1-14 Installing Your Ultra3000
Observe the following guidelines when installing your 1756-MxxSE
SERCOS interface module (refer to Figure 1.8 for zone locations).
• The clean zone (C) is beneath the less noisy modules (I/O, analog,
encoder, registration, etc. (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.
