SYSTEM OVERVIEW
This Standby UPS protect s computers, servers, telecom systems, V oIP systems,
security systems, and a variety of electronic 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 as long as
the UPS is plugged into the wall outlet and there is an acceptable AC voltage present
(95 - 140V AC). When a blackout, brownout, or an overvolt age condition 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 indicating 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 remaining the audible alarm will sound
twice every five seconds. This Low Battery Warning is informing the user that they
should save all open files, turn off their computer and then turn off the UPS. When
the batteries reach the predetermined level the UPS will automatically shutdown
protecting the batteries from over discharging. Once the commercial power returns the UPS will automatically restart, providing safe usable power to the connected equipment and start recharging the batteries.
