SYSTEM OVERVIEW
This Line-Interactive UPS protects computers, internetworking, and telecom- munications equipment from blackouts, brownouts, overvoltages, and surges. The AVR function continuously corrects the voltages, in-between the brownout and overvoltage transfer points (80 - 164VAC/150 - 271VAC), to a safe usable level. When the UPS is operating in the AVR mode the audible alarm will remain silent and the Boost or the Buck indicator will blink. 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 (80 - 164VAC/150 - 271VAC). NOTE: The input circuit breaker MUST be in the on position for the 208V models. When a blackout, brownout, or an overvoltage condition occurs; the UPS will transfer to the battery mode, the On- Battery indicator will illuminate and the audible alarm will sound once every ten- seconds indicating that the commercial power is lost or unacceptable. When the commercial power returns or is at an acceptable level, the UPS will auto- matically transfer back to the AC normal mode and start recharging the batter- ies. 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 letting the user know that they should save all open files and turn off their computer. When the batteries reach the predeter- mined level the UPS will automatically shutdown protecting the batteries from over discharging. Once the commercial power returns the UPS will automati- cally restart, providing safe usable power to the connected equipment and start recharging the batteries.
TURNING THE UNIT ON/OFF
On / Off / Test Button
Press and release the On/Off/Test Button after one beep to turn the UPS on and supply power to the load. NOTE: The input circuit breaker MUST be in the on position for the 208V models to turn the UPS on. The load is immediately powered while the UPS runs a five-second self test. Press and release the On/ Off/Test Button after one beep to turn the UPS off. NOTE: Turn the input circuit breaker to the off position for the 208V models. The UPS will continue to charge the batteries whenever it is plugged into a wall outlet and there is ac- ceptable AC voltage present.
