SEMI-AUTOMATIC TRANSFER OPERATION USING GUARDIAN
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.
SECTION 6 - OPERATION OF GENERATOR WITH GENERATOR READY KIT
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
generator for future use.
