dataprocessingequipment.Ifuncertain,consult your dealer or localrepresentative.
The 1-3kVA@200/208/220/230/240VACisdesigned for usewithathree-wire input (L,N,G).
WARNING
Thebatterycanpresentariskofelectricalshock and high
shortcircuitcurrent.Following precautionsshouldbe
observedbeforereplacing thebattery.
lWear rubber glovesand boots.
lRemoverings,watchesand other metalobjects.

3. System Description
3.1TransientVoltageSurgeSuppression(TVSS)and EMI/FRIFilters
TheseUPScomponents provide surge protectionand filter bothelectromagnetic interference
(EMI)and radiofrequencyinterference(RFI).They minimizeany surge or interferencepresent
inthe utilitylineand keep thesensitiveequipment protected.
3.2Rectifier/PowerFactorCorrection (PFC) Circuit
Innormaloperation,the rectifier/powerfactor correction (PFC) circuit converts utilityACpower
toregulated DC power for usebythe inverter whileensuring thatthe waveformoftheinput
currentused bythe UPSisnearideal.Extracting thissinewaveinputcurrentachievestwo
objects:
lThe utilitypower is used as efficiencyaspossiblebytheUPS.
lThe amountofdistortionreflected on the utilityis reduced.
Thisresultsincleaner power being availabletoother devicesinthe building not being
protected bythe UPS.
3.3Inverter
Innormaloperation,the inverter utilizethe DCoutputofthe power factor correction circuit and
inverters itintoprecise,regulated sinewaveACpower. Upon autility powerfailure,the inverter
receivesitsrequired energy fromthe battery through the DC-to-DC converter.Inbothmodes of
operation,the UPSinverter ison-line and continuously generating clean,precise,regulatedAC
output power.
3.4BatteryCharger
The battery charger utilizes energyfromthe utilitypower and preciselyregulatesitto
continuouslyfloatcharge thebatteries. The batteries are beingcharged whenever the UPSis

3.5DC-to-DC Converter
The DC-to-DC converter utilizesenergyfromthe batterysystemandraisesthe DC voltage to
the optimumoperating voltage forthe inverter.The converter includesboostcircuitwhichis
alsoused asPFC.
3.6Battery
The standard modelincludevalue-regulated, non-spillable,lead acidbatteriesinside. To
maintainbatterydesign life,operatethe UPSinan ambienttemperature of 14-25°C.
3.7DynamicBypass
The UPSprovides an alternatepathfor utilitypower totheconnectedload inthe unlikelyevent
of aUPS malfunction.Shouldthe UPS havean overload,over temperature or anyother failure
condition,the UPSautomaticallytransferstheconnected load tobypass.Bypassoperationis
indicatedbyan audiblealarmand illuminatedamber Bypass LED.
