local jurisdiction and codes.
1. Remove the appropriate Main AC/Control Wiring
knock–out plug at back of generator.
2. Install the generator feeder and control wiring
between the generator and inverter or electrical
loads to be powered by the generator per the
applicable NEC codes for the wiring method
selected. For knock–out plug locations (verify
specific transfer wiring and connections per
model), see Figure 2-7.
NOTE: This wiring can be run in the same conduit if the
appropriate insulation rated wire is used.
3. Seal the conduit at the generator in compliance
with any codes.
4. Strip insulation from wire ends. Do not remove
excessive insulation.
5. 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.
