CAUTION
To prevent damage to the interconnecting pins when installing the Electronics Module, use the guide pins to insert the
Electronics Module straight onto the Transducer housing receptacles without twisting or turning.
2. Tighten the two mounting screws. Replace the LCD meter assembly.
3. Replace the cover. Tighten 1/3 of a revolution after the cover begins to compress the O‐ring. Both instrument
covers must be fully engaged to meet explosion‐proof requirements.
Terminal Box
The terminal box is located on the transducer housing and contains the terminal strip assembly for field wiring
connections. Unless indicated otherwise, refer to figure 7‐3.
WARNING
On an explosion‐proof instrument, remove the electrical power before removing the instrument covers in a hazardous
area. Personal injury or property damage may result from fire and explosion if power is applied to the instrument with the
covers removed.
Removing the Terminal Box
1. Loosen the set screw (key 31) in the terminal box cover assembly (key 6) so that the cover can be unscrewed from
the terminal box.
2. After removing the cover (key 6), note the location of field wiring connections and disconnect the field wiring from
the wiring terminals.
3. Remove the screw (key 7), and pull out the terminal box assembly.
CAUTION
To avoid damaging the terminal box assembly connector, pull the terminal box assembly straight out of the housing,
without twisting or turning.
Replacing the Terminal Box
Note
Inspect all O‐rings for wear and replace as necessary.
