Guardian Technologies 5209 Semi-Automatic Transfer Operation Using Guardian Portable Generator

SECTION 6 - OPERATION OF GENERATOR WITH GENERATOR READY KIT

SEMI-AUTOMATIC TRANSFER OPERATION USING GUARDIAN® PORTABLE GENERATOR

TRANSFER TO GENERATOR POWER SOURCE WHEN UTILITY POWER FAILS

1.Connect ground strap to generator’s grounding lug and to grounding rod.

2.Set the generator’s 50 amp circuit breaker to its OFF (or open) position.

3.Insert the NEMA 14-50 plug (from the power cord that you have installed) into the mating receptacle on the generator control panel.

4.Start the generator.

5.Let the engine stabilize and warm up for a few minutes.

6.Insert the V-type plug (on the DC signal harness you have connected within the external connection box) into the 12 volt DC receptacle on the generator control panel. The insertion of this plug will send a signal to the transfer switch to shift the contactor to the standby position.

7.Set the generator’s 50 amp circuit breaker to its’ ON (or closed) position to send the generator power to the load center in the transfer switch.

Choose a lamp or light fixture located in a frequently occupied area of the house as a signal light to tell you when utility power has returned. This light should be on a utility powered circuit only so it operates independent of the generator.

TRANSFER BACK TO UTILITY POWER SOURCE

When utility power has been restored, you will want to transfer back to that source and shut down the generator. This can be accomplished as follows:

1.Set the generator’s 50 amp circuit breaker to its OFF (or open) position.

2.Remove the V-type plug (on the DC signal harness that was connected within the external connection box) from the 12 volt DC receptacle on the generator control panel. The removal of this plug will send a signal to the transfer switch to shift the contactor back to the utility position and allow the circuits of the home to again be powered by the incoming utility.

3.Let the engine run for a minute or two at no-load to stabilize the internal temperatures.

4.Turn off the generator.

After utilizing the 5 ft. electrical power cord, 5 ft. DC signal harness and ground strap for operation with the GUARDIAN® ULTRA SOURCE portable generator you must disconnect and remove them. Open the external connection box. Remove the fasteners holding the Black, Red, White, and Green wires in place. Remove wires from threaded lugs and from under ground screw. Replace fasteners and ground screw. Loosen the cable clamp and slide the power cord out of the external connection box. Disconnect the 4-pin plug from its mating half within the external connection box. Remove ground strap from the generator’s ground lug and from the grounding rod. Store the power cord, the DC signal harness and the ground strap with your GUARDIAN® ULTRA SOURCE portable generator for future use.
