The following procedure requires the removal of the contactor from the cabinet
(open contactor first).
• Remove the two mounting bolts at the front of the contactor.
• Disconnect the incoming and load line connections at the rear of the
contactor.
• Disconnect the interlock rod from the operating lever on the right side of
the contactor.
• Remove the contactor from the cabinet.

contactor housing as shown in Figure 4.18 (on earlier series contactors
there are four bolts). It is easiest to do this with the contactor lying on its
back.
