9.2.5.1—Shields and Grounding
Do not connect chassis ground or PE ground to signal common.
An individual shield termination is provided at the FTM terminal block for each of
the analog inputs and analog outputs. All of the analog inputs and outputs should
be wired using shielded, twisted-pair wiring. The shields should be connected to
earth ground at one point only as well as terminated at the FTM terminal block;
which will typically AC couple the shield to earth ground. See application note
51204 for a more detailed discussion on shield terminations. The length of
exposed wire extending beyond the shield should be limited to 25 mm (1 inch).
Relay outputs, contact inputs, and power supply wiring do not normally require
shielding, but can be shielded if desired.
