SM Meter Assembly
The SM 3000 Meter assembly includes an integral filter plate and an associated mounting plate in the
flameproof/explosion-proof housing as shown in Figure 5. To install an SM 3000 Smart Meter:
•
Remove the cap from the housing.
•
Rotate the meter assembly counter-clockwise until it can be pulled from the mounting plate in the
housing.
•
Connect field wiring to the terminal block in the housing.
•
Align four stand-offs on the bottom of the meter assembly with holes in the mounting plate, insert
bottom of stand-offs in the holes, and turn the meter assembly clockwise to lock it in place. Ensure
that the meter is oriented properly for viewing through the cap window.
•
Lubricate the threads and the o-ring on the meter housing with silicon grease such as Dow Corning
#33.
•
Replace the cap.
