AC Power Noise Zones
Observe the following guidelines when laying out a Kinetix 7000 system panel, if
an AC power supply is used (and regenerative power will not be used).
• The clean zone (C) is beneath and left of the Kinetix 7000 drive. This zone
includes the motor feedback, auxiliary feedback and registration signals
from the IOD connector (grey wireway).
• One dirty zone (D) is beneath and right of the Kinetix 7000 drive. This
zone includes fuses, contactors, circuit breakers, AC line input to the
EMC line filter (black wireway).
• The very dirty zone (VD) is limited to where the AC line output exits
from the EMC line filter and connects to the Kinetix 7000 drive. Shielded
cable is required only if the very dirty cables enter a wireway.
• The SERCOS fiber-optic cables are immune to electrical noise.

(1) When space does not permit the 150 mm (6.0 in.) segregation, use a grounded steel shield instead. For examples, see the System
Design for Control of electrical Noise Reference Manual, publication
