The following table provides information and guidelines about the functions, ratings, and requirements for the input and output terminals; and references guidelines for determining proper wire sizes and cable lengths.
In addition to the wiring guidelines in the following table, observe these guidelines when wiring inputs and outputs:
-
Run all low-voltage wiring and cables separate from high-voltage wiring.
-
All input and output cables, regardless of wire size or number of wires, must consist of stranded, insulated, and twisted copper wires.
-
Shielded cable is not required for input or output cables.
-
Shielded cable is required for input and output cables that are exposed to high electromagnetic or radio frequency noise.
-
Inputs or outputs with cables less than 30 m (100 ft) do not require an offset in the software setup. Cable runs over 30 m (100 ft) may require an offset in the input/output software setup.
