I/O Wiring
Important points to remember about I/O wiring:
• Always use copper wire.
• Wire with an insulation rating of 600V or greater is recommended.
• Control and signal wires should be separated from power wires by at least
0.3 meters (1 foot).
• For CE compliance, 115 volt digital input wiring must be shielded or must not exceed 30 meters (98 feet) in length.
• In order to maintain electrical safety for all user-accessible low voltage circuits (ELV/PELV circuits), I/O terminals designated for 24V or lower voltage must not be connected to a circuit of higher voltage or a circuit which is not adequately insulated from dangerous voltages with double or reinforced insulation within other connected equipment or wiring.
• In order to provide electrical safety for user-accessible low voltage I/O circuits which are referenced to earth (PELV circuits) and which may be touched simultaneously, care should be taken to provide a common earth reference for all equipment connected to the drive.
IMPORTANT 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.
ATTENTION: Hazard of personal injury or equipment damage exists when using bipolar input sources. Noise and drift in sensitive input circuits can cause unpredictable changes in motor speed and direction. Use speed command parameters to help reduce input source sensitivity.

(1) Control and 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 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.
(4) Safety option modules 20-750-S and 20-750-S1 require shielded cable.
