Connecting Your Ultra5000 3-5
Routing High and Low Voltage Cables
Be aware that when you connect and route power and signal wiring
on a machine or system, radiated noise from nearby relays (relay coils
should have surge suppressors), transformers, and other electronic
drives, can be induced into motor or encoder feedback,
communications, or other sensitive low voltage signals. This can cause
system faults and communication problems. To minimize the levels of
radiated noise, route machine power and signal lines separately.

Always separate all low voltage signal
wiring from high voltage power wiring to
reduce affects of EMI and RFI.
