Anydamages caused by using incorrect RS232 cable will be
outsideof our warranty scope. If you are notsure whichoneis
correct RS232 cable, pleasepurchasethe correct RS232
cable fromus directly.
2-2-4Connectchassis ground terminalto earth or tovehiclechassisusing# 8AWG
wire.
WARNING!
Operationof the unitwithout aproper ground,c
onnection may
resultin anelectrical safety hazard.
WARNING!
ShockHazard.Before proceedingfurther,carefully checkthe
unitis NOTconnectedto any batteries,
andthatall wiring is
disconnectedfrom anyelectrical
sources. Donot connect the
output terminals of theunit toanincomingAC source.

2-3 Installation
Where to install：
The unit shouldbe installedin a locationthatmeets the following requirements.
2-3-1Dry Do not allow water to drip or splash onthe unit.
2-3-2Cool Ambient air temperatureshould be between-20°C and 50°C, thecooler
the better.
2-3-3Safe Do not install in abattery compartment or other areaswhere flammable
fumesmay exist,such asfuelstorage areasor engine compartments.
2-3-4Ventilated Allow at least 3 inch ofclearance aroundthe unit for airflow. Ensure
theventilationopeningson the rear and bottomof the unit are not obstructed.
2-3-5Dust-free Donot install the unitin adusty environments where are dust,wood
particles orotherfilings/shavings.
Thesedustscan bepulled intothe unit when thecoolingfanisoperating.
2-3-6Close to batteries Avoid excessive cable lengthsbut donotinstall the unitin the
same compartmentasbatteries.
Usethe recommendedwirelengths and sizes (seesection2-6).
Also donot mount the unit where it will be exposedto the gases produced bythe
battery. These gasesarevery corrosiveandprolonged exposurethat will damage
the unit.
2-4 QuickHook –Up and Testing
2-4-1Unpackand inspect theunit, check to seethattheswitchintheOFF position.
2-4-2Connect the cablestothe unit terminals ontherearpanel ofunit.
The red terminal is positive (+)and blackterminalisnegative (-).
Insertthecables into the terminals and tighten relative nut toclamp the wires
securely.
WARNING!
You mayobserve asparkwhenyoumake this connection
sincecurrent may flowto charge capacitors inthe unit.
Do notmakethis connectioninthe presence of f
lammable
fumes. Explosion or fire mayresult.

8
WARNING!
Makesure allthe DC connections aretight (torqueto9-
10
ft-lbs, 11.7-
13Nm). Looseconnectionswilloverheatand could
resultin apotentialhazard.
2-4-3Before proceedingfurther, carefully check that cable you have just connected
negativeterminal of unit to thenegative outputpower source.
2-4-4Connect the cable fromthe negative terminal of the unitto thenegativeterminal of
the power source. Make asecureconnection.
2-4-5Set thepowerswitch to the ON position; you will hear the“bi-bi-bi”sound.At the
same time,thedisplayshows the word“ASIAN”for two times. After that,you will
hear the continuoussoundfrom internal alarm.Then, theAC voltage shows on
the display. Itmeans the devicehasdone theoperation.
2-4-6Set thepowerswitch to the OFF position; thedevice shutsdown completely.
2-4-7Please use apower meter to accurately measure thetrueoutputR.M.S. voltage
of theunit.
Our companyuses a power meter suchasIDRC CP-350or ABM2019to
measureourproduct.
CAUTION!
Reverse polarity connection willblow a fuse inunit andmay
permanentlydamagethe unit.
Damage causedby reversingpolarityconnectionisnot
covered by our warranty.
WARNING!
You mayobserve asparkwhen yo
umakethisconnection
since currentmayflowto chargecapacitorsinthepower
inverter.
Donot makethisconnection in thepresenceof
flammable
fumes.Explosionor fire may result.

