The modified sine wave produced by our inverter s has a root mean square (RMS) voltage of 110 volts. The

majorityofACvoltmetersarecalibratedforRMSvoltageandassumethatthemeasuredwaveformwillbeapure

sinewave.Consequently,thesemeterswi llnotreadtheRMSmodifiedsinewave

voltagecorrectlyand,when

measuringtheinverteroutput,themeterswillreadabout20to30voltstoolow.Toaccuratelymeasureofthe

outputvoltageoftheinverter,useatrueRMSrea dingvoltmetersuchasaFluke87Fluke8060ABeckman4410,

Triplet4200oran ymultimeteridentified

as"TrueRMS"

InReview

• Neverat tempttooperatetheinverterfromanypowersourceotherthana12‐voltDCvoltbattery.

• Theinverterisdesignedtobeconnectedtothepowersourcewiththe12voltpowerplug.Donotattemptto

modifythepowercordorplug.

• Whileconnectingthe

invertertothepowersource,makecertainthattheinverterispositionedfarawayfrom

anypotentialsourceofflammablefumesorgases,

• Makecertainthepowerconsumptionoftheapplianceorequipmentyouwishtooperateiscompatiblewith

thecapacityoftheinverter.Donotexceed1500

watts.

• Whenattemptingtooperatebatterychargers,monitorthetemperatureofthebatterychargerfor

approximately10minutes.Ifthebatterychargerbecomesabnormallywarm,disconnectitfromtheinverter

immediately.

• Useonly30ampspadetypefuses.

• Whenoperatingtheinverterwithanautomobileormarinebattery,

starttheengineevery30to60minutes

andletitrunforappro ximat ely10minutestorechargethebattery.

• Intheeventofacontinuousaudiblealarmorautomaticshutdown,turntheinverterOFFimmediately.Donot

res tarttheinverteruntilthesourceoftheproblemhas

beenidentifiedandcorrected.

• Toavoidbatterydrain,alwaysdisconnecttheinverterwhennotinuse.

• Donotexposetheinvertertorainormoisture.

• Avoidplacingthein verternearsourcesofheatorindirectsunlight.

• Whileinuse,makesuretheinverterisproperlyventilated.



• Donotoperatetheinverternearflammablematerials,fumesorgases.
