STEP 8. Connecting power supply wiring

If using shielded or armored cable:

a.Ground the shield drain wires (the black wire) only on the core processor end, by connecting it to the ground screw inside the lower conduit ring. Do not ground to the core processor’s mounting screw. Do not ground the cable at the sensor junction box.

b.Ground the cable braid on both ends, by terminating it inside the cable glands.

4.Ensure integrity of gaskets, grease all O-rings, then close the junction box housing and core processor end-cap, and tighten all screws.

CAUTION

Damaging the wires that connect the transmitter to the sensor can cause measurement error or meter failure.

To reduce the risk of measurement error or meter failure, when closing the housings on the sensor and core processor, make sure that the wires are not caught or pinched.

STEP 8. Connecting power supply wiring

CAUTION

Improper wiring installation can cause device failure or measurement error.

To avoid device failure or measurement error, do not install power supply wiring in the same cable tray or conduit as input/output wiring.

Shut off power supply before installing the applications platform.

Make sure power supply voltage matches voltage that is indicated on power supply wiring terminals. See Figure 12.
