SERVICE OF DOUBLE-INSULATED APPLIANCES
In a double-insulated controller, two systems of insula on are provided instead of grounding. No equipment
grounding means is provided in the supply cord of a double-insulated controller, nor should a means for
equipment grounding be added to the controller. Servicing a double-insulated controller requires extreme
care and knowledge of the system, and should be done only by qualifi ed service personnel. Replacement parts
of a double insulated controller must be iden cal to the parts they replace. A double insulated controller is
marked with the words "DOUBLE INSULATION" or "DOUBLE INSULATED". The symbol for double insula on
may also be marked on the appliance.
