Chapter 2 Install the Kinetix 3 Drive System
Establishing Noise Zones
When the several components such as AC line filter, contactors, circuit breaker,
and transformer are used in the Kinetix 3 system, observe these guidelines when
laying out your panel:
•
The clean zone (C) is beneath the Kinetix 3 drives and includes the I/O
wiring, feedback cable, serial communication cable, and DC filter (grey
wire way).
•
The dirty zone (D) is above the Kinetix 3 drives (black wire way) and
includes the circuit breakers, transformer, 24V DC power supply,
contactors, AC line filter, and motor power cables.
•
The very dirty zone (VD) is limited to where the AC line (EMC) filter
VAC output connects to the Kinetix 3 drives. Shielded cable is required
only if the very dirty cables enter a wire way.

(1) If drive system I/O cable contains dirty relay wires, route cable in dirty wireway.
(2) For tight spaces use a grounded steel shield. For examples, refer to the System Design for Control of Electrical Noise Reference
Manual, publication GMC-RM001 .
(3) This is a clean 24V DC available for any device that requires it. The 24V enters the clean wireway and exits to the left.
(4) This is a dirty 24V DC available for motor brakes and contactors. The 24V enters the dirty wireway and exits to the right.
