2.1Unpacking and inspection
1.Notes forinstallation
1)The UPS mustbe installed inalocation withgood ventilation,far
awayfromwater,inflammablegasand corrosiveagents.
2)Ensurethe airventson the frontand rearofthe UPS arenotblocked.
Allowatleast0.5mofspaceon eachside.
3)Condensation towaterdropsmayoccurifthe UPS isunpacked ina
verylowtemperatureenvironment. Inthiscaseitisnecessaryto
waituntil the UPS isfullydried inside outbeforeproceeding instal-
lation and use.Otherwisetherearehazardsofelectricshock.
2.Installation
Installation and wiring mustbe performed inaccordancewiththe local
electriccode and the following instructionsbyprofessionalpersonnel.
Forsafety,pleasecutoff the mainspowerbreakerbeforeinstallation.
The batterybreakeralsoneedstobe cutoff ifitisalong backup time
model(“S”model).
1)Open the terminalblock coverlocated on the rearpanelofthe UPS,
pleaserefertothe appearancediagram.
2)ForC6K(e)/C6KS(e)UPS,itisrecommended toselectthe UL1015
10AWG(6mm2)wireorotherinsulated wirewhichcomplieswith
AWGStandardforthe UPS inputand outputwirings.
1)Unpack the packaging and check the package contents.The ship-
ping package contains:
AUPS
Ausermanual
Acommunication cable
Abatterycable(forC6KS(e)/C10KS(e))
2)Inspectthe appearanceofthe UPS tosee ifthereisanydamage
during transportation.Donotturnon the unitand notifythe carrier
and dealerimmediatelyifthereisanydamage orlacking ofsome
parts.

Note:you mustmakesurethatthe inputand outputwiresand the input
and outputterminalsareconnected tightly.
5)The protectiveearthground wirereferstothe wireconnection be-
tween the equipmentwhichconsumeselectro-equipmentand the

7)Pleaseinstall the leakcurrentprotectivebreakeratthe outputpower
distribution panelofthe UPS ifnecessary.
8)Toconnectthe load withthe UPS,pleaseturnoff all the loadsfirst,
then perform the connection and finallyturnon the loadsone byone.
9)Nomatterthe UPS isconnected tothe utilitypowerornot, the output
ofthe UPS mayhaveelectricity.The partsinside the unitmaystill
havehazardousvoltage afterturning off the UPS.Tomakethe UPS
haveno output, poweroff the UPS,and then disconnectthe utility
powersupply.
10)Suggestcharging the batteriesfor8hoursbeforeuse.After
connection,turnthe inputbreakerinthe “ON”position,the UPS will
charge the batteriesautomatically.You can alsousethe UPS im-
mediatelywithoutcharging the batteriesfirst, butthe backup time
maybe less than the standardvalue.
11)If itisnecessarytoconnectthe inductanceload suchasamonitor
oralaserprintertothe UPS,the start-up powershouldbe used for
calculating the capacityofthe UPS,asitsstart-up powerconsump-
tion istoo bigwhen itisstarted.
Afterhaving completed the installation,makesurethe wiring iscorrect.

mentistocharge the UPS regularlyinordertomaximizethe expected
lifeofthe battery.When being connected tothe utilitypower,whetherthe
UPS isturned on ornot, the UPS keepscharging the batteriesand also
offersthe protectivefunction ofovercharging and overdischarging.
The UPS shouldbe charged onceevery4to6monthsifithasnotbeen
used foralong time.
Inthe regionsofhotclimates,the batteryshouldbe charged and dis-
charged every2months.The standardcharging timeshouldbe atleast
12 hours.
Undernormalconditions,the batterylifelasts3to5years.Incaseifthe
batteryisfound notingood condition,earlierreplacementshouldbe
made.Batteryreplacementshouldbe performed byqualified personnel.
Replacebatterieswiththe samenumberand sametype ofbatteries.
Donotreplacethe batteryindividually.All the batteriesshouldbe re-
placed atthe sametimefollowing the instructionsofthe batterysupplier.
Normally,the batteriesshouldbe charged and discharged onceevery
4to6months.Charging shouldbeginafterthe UPS shutsdownauto-
maticallyinthe courseofdischarging,the standardcharging timefor
