1. Identify contaminants and implement methods to reduce their presence.
2. Install protective housing for field mounted controllers.
3. When cleaning equipment and surrounding area, especially the floor, either vacuum away all dust and dirt or
use a dampened rag or mop. Sweeping or dry dusting recirculates dust and dirt.
4. Clean or replace all air conditioning filters, room air filters, and equipment filters regularly.
5. Inform all personnel with access to the equipment of the need for cleanliness.
7.3 MECHANICAL INSTALLATION
The following subsections provide guidelines and procedures for mounting controllers in a panel or rack. The
installation should be structurally rigid and the controllers should be squared in the panel or rack.
7.3.1 Removable Connectors and Covers
To gain access to the case mounted connectors, a cover may need to be removed. Reinstall the cover when wiring is
completed. As discussed above, each connector has a removable portion that can be separated from the case
mounted portion, wired, and then reattached. This section will describe cover removal, connector separation, and
connector installation.
COVER AND CONNECTOR REMOVAL AND INSTALLATION
Removal
1. Squeeze the cover slightly about 2" (5 mm) down from the top and push the cover upward. See Figure 7-1. As
shipped from the factory, the cover is not installed on the case.
2. Locate the connector to be removed. As necessary, disconnect, unclamp, or unbundle wires connected to the
connector to be removed. Be sure there is sufficient slack in the wiring for connector removal.
3. Loosen the two captive screws securing the removable portion of the connector to the fixed portion.
4. Grasp the removable portion and pull it from the fixed portion. Be careful not to stress or damage connected
wires and components.
Installation
1. Align the removable portion of the connector with the fixed portion.
2. Press the removable portion onto the fixed portion.
3. Tighten the two captive screws. Do not over tighten. Check that wires and components remain connected
securely.
4. Install the cover as shown in Figure 7-1.
