Installation/Wiring
Important points to remember about I/O wiring:
•
Use copper wire only. Wire gauge requirements and
recommendations are based on 75 degree C. Do not reduce wire
gauge when using higher temperature 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).
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.

I/O Wiring
!
ATTENTION:
Configuring an analog input for 0-20mA operation and
driving it from a voltage source could cause component damage. Verify
proper configuration prior to applying input signals.
!
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.
