Eachelectrical component is either cabinet mounted orconnected through a ground wire to the cabinet tocomplete the ground. Certain components, such asdefrost timers, may be double insulated and do notrequire a ground wire.Ensure the electrical wall receptacle is of the threeprong type and is properly grounded in accordancewith the National Electrical Code and/or local codes.Compressor ElectricalComponents and CircuitsThe new series of very high efficiency compressor isequipped with all new electrical components consist-ing of a solid state PTC relay with a thermally oper-ated overload protector, and a run capacitor. SeeFigure C1.Figure C1Solid State RelayThe solid state relay has no moving parts. It consistsof a PTC resistor mounted in a plastic case withappropriate terminals. PTC (Positive TemperatureCoefficient) simply denotes a resistor which increasesin resistance as its temperature is increased. The self-heating PTC resistor used in the solid state relay hasthe unique characteristic of changing from low to veryhigh resistance very abruptly, thus serving as an on-off switch. (See Figure C3.)The solid state relay plugs directly onto thecompressor start and run terminals. (See Figure 2.)Relay terminals 1, 2, and 5 are connected within therelay, as are terminals 3 and 6.A run capacitor is connected to relay terminals 2 and3, so it is connected in parallel with the PTC resistor.One side of the 120 VAC power is connected to relayterminal 1. The other side of line is connected to theoverload protector.
