SYSTEM OVERVIEW

This UPS protects computers, internetworking, security, and telecommunica-

tions equipment from blackouts, brownouts, overvoltages, and surges. During

normal AC 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 acceptable AC voltage

present (100 - 140VAC). When a blackout, brownout, or an overvoltage condi-

tion occurs; the UPS will transfer to the battery mode, the On Battery indicator

will illuminate and the audible alarm will sound once every five seconds indicat-

ing that the commercial power is lost or unacceptable. When the commercial

power returns or is at an acceptable level, the UPS will automatically transfer

back to the AC normal mode and start recharging the batteries. During an

extended outage when there is approximately two minutes of backup time re-

maining the audible alarm will sound twice every five seconds. This Low Bat-

tery Warning is letting the user know that they should save all open files and

turn off their computer. When the batteries reach the predetermined level the

UPS will automatically shutdown protecting the batteries from over discharg-

ing. Once the commercial power returns the UPS will automatically restart,

providing safe usable power to the connected equipment and start recharging

the batteries.
