SYSTEMOVERVIEW
ThisLine-Interactive 1U Rackmount model UPS protects internetworking and
telecommunicationsequipment from blackouts, brownouts, overvoltages,and
surges. TheAVR function continuously corrects the voltages, in-between the
brownoutandovervoltagetransferpoints(85 -150VAC), toasafe 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 normalAC opera-
tion, the MINUTEMAN UPS will quietly and confidently protect your system
frompoweranomalies.
TheUPS willcharge thebatteries withthe UPS in the onor offposition aslong
astheUPSisplugged intothewalloutletand thereisanacceptableACvoltage
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
outagewhenthere isapproximately two-minutesofbackup timeremaining the
audiblealarmwillsoundtwiceevery five-seconds. This LowBatteryWarningis
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
thecommercialpowerreturns theUPSwillautomatically restart,providingsafe
usablepower tothe connected equipmentand startrecharging the batteries.

Although battery system voltages are only 24VDC the battery
system can still present a risk of electrical shock. These batter-
ies produce sufficient current to burn wire or tools very rapidly,
producing molten metal. Observe these precautions when re-
placingthe batteries:
1. Remove watches, rings, or other metal objects.
2. Use hand tools with insulated handles.
3.Wear protective eyegear (goggles),rubber glovesand boots.
4. Do not lay tools or other metal parts on top of batteries.
5. Disconnect the charging source prior to connecting or
disconnecting the battery terminals.
6.Determine if thebattery is inadvertentlygrounded. If the bat-
tery is, remove the source of the grounding. Contact with any
part of a grounded battery can result in an electrical shock.
The likelihood of such shock will be reduced, if such grounds
areremoved during installationand maintenance.
