Rockwell Automation 1102C-COx93_DOx93 Vacuum Contactor (400A / 600A) - Manual (Page 4)

Control-Pak Replacement Instructions
1. Disconnect all control wiring to the Control-Pak.
2. Remove the cover attachment screws from the contactor and remove the cover (Figure 3A) page 2.
3. Remove the Control-Pak from the contactor (Figure 3B) page 2.
4. Install the new Control-Pak (Figure 4A & 4B). First, rotate the Retainer upwards. Next, insert the lower tab into the recess on the side
of the contactor base. With proper installation, the Control-Pak Actuator will fit into the hole in the center of the brass stud - which can be
viewed through the slot in the side of the contactor housing. Using a thin screw driver or other thin rod, push the Control-Pak Actuator up
or down as necessary to insert it into the brass stud mentioned. Rotate the Retainer to its original position, which will slide over the upper
tab on the Control-Pak.
5. Reinstall the cover and secure it with the original mounting hardware. Tighten the four screws in a diagonal pattern to 5 lb-inches
(Figure 3A).
6. Reconnect all control wiring removed per Step 2. Tighten to 7 - 9 lb-inches.
