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will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
of a single battery; three batteries
willgeneratethreetimestheamp/hoursandsoon.
• Thetypeofbatteryyouusetopoweryourinverterisimportant.Batteriesdesignedtostartengineshave

discharge and recharge often. We recommend that you use a different typeof battery that is designed
specifically for this type of load requirement. Deep cycle (marine) batteries generally have the highest
reserve
ratings. They are designed with thicker plates making them capable of withstanding repeated

ConnectionCableGauges
Whenconnectingtheinvertertothepowersourceusethethickestwireavailable,intheshortest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 them
 is fourto six f eet,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mat ch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

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

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