(1) (2) (3)
(1) Control and signal wires must be separated from power wires by at least 0.3 meters (1 foot).
(2) 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.
(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.
