Safetyrules
Evenif notconnected tomainpower, high voltage maystillpresentsat UPS outlets.
If the externalbattery cordorpowercordneedstobe replaced, pleasecontact ourservicestation or
franchiserforreplacing toavoidfiredisastercaused byinsufficientcapacityof suchitems. Don't disposeof
battery orbatteriesgroup inafire, otherwise, itcan causeexplosion and harmtopeople.Don't open the
battery ordothe battery damage,forthe liquidspilled frombatteryisstronglypoisonousand do harmful to
body.
Pleaseavoidshort-circuit between battery anode and cathode; otherwise, thiswillcauseelectricshock or
fire.
Don't dismantlethe UPS cover,thereisdangerofelectricshock.
Don’t touchbatteries. Batteriesarenotisolated withthe input circuit,thereishigh voltage between the
battery terminalsand ground.
Don’t connect withthe electricequipment suchasblower, heater, drillingmachineetc.Theymaydamage
the UPS.

2.1. Unpackingandinspection
1). Unpack the packaging and checkthe package contents.The shipping package contains:
lAUPS
lAusermanual
lAcommunication cable
lAbatterycable(for “L”modelsonly)
2).Inspectthe appearanceoftheUPStosee ifthereisanydamageduring transportation.Donotturnon
the unitand notifythe carrierand dealerimmediatelyifthereisanydamage orlacking of someparts.
3). Check if the equipmentisjust what you wanted topurchase. You can affirmthrough inspectingthe
modelnumberon backpanelof the equipment.
2.2. Safetynotes
1). Keep good aircirculation around UPS and farawayfromwater,flammablegasand corrosive.
2). Don't placeUPSon theslope and thereshouldkeep good aircirculation between in-vent onfrontpanel
bottomand fanoutventon back panel.
3). The environmenttemperaturearound UPSshouldkeep inarange of 0℃~40℃.
4). Therewillbe phenomena ofcondensing ifthe equipment isdismantled orinstalled underlow
temperature.The equipmentcan'tbe installed unless itisfull dry at internal and external ofthe equipment,
otherwise, therewillbe dangerofelectric.
5). The socketthat suppliespowertoUPS shouldbe placed nearthe UPS and easy.

2.4. Inputandoutputpower chordsandprotective earth groundinstallation
2.4.1. Notesforinstallation
1)The UPSmustbe installed inalocation withgood ventilation,farawayfromwater,inflammablegas
and corrosiveagents.
2)Ensurethe airventson the frontand rearof the UPSarenotblocked.Allowatleast0.5Mof spaceon
eachside.
3)Condensation towaterdropsmayoccurif theUPSisunpacked inaverylowtemperatureenvironment.
Inthiscaseitisnecessary towaituntilthe UPSisfullydried inside outbeforeproceeding installation and
use. Otherwisetherearehazardsofelectricshock.
2.4.2.Installation
Installation and wiring mustbe performed inaccordancewiththe localelectriccode and the following
instructionsbyprofessionalpersonnel.
Forsafety, pleasecut offthe mainspowerswitchbeforeinstallation.The battery breakeralsoneedstobe
cut off ifit isalong backup timemodel(“L”model).
1)Open the terminalblockcoverlocated on the rearpanelofthe UPS,pleaserefertothe appearance
diagram.
2)ForH6KS(L)UPS,itisrecommended toselectthe UL1015 10AWG(6mm2)wireorotherinsulatedwire
whichcomplieswithAWGstandardforthe UPSinput and output wirings.
The protectiveearthground wirereferstothe wireconnection between toe equipmentwhichconsumes
electricequipment and the ground wire. The wirediameterofprotectiveearthground wireshouldbe atleast
asabovementioned foreachmodeland green wireofgreen wirewithyellowribbon wireisused.
1)Afterhaving completed the installation, makesurethewiring iscorrect.
2)Pleaseinstallthe leakcurrentprotectivebreakeratthe outputpowerdistribution panelofthe UPS if
necessary.
3)Toconnectthe load withthe UPS,pleaseturnoffallthe loadsfirst, then performthe connection and
finallyturnon the loadsone byone.
4)No matterthe UPS isconnected tothe utilitypowerornot, the outputof the UPS mayhaveelectricity,
the partsinside the unitmaystill havehazardousvoltage afterturning offtheUPS.Tomakethe UPShave
no output, poweroff the UPS,and then disconnect the utilitypowersupply.

5)Suggestcharging the batteriesfor8hoursbeforeuse.Afterconnection,turnthe inputbreakerinthe
“ON”position,the UPSwillcharge the batteriesautomatically.You can alsousethe UPS immediately
without charging the batteriesfirst, butthe backup timemaybe less than the standardvalue.
6)Ifitisnecessary toconnectthe inductanceload suchasamonitororalaserprintertothe UPS,the
start-up powershouldbe used forcalculating the capacityoftheUPS,asitsstart-up powerconsumption is
too bigwhen it isstarted.

2.5.Operatingprocedure forconnectingthelongbackup time modelUPS withtheexternalbattery
1).The nominalDC voltage of externalbattery pack is240VDC.Eachbattery pack consistsof 20 piecesof
12Vmaintenancefree batteriesinseries.Toachievelongerbackup time,itispossibletoconnect
multi-battery packs, butthe principleof “sameVoltage,sametype”shouldbe strictlyfollowed.
2).The connectorofthe externalbattery cableisused toplug intothe externalbatterysocket of the UPS
The otherend of the externalbattery cableismade ofthree open wireswithring terminalstoconnectwith
the externalbatterypack(s).The procedureofinstalling battery bankshouldbecompliedwithstrictly.
Otherwiseyou mayencounterthehazardousofelectricshock.
A.ADC breakermust be connected between the batterypack and the UPS.The capacityof breakermust
be not less than the dataspecified inthe general specification.
B. Set the batterypack breakerin “OFF”position and connect the 20 piecesof batteriesinseries.
C.You mustconnectthe externalbattery cabletothebattery first, ifyou connectthe cabletothe UPS
first,you mayencounterthe hazardousofelectricshock. The positivepoleofthe batteryisconnected tothe
H10KL/three-phaseH10KLinparallelwithblue and brownwires;the negativepoleofthe battery is
connected tothe H10KL/three-phaseH10KLinparallelwithblackand whitewires;the green and yellow
