NOTE: Control wiring must be in accordance with local
jurisdiction and codes.
1. Remove the plug from the field connection box.
2. Remove the two Allen screws to remove the
electrical access panel. The access panel will hang
off of the grounding wire.
NOTE: Do not pull the panel. This will cause the ground
wire to detach from the grounding bus bar.

3. Install the conduit and Main AC and Control Wires
between the generator and the transfer switch
(Figure 6-2). Route the conduit through a NEMA 3
rated external connection box (not supplied).
NOTE: The Electrical access panel is grounded to the
ground bar through a grounding wire. Verify the integrity
of this connection before closing the panel back.
NOTE: This wiring can be run in the same conduit if the
appropriate insulation rated wire is used.
4. Seal the conduit at the generator and in
compliance with any codes.
5. Strip the insulation from the ends of the wires. Do
not remove excessive insulation.
6. To connect the control wires, push down on the
spring loaded connection point with a flat head
screwdriver, insert wire and release.
NOTE: No wire insulation should be in the connection
point; only bare wire.
