3.1Transient VoltageSurge Suppression (TVSS) and EMI/FRI Filters
TheseUPScomponentsprovide surge protection and filter bothelectromagnetic
interference(EMI)andradiofrequencyinterference(RFI).Theyminimizeanysurge or
interferencepresentinthe utility line and keep the sensitiveequipment protected.
3.2Rectifier/PowerFactorCorrection (PFC) Circuit
Innormaloperation, the rectifier/powerfactor correction (PFC) circuitconvertsutilityAC
powertoregulated DC power for useby the inverter whileensuring thatthe waveformofthe
input currentusedbytheUPS isnear ideal.Extractingthissinewaveinputcurrentachieves
twoobjects:
lThe utilitypower is used as efficiencyaspossiblebytheUPS.
lThe amountofdistortionreflected on the utilityis reduced.
Thisresultsincleaner power beingavailabletoother devicesinthe building notbeing
protected bythe UPS.
3.3Inverter
Innormaloperation,the inverter utilizethe DC outputofthe powerfactor correction
circuitandinvertersitintoprecise,regulated sinewaveACpower.Upon autilitypower
failure,the inverter receivesitsrequired energyfromthe batterythrough the DC-to-DC
converter.Inbothmodesofoperation,theUPSinverter ison-line and continuously
generating clean,precise,regulatedACoutput power.

5.INSTALLATION
The systemshouldbe installed and wired onlybyqualified electriciansinaccordance
withapplicablesafetyregulations.
NOTICE UPSoperation insustained temperature outside the rangeof15-25°C(59°-77°F)
reduces batterylife.
5.1Unpackingand Inspection
1) Unpackthe packagingand checkthepackage contents. Theshipping package contains:
●1UPS
●1user manual
●2connectors red andwhite）forbatterywith4contacts (6KLand10KL)
●2cableentryprotector (6K and 10K)
2) Inspect the appearanceofthe UPS tosee ifthere isanydamageduring transportation.
Do notturn onthe unitandnotify the carrier anddealer immediatelyifthere isany
damageor lackingofsomeparts.
5.2Connect Input/Output Power
1. Notes forinstallation
1) The UPSmustbeinstalled inalocationwithgood ventilation,far awayfromwater,
inflammablegas and corrosiveagents.
2) Ensure theairvents on the front and rear of the UPS are notblocked. Allowat least
0.5mofspaceon eachside.
3) Condensation towater dropsmayoccur iftheUPS isunpackedinaverylow
temperature environment.Inthiscaseitisnecessarytowaituntilthe UPSisfully
dried inside outbefore proceeding installation anduse.Otherwisethere are hazards
of electricshock.
2. Installation
Installationand wiring mustbe performedinaccordancewiththelocalelectriccode and
the following instructions byprofessionalpersonnel.
For safety,pleasecutoff the mainspower switchbefore installation.Open the battery
breaker for longbackup timemodel( L”model).
1) Open the terminalblock coverlocated on the rear paneloftheUPS,pleasereferto
the appearancediagram.
2) For 6k(L) UPS, itis recommended toselect the UL1015 10AWG(6mm2)wire or other
insulated wire whichcomplieswithAWGStandard for the UPSinputand output
wirings.
3) For10k(L)UPS,itisrecommendedtoselecttheUL10158AWG(10mm2)wire or

NOTICE Do notusethe wall receptacleasthe inputpower sourcefor the UPS, asits rated
currentis lessthan theUPS’smaximuminputcurrent. Otherwisethereceptaclemay beburned
and destroyed.For thelong backup timemodes, makesure thatthe capacityofbatteriesis
larger than 24AHtoavoidover charging.
5) For 6-10K, connect the inputand outputwirestothe corresponding inputand output

10）Pleaseinstall the output breaker between the outputterminaland the load,and the
breaker shouldwithleakage current protectivefunction if necessary.
11) Toconnect the load withtheUPS, pleaseturn offallthe loadsfirst, then performthe
connection and finally turn on the loads one byone.
12) No matter the UPSisconnected tothe utility power or not, the outputof the UPSmay
haveelectricity.The partsinsidethe unitmaystill havehazardousvoltage after
turning offthe UPS.Tomakethe UPS haveno output, power offtheUPS, and then
disconnecttheutilitypower supply.
13) Suggestcharging the batteries for 8hoursbefore use.After connection,turn the input
breaker inthe ON”position,the UPS will charge the batteries automatically.You can
alsousethe UPSimmediatelywithoutcharging the batteriesfirst, butthe backup
timemaybe lessthan thestandard value.
14) If itisnecessarytoconnecttheinductiveload suchasamonitoror alaser printer to
