1. SafetyInstructions
1.1Transport
PleasetransporttheUPS systeminitsoriginalpacking carton(to
protect it against damage due toshockand impact).
1.2Set-up
AscondensationmayoccuriftheUPS ismoveddirectlyfromcoldto
warmenvironment, andinorder todrytheUPS beforeinstallation,
pleaseallowacclimatization timeof at least twohours.
Donotinstall the UPS systemnear watersourcesor indump
environment.
Donotinstall the UPS whereitcouldbeexposedtodirectsunlightor
near heat.
Donot blockoff the ventilation openingsof the UPS cabinet.
1.3Installation
Donotconnectappliancesoritemsofequipment,whichmayoverload
the UPS (suchaslaser printers), tothe output of the UPS.
Placethecablesinsuchawaythatno onecanstep onortripover
them.
Donotconnecthomeappliances,suchashair-dryers,totheoutputof
the UPS.
ThisUPS can be operated byanyindividualwithno previous
experience.
Connect the UPS onlytoan earthed shock-proof socket outlet.
Thesocketoutlet, towhichtheUPS isconnected,mustbeeasily
accessibleand closetothe UPS.
Pleaseread the following user manual andsafetyinstructionsbefore
installing this unit and starting it up.

UseonlyVDE-tested,CE-markedcable(asthepowercableofyour
computer) toconnect the UPS tothe building socket outlet.
UseonlyVDE-tested,CE-markedpowercablestoconnecttheloads
tothe UPS.
ThisUPS isan operator installable.
When installingtheequipment, itshouldbeensured thatthesumof
the earthleakage currentfromthe UPSand the load connected toit
must not exceed 3.5mA
1.4Operation
Do notremoveorunplug theinputcord whentheUPS isturnedon.

Caution riskofelectricshock.Evenafterthe UPS hasbeen
disconnectedfromthemainssupply(buildingsocketoutlet),
dangeroushigh voltagesare still existing inside the UPS.
Beforecarryingoutanytype ofservicingandrepair,disconnectthe
mainssupplyandthebatteries.Verifythatnohazardousvoltageexists
on the terminalsof the capacitors.

Onlypersons,adequatelyfamiliarwithbatteriesand withthe required
precautionarymeasuresmyreplacethe UPSbatteries,unqualified
personsmust not dealwithbatteries.

measures, shouldbe observed:
-Removewatches, rings, or other metalobjects.
-Usetoolswithinsulated handles.
Replacethe batterieswiththe samenumber and type,astheoriginally
installed ones.
Donot disposeof the batteriesinafire. Batteriesmayexplode.
Donot open or destroythe battery. Released electrolyteisharmfulto
skinand eyes. It maybe toxic.
When replacing afuse, useonlyone of the sametype and the same
current and voltage ratings, asthe originalfuse.
Donot dismantlethe UPS system.

7. Setting The UPS Parameters
The frontpanelbuttonswitchesare used tosetthe UPSoutputvoltage and
frequencyandtodisableorenablethe bypass circuit. TheUPS output
voltage canbesetto208VAC,220VAC,230VACor240VAC.TheUPS
outputfrequencycanbesetto50Hz.or 60Hz.The UPS bypass circuitcan
be set toenableor disablestate.
NotethattheseparameterscanbesetonlywhentheUPS isinthe bypassor
inthe no-output mode.
WhiletheUPS isinthe bypass orintheno-outputmode, ifthe"Select"button
ispressedfor morethan onesecond,aflickering blackround dotwill be
showninfrontofthe"208V"ontheLCD.Ifthe"Select"buttonisagain
pressed continuously,theflickeringdotwill movetothefrontofthe"220V",
"230V","240V","50Hz","60Hz","Bypass Disable"and "Bypass Enable"
cyclically.
Toselectanyofthesepossiblechoices,press the"Enter"buttonformore
than one second.
The outputvoltage andfrequencyoftheUPS will be changed tothe selected
value after the UPS isturned on, bypressing the "ON"button.
Ifthe"BypassEnable"wasselected,The UPS will turn tobypass mode,in
severalseconds.Whileif"Bypass Disable"wasselected,theUPS will turn to
"NoOutput"mode.
The followingfiguresshowthe stepsrequired tochange theUPS output
voltage from220Vto230V.

Step 1.After pressingthe “Select”button,for more thanonesecond,one
flicking round dot will appear infront of the “208Vac”.
Step 2.Pressingthe “Select”buttontwiceagain,theflickingrounddot
will movetothe front of the “230Vac”
