CHARGING THE BATTERY
The UPS will charge the internal batteries whenever the UPS is connected to
an AC source and there is an acceptable AC voltage present (90 - 150VAC). It
is recommended that the UPS's batteries be charged for a minimum of 4 hours
before use. The UPS may be used immediately, however, the “On Battery”
runtime may be less than normally expected. Typical battery life is 2 to 3 years.
Environmentalfactors doaffect battery life. High temperatures,poor utilitypower,
andfrequent,short durationdischargeshave anegative impactonbattery life. This
UPShas atemperature compensatingcharger. Asthe ambienttemperature rises
the charger will reduce the voltage to prevent premature failures of the batteries.
NOTE: If the UPS is going to be out of service or stored for a prolonged period of
time, the batteries must be recharged for at least twenty-four hours every ninety
days.
SNMP CARD
Theincluded SNMP Cardis webbasedand isusedfor monitoringand control-
lingtheUPS. See the SNMPCard's Manual forconfiguring and settingupthe

properlywithout thisconnection.
SYSTEM OVERVIEW
This Line-Interactive UPS protects computers, servers, telecom systems, VoIP sys-
tems, security systems, and a variety of electronic equipment from blackouts, brown-
outs, overvoltages, and surges. The AVR function continuously corrects the voltages,
in-betweenthebrownoutand overvoltagetransfer points(90 - 150VAC),toa safe usable
level. When the UPS is operating in the AVR mode the audible alarm will remain silent
andtheAC normalmode indicator willblink. During normalAC operation,the UPSwill
quietlyand confidently protectyoursystem frompower anomalies.
TheUPS will chargethe batterieswiththe UPS inthe onoroff position whenthe UPSis
pluggedintothewall outlet and there isan acceptableACvoltagepresent(90- 150VAC).
ThisUPS has atemperature compensating charger. Astheambient temperature rises
thecharger will reducethe voltagetoprevent premature failuresofthe batteries. When
a blackout, brownout, or an overvoltage condition occurs; the UPS will transfer to the
battery mode, the Battery mode LED will illuminate and the audible alarm will sound
once every five seconds indicating that the commercial power is lost or unacceptable.
Whenthe commercial powerreturnsor is atanacceptable level, theUPSwill automati-
callytransfer back totheACnormalmode and startrecharging the batteries. Duringan
extendedoutagewhen there is approximatelytwo minutesof backuptime remaining the
audiblealarm will soundtwice every fiveseconds. ThisLow Battery Warning is inform-
ing the user that they should save all open files and turn off their computer. When the
batteriesreach the predeterminedlevel theUPSwill automatically shutdownprotecting
the batteries from over discharging. Once the commercial power returns the UPS will
automaticallyrestart,providing safe usablepower tothe connectedequipment andstart
rechargingthe batteries.
TURNING THE UPS ON / OFF
To turn the UPS on: press and hold the On/Off/Test Button until the alarm sounds one
beepand then release. TheUPSwill perform afivesecond internal self-test. Oncethe
