys-
tems,securitysystems,andavariety ofelectronicequipmentfromblackouts,brown-
outs, overvoltages, and surges. TheAVR function continuously corrects the volt-
ages,in-between thebrownout andovervoltage transferpoints (90- 140VAC),to a
safe usable level. When the UPS is operating in theAVR mode the audible alarm
will remain silent and theAC normal mode indicator will blink. During normalAC
operation, the UPS will quietly and confidently protect your system from power
anomalies.
The UPS will charge the batteries with the UPS in the on or off position when the
UPS is plugged into the wall outlet and there is an acceptableAC voltage present
(90 - 140VAC). When a blackout, brownout, or an overvoltage condition occurs;
theUPSwill transferto thebatterymode, theOnBattery indicatorwill illuminateand
theaudible alarmwill soundonce every tenseconds indicatingthat thecommercial
power is lost or unacceptable. When the commercial power returns or is at an
acceptable level, the UPS will automatically transfer back to theAC normal mode
and start recharging the batteries. During an extended outage when there is ap-
proximately two minutes of backup time remaining the audible alarm will sound
twiceevery five seconds. ThisLow BatteryWarningis informingthe userthat they
shouldsave allopen filesand turnoff theircomputer. When thebatteries reachthe
predetermined level the UPS will automatically shutdown protecting the batteries
fromover discharging. Oncethe commercial powerreturns theUPS will automati-
cally restart, providing safe usable power to the connected equipment and start
rechargingthe batteries.
TURNING THE UPS ON / OFF
To turn the UPS on: press and hold the On/Off/Test Button until the alarm sounds
one beep and then release. The UPS will perform a five second internal self-test.
