Install the Kinetix 350 Drive System Chapter 2
Establish Noise Zones
Observe these guidelines when individual input power components are used in
the Kinetix 350 system:
• The clean zone (C) exits left of the Kinetix 350 system and includes the
I/O wiring, feedback cable, Ethernet cable, and DC filter (gray
wireway).
• The dirty zone (D) exits right of the Kinetix 350 system (black wireway)
and includes the circuit breakers, transformer, 24V DC power supply,
contactors, AC line filter, motor power, and safety cables.
• The very dirty zone (VD) is limited to where the AC line (EMC) filter
VAC output jumpers over to the drive. Shielded cable is required only if
the very dirty cables enter a wireway.
Figure 6 - Noise Zones (Bulletin 2090 AC line filters)
(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 voltage 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 voltage is a dirty 24V DC available for motor brakes and contactors. The 24V enters the dirty wireway and exits to the right.
