1. Loosen the set screw (key 58) in the cap (key 4) so that the cap can be unscrewed from the terminal box.
2. After removing the cap (key 4), note the location of field wiring connections and disconnect the field wiring from
the terminal box.
3. Separate the module base from the housing by performing the Removing the Module Base procedure.
4. Disconnect the terminal box wiring connector from the sensor board in the housing assembly (key 50).
5. Remove the screw (key 72). Pull the terminal box assembly straight out of the housing.
Replacing the Terminal Box
Note
Inspect all O‐rings for wear and replace as necessary.
1. Apply lubricant, silicone sealant to the O‐ring (key 34) and install the O‐ring over the stem of the terminal box.
2. Insert the terminal box assembly stem into the housing until it bottoms out. Position the terminal box assembly so
that the hole for the screw (key 72) in the terminal box aligns with the threaded hole in the housing. Install the
screw (key 72).
3. Connect the terminal box wiring connector to the sensor board in the housing assembly (key 50). Orientation of the
connector is required.
4. Reassemble the module base to the housing by performing the Replacing the Module Base procedure.
5. Reconnect the field wiring as noted in step 2 in the Removing the Terminal Box procedure.
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
terminal box. Use of a tool is recommended to prevent cutting the O‐ring while installing it over the threads.
7. Apply lithium grease (key 63) to the 2‐5/8 inch threads on the terminal box to prevent seizing or galling when the
cap is installed.
8. Screw the cap (key 4) onto the terminal box.
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
one of the recesses in the terminal box. Tighten the set screw (key 58).
