(1) Signal wires should be separated from power wires by at least 0.3 meters (1 foot).
(2) If the wires are short and contained within a enclosure which has no sensitive circuits, the use of shielded wire may not be necessary, but is always recommended.
(3) I/O terminals labeled ‘(–)’ or ‘Common’ are not referenced to earth ground and are designed to greatly reduce common mode interference. Grounding these terminals can cause signal noise.
(4) Safety option modules 20-750-S, 20-750-S1, and 20-750-S3 require shielded cable.
