(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.
