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.

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 and Retainer (Figure 3A).
4. Disconnect the two wire leads from the Coil to the Control-Pak. Remove the Control-Pak from the contactor and set on benchtop (Figure 3B).
5.
Remove the (6) screws that secure the Upper Housing to the Lower Housing by first removing the (4) outer screws and then (2) center
screws. NOTE- Removing the center screws will release the Return Springs. Carefully remove the Upper Housing leaving the Return Springs
in the Lower Housing

(Figure 3B)).
