Voltage Sensing for Genset
Start. Use either this signal or
2-wire start signal for Genset
Start Signal.
• For power output connection (L1, L2, Neutral (N), and Ground), refer to the National Electric and local codes.
• For communication wires use #18 AWG [1mm
2
] twisted pair conductors, no greater than 500 ft in length, 300 volt wire.
• When connecting to the terminal block, fasten only one wire to each connector screw.
• Torque terminal block screws to 4.4 in-lb [0.49 Newton meter].
• Torque circuit breaker connections to 45 in-lb [5 Newton meter].
Generator ACSystem Connection
A single-phase, three-wire AC connection system is used
in the generator. The stator assembly consists of a pair
of stationary windings with two leads brought out of each
winding. The junction of leads 22 and 33 forms the neutral
lead, as shown schematically and as a wiring diagram.

NOTICE Neutral is not bonded to ground at generator.
NOTICE Generator must be used with only an UL
approved transfer switch that is compatible with the
generator.
