Groundingoftheinvertercircuitboard
WARNING!DISCHARGETHEHIGHVOLATGECAPACITORS
Forabout30secondsaftertheovenisturnedoff,anelectricchargeremainsinthehighvoltagecapacitorsinthe
inverterpowersupplycircuitboard.
Whenreplacingorcheckingparts,removethepowerplugfromtheoutletandshorttheinverteroutputterminal
ofthemagnetronfilamentterminalstothechassisgroundwithaninsulatedhandlescrewdrivertodischarge.
Pleasebesuretotouchthechassisgroundsidefirstandthenshorttotheoutputterminals.
Dischargingthehighvoltagecapacitors
WARNING
Thereishighvoltagepresentwithhighcurrentcapabilitiesinthecircuitsoftheprimaryandsecondary
windings,chokecoilandheatsinkoftheinverter.Itisextremelydangeroustoworkonornearthesecircuits
withtheovenenergized.DONOTmeasurethevoltageinthehighvoltagecircuitincludingthefilamentvoltage
