3. Separate the module base from the housing by performing the Removing the Module Base procedure.<br />
4. Disconnect the terminal box wiring connector from the PWB assembly (key 50).<br />
5. Remove the screw (key 72). Pull the terminal box assembly straight out of the housing.<br />
Replacing the Terminal Box<br />
Note<br />
Inspect all O‐rings for wear and replace as necessary.<br />
1. Apply lubricant, silicone sealant to the O‐ring (key 34) and install the O‐ring over the stem of the terminal box.<br />
2. Insert the terminal box assembly stem into the housing until it bottoms out. Position the terminal box assembly so<br />
that the hole for the screw (key 72) in the terminal box aligns with the threaded hole in the housing. Install the<br />
screw (key 72).<br />
3. Connect the terminal box wiring connector to the PWB assembly (key 50). Orientation of the connector is required.<br />
4. Reassemble the module base to the housing by performing the Replacing the Module Base procedure.<br />
5. Reconnect the field wiring as noted in step 2 in the Removing the Terminal Box procedure.<br />
6. Apply lubricant, silicone sealant to the O‐ring (key 36) and install the O‐ring over the 2‐5/8 inch threads of the<br />
terminal box. Use of a tool is recommended to prevent cutting the O‐ring while installing it over the threads.<br />
7. Apply lithium grease (key 63) to the 2‐5/8 inch threads on the terminal box to prevent seizing or galling when the<br />
cap is installed.<br />
8. Screw the cap (key 4) onto the terminal box.<br />
9. Install a set screw (key 58) into the cap (key 4). Loosen the cap (not more than 1 turn) to align the set screw over<br />
one of the recesses in the terminal box. Tighten the set screw (key 58).<br />
