Control and signal wires should be separated from power wires by at least 0.3 meters (1 foot).
If the wires are short and contained within a cabinet which has no sensitive circuits, the use of
shielded wire may not be necessary, but is always recommended.
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.
