Wiring
Core processor to a 4-wire remote transmitter
Follow the steps below to connect the 4-wire cable between the core processor and the transmitter.
1. Use one of the following methods to shield the wiring from the core processor to the transmitter:
• If you are installing unshielded wiring in continuous metallic conduit that provides 360°
termination shielding for the enclosed wiring, go to page 20 (step 6 of the wiring procedure).
• If you are installing a user-supplied cable gland with shielded cable or armored cable, terminate
the shields in the cable gland. Terminate both the armored braid and the shield drain wires in the
cable gland. Never connect the drain wires to the internal ground screw of the core processor. Go
to page 20 (step 6 of the wiring procedure).
• If you are installing a Micro Motion-supplied cable gland at the core processor housing:
- Prepare the cable and apply shielded heat shrink as described below. The shielded heat shrink
provides a shield termination suitable for use in the gland when using cable whose shield
consists of foil and not a braid. Proceed to step 2 of the wiring procedure, below.
- With armored cable, where the shield consists of braid, prepare the cable as described below,
but do not apply heat shrink. Proceed to step 2 of the wiring procedure, below.
2. Remove the cover from the core processor housing.
3. Slide the gland nut and the clamping insert over the cable.

4. For connection at the core processor housing, prepare shielded cable as follows (for armored cable,
omit steps d, e, f, and g):
a. Strip 4 1/2 inches (114 mm) of cable jacket.
b. Remove the clear wrap that is inside the cable jacket, and remove the filler material between the
wires.
c. Remove the foil shield that is around the insulated wires, leaving 3/4 inch (19 mm) of foil or braid
and drain wires exposed, and separate the wires.
d. Wrap the shield drain wire(s) around the exposed foil twice. Cut off the excess wire.
