7.
Connect the vehicle’s breaker panel to the generator output. The generator is pre-
wired to supply 120/240 VAC, with the generator frame bonded to ground. Route
the generator output conduit/wiring to the breaker panel, and carefully cut the
conduit to length without cutting the wire insulation. A conduit connector has been
provided to connect the conduit to the breaker panel. Connect the (4) four
generator output wires to the breaker panel as follows:
Phase A:
Black wire (120 VAC)
Phase B:
Red wire (120 VAC)
Neutral:
White wire
Ground:
Green wire
To completely utilize the generator’s output capabilities, the 120 VAC loads must be
equally divided between the generator’s two main windings. Before wiring the
vehicle, calculate the wattage of each 120 VAC load that will be connected to the
generator. Next, create two groups of loads based on total wattage (add the
individual wattage of each load together). Exchange loads between the two groups
until the total wattage of the two groups is as close as possible to being equal. Wire
the system with one group connected to Phase A (BLACK) and neutral, with the
other group connected to Phase B (RED) and neutral.
ALTERNATE CONFIGURATION: 120 VAC
only: If the application requires 120
VAC only, the generator terminal strip should be configured as depicted below. This
method ensures balanced loading of the generator, fully optimizing the system’s
capabilities. Make the following wire connections at the terminal strip:
a) place one jumper between wire 1 and wire 3.
b) place the second jumper between wire 2 and wire 4.
c) connect the phase wire from the breaker box to either wire 1 or wire 3.
d) connect the neutral wire from the breaker box to either wire 2 or wire 4.
e) connect the ground wire from the breaker box to the green wire.
f) remove red sensing wire from breaker on wire 4
g) connect red sensing wire from wire 4 on breaker to wire 1 on breaker
Note: Command and Control Center will still display 240VAC
