Terminal Purpose
1P Prime power operation
2P Prime power operation
3 Remote start ground—connect transfer
switch or remote start switch to TB2-3 and
TB2-4
3P Prime power operation
4
Remote start—connect transfer switch or
remote start switch to TB2-3 and TB2-4
4P Prime power operation
9 Crank mode selection (open: cyclic crank,
ground: continuous crank); connect TB2-9
to TB2-9A for continuous cranking; leave
TB2-9 open cyclic cranking; see starting
instructions in Section 2, Operation.
9A Crank mode ground
Note:
To use prime power mode—place jumpers across TB2-1P to
TB2-2P, TB2-3P to TB2-4P, and TB2-3 to TB2-4. To deactivate
prime power mode—remove jumpers across TB2-1P to TB2-2P,
TB2-3P to TB2-4P, and TB2-3 to TB2-4.
