Use shielded, properly grounded cables for all analog and high-speed inputs or outputs and communication connections. If you do not use shielded cable for these connections, electromagnetic interference can cause signal degradation. Degraded signals can cause the controller or attached modules and equipment to perform in an unintended manner.

WARNING
	UNINTENDED EQUIPMENT OPERATION Use shielded cables for all fast I/O, analog I/O, and communication signals. Ground cable shields for all fast I/O, analog I/O, and communication signals at a single point¹. Route communications and I/O cables separately from power cables. Failure to follow these instructions can result in death, serious injury, or equipment damage.

¹Multipoint grounding is permissible (and in some cases inevitable) if connections are made to an equipotential ground plane dimensioned to help avoid cable shield damage in the event of power system short-circuit currents.

WARNING
	UNINTENDED EQUIPMENT OPERATION Do not connect wires to unused terminals and/or terminals indicated as “No Connection (N.C.)”. Failure to follow these instructions can result in death, serious injury, or equipment damage.
