Wiring instructions for remote core processor with
remote transmitter installations
There are two phases to this procedure:
•
Wiring the remote core processor to the transmitter
•
Wiring the sensor to the remote core processor
To wire the remote core processor to the transmitter:
1. Use one of the following methods to shield the wiring:
2. Do one of the following:
•
If you are using shielded cable, prepare the cable and apply shielded heat shrink
as described in Step 6. The shielded heat shrink provides a shield termination
Installation method
Procedure
Unshielded wiring in continuous metallic conduit that provides 360°
termination shielding for the enclosed wiring
Go to Step 8
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
Go to Step 8
A Micro Motion-supplied cable gland at the core processor housing
Go to Step 2
Core processor terminals
