The modified sine wave produced by our inverters 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wavef ormwillbeapure
sine wave. Consequently, these meters will not read the RMS modified
sine wa ve 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readingvoltmetersuchas a Fluke87Fluke8060ABeckman4410,

InReview
• Neverattempt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equipme ntyouwishtooperateiscompatiblewith
thecapacityoftheinverter.Donotex ceed800
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inverter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.
