Compac 6 Control Unit Installation If Compac 6 control units have been removed from the structure, reinstall
them when maintenance work on them is complete. For control unit
replacement, follow these instructions:
1. Turn off all power supplying this equipment before working on or inside
the equipment, and follow lockout/tagout procedures. Always use a
properly rated voltage sensing device to confirm the power is off.
2. Ensure that the operator handle of the control unit is in the OFF position.
3. Place the control unit into the structure in the proper location.
4. Position the mounting slides of the control unit onto the slots of the
mid-shelf. Slide the unit inward until the unit is halfway in, then move it
inward with a quick push. This movement easily overcomes the
compression of the stabs as they engage the vertical bus (Figure 127).
NOTE: The interlock is spring loaded and engages automatically when
the control unit is inserted with a firm push to the operator handle.
Pressing the structure interlock release is not necessary.
5. Retrieve the pull-apart terminal block from the vertical wire trough in
through the wiring port.
6. Connect the pull-apart terminal block to the
control
unit. If necessary,
remove the control panel. Replace the control panel when the connection
is made.
7. Refer to the termination tags placed during removal of the control unit
(Step 4 on 61) to properly connect the power wiring to the starter
terminals.
8. Shut the door and tighten the fasteners (see Detail B of Figure 115 on
page 95).
