9 ATTENTION: Plug-in MCC units can be heavy or awkward to handle. Use an assistant or a platform lift device if necessary to help you handle the unit. 1. Remove the protective caps from the stab openings or open the manual shutters if present (automatic shutters open as the units are inserted). 2. For 0.5 space factor units, place the unit on the bottom unit support pan, slide the unit interlock to the left and push the unit into the section until it is in the desired position, then release the unit interlock. Unit devices have been omitted for clarity. Left Unit Guide Bushing Slot Unit Support Pan Right Unit Guide Normal Operating Position Disconnected Position IMPORTANT Note that there are two positions available (normal operating and disconnected). In the normal operating position, the power and ground stabs are connected to their respective busses. In the disconnected position, the unit is partially removed from the MCC and the intermediate slot in the interlock plate is in line with the bushing located in the unit support pan. When the unit is locked in this position, the unit power and ground stabs are disengaged. This position can be used to prevent insertion of a unit into the MCC. ATTENTION: For proper operation of the latch/interlock mechanism, a style 3 unit-support pan with bushing must be used below the unit. If the unit support pan with bushing is not used, the unit could be removed under load, resulting in injury or death. 3. For 1.0 space factor and larger units, place the unit on the unit support pan and slide it into the section until it is flush with the front of the structure and the power stabs are connected to the vertical bus. TIP Reposition your hands as necessary to properly support the unit while you are installing the unit into the MCC. TIP For Feeder units, you need to tilt the top of the unit slightly to the rear to avoid interference with the top angle latch bracket. If you do not have enough clearance, you need to loosen the angle latch bracket screw (approximately two turns) to install the unit. Rockwell Automation Publication 2100-IN092A-EN-P - April

10 4. For 1.0 space factor and larger units, secure the unit by tightening the top and bottom captive latches to 22 lb in (2.5 N m). Units that are 2.0 space factors or larger have two captive latches on the top of the unit and one on the bottom of the unit. 1.0 Space Factor and Larger Units Unit support pan above the unit not shown for clarity. IMPORTANT Top captive latch must be rotated to vertical and engage behind the front flange of the unit support pan above the unit. The bottom captive latch must be rotated to vertical and engaged into the slot of the unit support pan as shown. 5. Connect the marked unit load wires. 6. Connect the marked control wires. 7. Verify that all power and control wires have been connected properly and to the proper phases. Install New Door Latch Screw and Label Follow these steps to install the new door latch. 1.
