1756-MxxSE SERCOS Interface Module Noise Zones
Observe the following guidelines when installing your 1756-MxxSE SERCOS
interface module.
• The clean zone (C) is beneath the less noisy I/O modules (analog,
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.
