Installation/Wiring 1-23
I/O Wiring Important points to remember about I/O wiring:
• Use Copper wire only. Wire gauge requirements and recommendations
are based on 75°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).
• 4100CCF3 Flex I/O cable for use with DriveLogix™ is 0.9 meters (3 ft.)
maximum length.
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.
Signal and Control Wire Types
Table 1.F Recommended Signal Wire
!
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.

(1) Belden 9730 is 3 individually shielded pairs (2 channel plus power). If 3 channel is required, use Belden 9728 (or equivalent).
(2) Belden 8790 is 1 shielded pair.
(3)
Belden 9892 is 3 individually shielded pairs (3 channel), 0.33 mm
2
(22 AWG) plus 1 shielded pair 0.5 mm
2
(20 AWG) for power.
(4) Belden 9773 is 3 individually shielded pairs (2 channel plus power). If 3 channel is required, use Belden 9774 (or equivalent).
(5) 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.
