3. Position the new assembly on the left side plate of the contactor with the
cam followers (see Figure 4.28) protruding through the rectangular holes in
the operating lever. Install and allow the mounting bolts to remain loose so
that the assembly can slide vertically on its mounting slots.
4. With the contactor “off ”, push the entire auxiliary assembly up until the cam
followers bottom out against the top of the rectangular holes in the operat-
ing lever as shown in Figure 4.28 (make sure the armature plate is against
the stop such that the contactor is fully open). At this point, the top set of
auxiliary contacts are “closed” and the bottom set of auxiliary contacts are
“open”.
5. Tighten and torque (6 ft-lb) the mounting bolts to fix the position of the
auxiliary assembly.
