Coil Replacement Instructions
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 benchtop position as shown.
3. Remove the cover attachment screws from the contactor and remove the cover (Figure 3A).
4. Disconnect the coil wire leads from the Control-Pak. Remove the Control-Pak from the contactor and set on benchtop (Figure 3B).
5. While supporting the Main Housing, remove the Main Housing from the Baseplate by removing the (4) screws which hold the housing
to the Baseplate. A long phillips-head screwdriver (6" or longer) is needed as the four screws are in deep wells (holes) in the Main
Housing. Remove the shorter screws first. Separate the main housing assembly from the Baseplate and set it aside.
(Figure 3C).
Installation Instructions
The vacuum contactor may be used in any mounting plane. In any non-horizontal mounting plane, the top of the contactor should point up
(so that the label appears right-side up). Care should be taken to insure that the mounting hardware does not warp the mechanism frame.
If the surface of the contactor to which the contactor is mounted is twisted, shims should be used to correct the condition. Any appreciable
degree of end to end twist will result in phase to phase discrepancies and timing of the main contact could cause increased pickup in
control voltage values.
1. Figure 1 illustrates the field terminals for line and load terminations. Mount the contactor with the hardware specified in Figure 2.
Loosely install the (4) mounting bolts into the intended mounting surface. Torque the mounting bolts to 50 - 75 lb-inches.
2. Connect control wires to the vacuum contactor control terminals A1 and A2 located on the Control-Pak using #18 to #12 gauge 75°C
stranded copper or tin stranded copper wire tightening screw terminals to 7 lb-inches torque.
3. Using 75°C wire copper cable, connect the line and load conductors to the main terminals (Figure 1) and proper phase rotation, tighten
the main terminal bolts to 132 lb-inches torque.
4. Check all connections for accuracy and mechanical connection before energizing.
