If a generator is being installed at this time, proceed 
to step 19. If a generator will not be installed at this 
time, perform steps 14 through 17 to complete the 
pre-wiring project.

14.   Open the outdoor connection box and unplug the 4-pin 

and 2-pin connector. Remove the black, white, red, 
and green wires that lead from the five foot pre-wired 
conduit. Make sure the mating wires from the 30 foot 
conduit are on the connection box terminal lugs (or 
ground screw), re-install all washers and nuts and 
secure them in place.

15.  Remove the lock nut holding the five foot pre-wired 

conduit coupling to the outdoor connection box. Slip 
the lock nut over the wires and plug, then remove 
the conduit from the connection box. Use a knockout 
plug to close off the opening where the conduit was 
removed.

  The external connection box must be locked to 

ensure safety and to discourage tampering.

16.  For pre-existing buildings, switch the service main 

circuit breaker back on to provide utility power to the 
building.

17.  Save the five foot pre-wired conduit for re-installation 

at time of generator installation. At that time, re-install 
the conduit by reversing steps 14 and 15. The ground-
ing strap will also be installed with the generator. Save 
this guide for reference at time of generator installa-
tion.

DANGER

  Be sure the service main circuit breaker is switched 

OFF at time of generator installation.

This completes the pre-wiring portion of the 100 Amp 
Automatic Transfer Switch/Load Center Installation. 
Proceed with step 18 for generator installation.

18.  Place the generator and mounting pad in the location 

prepared in steps one through five.

19.  Attach one end of the grounding strap (No. 12 AWG 

stranded copper wire) to grounding rod, and the other 
end to the grounding lug (located at rear corner of 
unit). Make sure the grounding rod and strap are not 
exposed above ground level (NEC code applies to 
grounding method).

NOTE:

The generator mode switch should be placed in the OFF 
position. Generator main line circuit breaker should be 
switched to the OFF or OPEN position.

20.  Access wiring connections for installation of five foot 

harness at the generator. To gain access to wiring con-

nections and the circuit breaker you must remove the 

cover plate (black) over the control module. Remove 

the two screws retaining the cover plate. Lift the cover 

plate up and towards the front of the generator to 

remove.
