34 Planning the Kinetix 2000 Drive System Installation
Observe the following guidelines when installing a 1756-MxxSE SERCOS or
other Logix interface modules:
• The clean zone (C) is beneath the less noisy modules, such as I/O,
encoder, registration (grey wireway).
• The dirty zone (D) is above and below the power supply and noisy
modules (black wireway).
• The SERCOS fiber-optic cables are immune to electrical noise.
Establishing Noise Zones (ControlLogix)
(1) Segregate VD wiring from D and C wiring, or use shielded cable (shield bonded to both panel at both ends)
which then becomes category D.
Cable Categories for Kinetix 2000 Systems