2-5 AC Safety Grounding
During the ACwiringinstallation,AC inputandoutput groundwiresareconnectedtothe
unit. TheAC input ground wire mustconnect totheincoming groundfrom your AC utility
source.
TheAC output groundwire shouldgoto the grounding point foryour loads(for example,
adistribution panel ofbus chassis).
2-5-1Neutral grounding (GFCI’s)
2-5-1.1 120V Models:
The neutral conductorof theAC output circuit of the unitisautomatically
connectedto the safety groundduring unitoperation. This conformsto
national electrical code requirementsthatseparatelyderivedAC sources
(such as inverterandgenerators)havetheir neutral conductorstied to
ground in thesame way that the neutralconductor fromthe utility is tied
to ground attheGFCIbreaker panel.For modelsconfigured witha
transferrelay,whileAC utilitypower is presenting andtheinverter isin
bypass mode, this connection(neutral of theunit’sAC output toinput
safety ground)isnot present sothattheutilityneutral is only connected
to ground atyour breaker panel,as required.
2-5-1.2 230V Models:
Thereis noconnection made inside the unitfrom either the line or
neutral conductorto thesafetyground.
GroundFault Circuit Interrupters (GFCI’S):
Installations in Recreational Vehicles (for North Americanapprovals) will require
GFCI protection ofallbranchcircuit connectedto theAC output of thehardwire
terminalequipped unit. In addition, electricalcodesrequireGFCIprotection of
certain receptacles inresidential installations.Whilethepure sine waveoutput of
the unit is equivalent tothe waveform provided byutilities, compliance with UL
standards requires us totest andrecommend specificGFCI. Our companyhas
tested thefollowing GFCI-protected 20Areceptaclesand foundthat they
functioned properly whenconnected totheoutput of the unit.
WARNING!
Do not operate the unitwithout connecting it toGround.
Electricalshockhazard may result.

2-6 Making DC Wiring Connections
Follow thisprocedureto connectthe battery cablesto the DC inputterminalson theunit.
Your cablesshouldbeasshort as possible (ideally,less than10feet/3 meters)and
large enoughto handle the requiredcurrentinaccordance withtheelectricalcodes or
regulations applicable toyour installation.
Cables that arenot anadequate gauge (too narrow) or are toolong will cause decreased
unit performancesuchaspoor surge capability and frequentlow inputvoltage warnings
andshutdowns. These low input voltage warningsare due to DC voltage drop acrossthe
cablesfrom theunit tothebatteries.
Thelonger andnarrower these cables,thegreater the voltagedrop.
WARNING!
The installation of a fusemust be on positive cable.
Failure toplacea fuseon “+ “cablesrunningbetweenthe
unit andbattery maycause damageto the unitandwillvoid
warranty.
Increasing your DCcable size will help improve the situation.
Our companyrecommends thefollowing cablesfor optimumunit performance (apply both
120V and 230V versions.

2-7 Operation
To operate theunit, turn it on using the ON/OFFswitchonthe front panel.
The unit isnow ready to deliverAC power to your loads.
If you areoperating severalloadsfrom the unit, turn them onseparatelyafter the unithas
been turnedon.
This willensurethattheunitdoesnothavetodeliver the startingcurrents foralltheloads
atonce.
2-7-1Controls and indicators
The ON / OFF switch turns the controlcircuit in the unit on and off.
The inverter operatesfrom aninput voltage range:
10.0 to 16.0 VDC for 12V models
20.0 to 32.0 VDC for 24V models
42.0 to 62.0 VDC for 48V models

2-7-8Over Voltage Protectionindicator:(OVP)
The over voltage indicator indicates that the power inverter hasshut itself down
becauseits input voltage exceeded12V /24V/ 48VDCversion.(Ref.point 2-7-1)
2-7-9Under Voltage Protection indicator: (UVP)
The under voltage indicator indicates thatthe power inverter hasshutitselfdown
becauseits input voltage fellbelow 12V / 24V / 48VDC. (Ref.point 2-7-1)
2-7-10 Over TempProtectionindicator: (OTP)
The over temp indicator indicates thatthe power inverter hasshut itself down
becauseits temperaturehasbecome overheated. The power inverter may
overheat because it has beenoperated atpower levels above itsrating, or
becauseit hasbeen installedin a locationwhichdoesnot allow it todissipate heat
properly.The power inverter will automatically backup, once it has cooled off.
2-7-11 Over Load Protection indicator: (OLP)
The overloadindicator indicatesthat the power inverter has shut itself down.
Whenoutputvoltageover itscontinuousvoltage,then mustreturn tooperate
manually.
2-8 Cooling Fan Working Code
Cooling fan ofinverter isthroughdetectingoutputpower andover temperaturesituation
towork.
Whenstarttoturn on theinverter andoutput power under 300W, the cooling fandoesnot
startrunning.It complies with savingenergy sourcesrequirement. Until, output power is
upto 300W, thecoolingfanwillstarttowork inorder to drop the inner temperature.
Ifthe ventilation openingisobstructed, the inverter will enter OverTemperature Protection
mode(OTP). The cooling fan will continue working todrop the innertemperature. When
the temperature comes down to normal situation, the inverter will turn on automatically.
