down until it snaps into place. The cutouts in the
cover edges will engage two alignment tabs on
the rear panel.
Where needed, the Ethernet cable should exit
through the large cutout in the cover.
To Remove Cover:

FIGURE 8-1 Direct Entry Connectors, Cover Installation and Removal
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 the above figure.
COVER AND CONNECTOR REMOVAL AND INSTALLATION, SIDE ENTRY
Removal:
1. Remove the connector cover by slightly compressing the cover’s U-shaped extrusion to free the cover’s tabs.
The cover may be secured by two screws, as described below. The cover is shown in Figure 8-5.
2. 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. Grasp the connector tab and pull straight out from the case. A slight bias on the pull toward the center of the
Connector Socket will often ease removal. See Figure 8-3. Be careful not to stress or damage connected wires
and components.
