The use of shielded cable is recommended for the PTC thermistor circuit to assist in
obtaining compliance with Electromagnetic Compatibility (EMC) requirements.
Shielded cable is recommended for the input circuits, where wire lengths exceed 200
meters (656 feet).
NOTE: For reliable input signal processing, input wiring should be routed in raceways
separate from power cabling.
