SYSTEM OVERVIEW
This Line-Interactive 1U Rackmount model UPS protects internetworking and
telecommunications equipment from blackouts, brownouts, overvoltages, and
surges. The AVR function continuously corrects the voltages, in-between the
brownout and overvoltage transfer points (85 - 150VAC), 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 opera-
tion, the MINUTEMAN 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. 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 re-
turns 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
letting the user know that they should save all open files and turn off their
computer. When the batteries reach the pre-determined 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.
