3. Disconnect the trip coil leads from the auxiliary assembly. Take note of

the lead termination points.

4. Pull the latch assembly forward and out of the contactor as shown in

Figure 4.20. The loose mounting bolts can be re-installed later. The trip
coil leads are secured with wire ties at the back of the contactor, clip the
ties to allow removal of the leads.

Note: On older contactors, the trip coil leads are routed under the closing
coil. If it is difficult to remove the leads, loosen the closing core mounting
bolt to allow the coil to be tilted up slightly and pull the leads out, then
tighten the core mounting bolt immediately. Do not loosen both core
mounting bolts at the same time
