Installation and Owner's Manual

Equipment Description

These new generation transfer switches are intended to operate compatible electrical loads of normal residential installations.The load is connected either to utility power (normal) or home standby power (emergency).The transfer switch monitors utility and generator voltages and will automatically connect to the appropriate source of power.

Major components of the transfer switch are 2 pole contactor switches, control circuit board, fused utility

terminals and interconnecting wiring. The transfer switch is coil-operated from utility or

generator inputs and contains suitable electrical interlock switches to eliminate the possibility of connecting the utility service to the generator output. It has ratings capable of switching generator power into the residence.

The control module circuit board has active circuits sensing utility and generator voltages. It creates a signal for the generator start-up, switch transfer, retransfer when utility is restored and generator cool down periods.The control board also contains red and green lights indicating the power

sources available.
