Installation/Wiring 1-25
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: 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.
