Installing Your Ultra3000 1-13
Establishing Noise Zones
Observe the following guidelines when laying out your panel (refer to
Figure 1.7 for zone locations).
• The clean zone (C) is above and beneath the Ultra3000 and
includes CN1, CN2, CN3, and the DC filter (grey wireways).
• The dirty zone (D) is left of the Ultra3000 (black wireways) and
includes the circuit breakers, transformer, AC line filter, contactors,
24V dc power supply, and motor power cables.
• The very dirty zone (VD) is limited to where the AC line (EMC)
filter AC output jumpers over to the Ultra3000. Shielded cable is
required only if the very dirty cables enter a wireway.
• The SERCOS fiber-optic cables are immune to electrical noise.

If I/O cable contains (dirty) relay wires, route cable with motor power wires in dirty wireway.

This is a clean 24V dc available for CN1 I/O power supply. The 24V enters the clean wireway and exits to the right.
3
This is a dirty 24V dc available for motor brakes and contactors. The 24V enters the dirty wireway and exits to the
left.
