Notes
• Ground the shield drain wires (the black wire) only on the remote core processor end,
by connecting it to the ground screw inside the lower conduit ring. Never ground to
the core processor’s mounting screw. Never ground the cable at the sensor junction
box.
• Ground the cable braid on both ends, by terminating it inside the cable glands.
b. Tighten the screws to hold the wires in place.
c. Ensure integrity of gaskets, grease all O-rings, then replace the junction box
cover and remote core processor end-cap and tighten all screws, as required.
