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.

INSTALLATION

Unpacking

Delivery Inspection

After removing the carton, carefully inspect the transfer

switch components for any damage that may have occurred

during shipment.

IMPORTANT: If loss or damage is noted at time of

delivery, have the person(s) making delivery note all damage

on the freight bill and affix his signature under the

consignor's memo of loss or damage. If loss or damage is

noted after delivery, contact the carrier for claim

procedures. Freight damaged parts are not warranted.
