3. Conclusion: The reserve power of a battery with a 150 reserve minutes rating is sufficient to satisfy the

continuousloaddemandplacedontheinverterforamaximumofaboutonehour.(45amps/hour‐ampdraw

=1hour).

Note:

• Whentheinverterwi llbeoperatingapplianceswithhighcontinuousloadratingsforextendedperiods,it

isnotadvisabletopowertheinverterwiththesamebatteryusedtopoweryourcarortruck.Ifthecaror

truckbatteryisutilized foranextendedperiod,itispossiblethat

thebatteryvoltagemaybedrainedto

thepointwherethebatteryhasinsufficientreservepowertostartthevehicle.

• It may be advisable to operatethe  inverter from a bank ofbatteries of the same type ina "parallel"

configuration.Twosuchbatterieswillgeneratetwicetheamp/hours

specifically for thistypeof loadrequirement. Deepcycle(marine) batteries g enerally havethehighest

ConnectionCableGauges

Whenconnectingtheinvertertothepowersourceusethethickestwireavailable,intheshortes tlengthpractical.

Iftheinverterandthebatteryarepositionedwithinfourfeetofeachother,aminimumof#4gaugewireshould

beusedtomaketheconnections.Whenthedistancebetweenth em

isfourtosixfeet,aminimumof#2gauge

wireis required. When separated bymorethan six feet, always use#0 gauge wire.Seethe last pageof this

manualforrecommendations.

ConnectingYourInverter

1. MakesuretheON/OFFrockerswitchlocatedonthefrontpaneloftheinverterisintheOFF(0)position.

2. Connectthecablestothepowerinputterminalsattherearoftheinverter.Makesuretomatchthenegative

(Black)terminalonthe12voltpowersourcefirst.

Thenrepeatthisprocedurewiththepositive(Red)terminal

connectingawiretothepositiveterminalofthe12vvoltpowersource.Makesurethatyouhaveagood

secureconnection,butdonotovertightenthesescrews.

Note

• Looseconnectionscanresultinaseveredecreaseinvoltage,whichmaycausedamagetothewiresand

insulation.

• Failuretomakeaproperconnectionbetweentheinverterandthepowersourcewillresultinreverse

polarity.Reversepolaritywillblowtheinternalfusesintheinverterandmay

causepermanentdamageto

theinverter.Damagecausedbyreversepolarityisnotcoveredunderthewarranty.

• MakingtheconnectionbetweenthePositiveterminalsmaycauseasparkasaresultofcurrentflowingto

charge capacitors within the inverter. This is a normal occurrence. Due to the possibility

of sparking,

however,itisextremelyimportantthatboththeinverterandthe12voltbatterybepositionedfarfrom

any possible source of flammable fumes or gases. Failure to heed this warning could result in fire or

explosion.
