1-14 Installing Your Ultra1500
Establishing Noise Zones
Observe the following guidelines when laying out your panel (refer to Figure
1.5 for zone locations).
• The clean zone (C) is above and beneath the Ultra1500 and includes CN1,
CN2, and CN3 signals, and the DC filter (grey wireways).
• The dirty zone (D) is left of the Ultra1500 (black wireways) and includes
the circuit breakers, transformer, AC line filter, contactors, 24V dc power
supply, and motor (output) power cables.
• The very dirty zone (VD) is limited to where the AC line (EMC) filter AC
output jumpers over to the Ultra1500. Shielded cable is required only if
the very dirty cables enter a wireway.

Establishing Noise Zones
1 If I/O cable contains (dirty) relay wires, route cable with motor (output) power wires in dirty wireway.
2 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.
