3. Ground the cable.

4. Ensure the integrity of the gaskets, grease all O-rings, then close the junction box

housing and core processor end-cap, and tighten all screws.

3.4

Connect the power supply wiring

Cable type

Procedure

Jacketed cable

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.

Shielded or armored cable

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.

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

cable glands.

CAUTION!

Make sure that the wires are not caught or pinched when you close the housing to reduce the risk of
measurement error or meter failure.

CAUTION!

• Do not install power supply wiring in the same cable tray or conduit as the input/output

wiring to avoid device failure or measurement error.

• Shut off the power supply before installing the applications platform.
• Make sure the power supply voltage matches the voltage that is indicated on the power

supply wiring terminals. See
