The sensor cable must be shielded. The shield:
•
must extend the length of the cable, but be connected only
at the 1771 I/O chassis
•
must extend up to the point of termination
Important: The shield should extend to the termination point,
exposing just enough cable to adequately terminate the
inner conductors. Use heat shrink or another suitable
insulation where the wire exits the cable jacket.
