Output Contactor Control
In the unlikely event of failure in the bypass control electronics, the user can engage
the drive output contactor without the control electronics by moving jumper J2 to the
Output Contactor position – see "Adjustment Locations" on page 19. When the
jumper is in the Output Contactor position, the Drive contactor is energized and the
Bypass contactor is de-energized. The contactors, and therefore the system, are not
controlled by the bypass electronics when jumper J2 is in the Output Contactor
