Appendix C - Powermaster™ Load Controller Installation And Operationa Testing - Generac Power Systems 7 kW NG Installation Manuallines

15. Shut OFF utility power again to automatically start the
generator. When power has transferred to the generator, close
each of the breakers in the distribution panel one at a time
until the generator has accepted the entire load.
16. With the generator carrying the entire load, recheck gas
pressure to verify that it's at the same level it was before the
generator was started.
NOTE: Even if the generator is running smoothly at this point, a
drop in gas pressure indicates that the supply is barely adequate
to supply the generator's needs. Changes in the generator load,
or additional gas demand by other appliances may affect the
generator's performance. Verify gas pressure and pipe sizing.
Unhook the manometer and reinstall the port plug.
17. Switch the utility breaker ON to restore utility power to the
home.
18. The generator will continue to run to allow the engine to cool
down, then shut itself off.
19. Shut OFF utility power again. The generator should start and
the entire priority load should transfer to the generator.
20. Close the main breaker to restore utility power and allow the
engine to cool down and shut itself off.
Operational tests are now complete. Refer to – Setting the
Automatic Exercise Function to complete the installation.

CONTROLLER INSTALLATION AND
OPERATIONAL TESTING
1. The PowerMaster load controller should be mounted as
close to the main distribution panel as possible to avoid
splicing. Refer to the instructions and wiring diagram in
the PowerMaster Technical Manual before beginning the
installation.
2. After making sure that all power supplies are shut off, remove
the power leads from the 240 volt, 2-pole breaker that
controls the selected appliance.
