2.4.1 Removing the Covers
WARNING!
Always disconnect the line power from the meters before removing either the front cover or the side
cover. This is especially important in a hazardous environment.
1. Disconnect any previously wired power line from the flow transmitter.
2. Loosen the set screw on the side cover using a 2.5 mm hex wrench.
3. Place a rod or long screwdriver across the cover in the slots provided, and rotate the cover counterclockwise until
it comes free from the enclosure.
4. Note the text imprinted on the terminal board (see Figure 10 below) to assist in wiring the power and option card
connections.
Proceed to the appropriate section of this chapter to make the desired wiring connections.

2.4.2 Cable Tie-Down Posts
There are two cable tie-down posts provided in the
Sentinel LNG
(see Figure 11 below). These posts enable the user to
insert a cable tie through them, and secure wiring coming into or out of the instrument. The posts rotate on the
printed circuit board to provide ease-of-use.
