1. Disconnect all power cables (or bus work) and all control wiring to the contactor.

2. Remove the contactor from its mounted location. The contactor is best serviced in the tabletop position.

3. Remove the cover attachment hardware from the contactor and remove the cover (Figure 1).

4. Disconnect the coil wire leads from the Control-Pak or Auxiliary (Figure 2B).

5. Remove the Control-Pak from the contactor by first rotating the retainer to release the top tab of the Control-Pak. Then pull out the top of the Control-Pak (the tab must clear the notch) and then push Control-Pak slightly downward to release lower tab that holds the Control-Pak to the housing (Figures 2A & 2B).

This tab must clear notch priorto pushingControl-Pak downward.

Vacuum Interrupter Phase Assembly Replacement (Cont'd)6. Locate the replacement Interrupter Phase Assembly that needs to be replaced. It is recommended that all three interrupters be replaced at the same time.

7. For the outer interrupters, remove the Retainer. While holding the Interrupter in position with the provided wrench, remove the screw from the line side terminal (Figure 3).

8. Remove the shunt screw from the load side terminal (See Section A-A). This will free the shunt. Carefully remove the interrupter assembly (Figure 4).

9. The replacement interrupter is factory set for contact gap and does not require adjustment. The flexible shunt will feed through the flexible shunt path in the molding of the contactor and the assembly can be pushed firmly back into place (See Figure 4 showing locations for applying hand pressure to snap interrupter into plastic molding), observe the adjacent phases to see precisely how this is positioned. While holding the Interrupter in position with the provided wrench, replace the line terminal screw (Figure 3). Replace the shunt connection hardware (Figure 4). Torque screw to 60 - 80 lb-inches.

10. Reinstall the Control-Pak (Figures 5A & 5B). First, insert the lower tab into the recess on the side of the contactor base. With proper installation, the Actuator will fit into the hole in the slot in the side of the contactor housing. Using a thin rod or flat blade, lift the Actuator up as necessary to insert it into the slot mentioned.

11. Reinstall the cover and secure it with the original mounting hardware. NOTE: Cover must fit under metal bracket on Control-Pak. Tighten the four screws in a diagonal pattern to 12 lb-inches. (Figure 1).

12. Reattach the coil wire leads and any auxiliary control wires to the Control-Pak (tighten to 7 lb-inches).

13. Reinstall the contactor. Torque mounting screws to 50 - 75 lb-inches.

14. Reconnect the line and load conductors and tighten the main terminal hardware and bolts to 180 - 210 lb-inches.
