To avoid personal injury or property damage caused by fire or explosion, remove power to the instrument before removing

the terminal box cover in an area which contains a potentially explosive atmosphere or has been classified as hazardous.

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 PWB assembly (key 50).

5. Remove the screw (key 72). Pull the terminal box assembly straight out of the housing.

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 PWB assembly (key 50). Orientation of the connector is required.
