10.1. Wiring Guidelines
Proper wiring of the RMC and of the system is important for proper machine control. Poor
wiring is a common source of noisy feedback, drive signals or digital I/O. Follow the guidelines
in this topic and the other wiring topics to ensure a low-noise system.
General Wiring Instructions
For CE compliance and to minimize electrical interference:
•
Use twisted pairs for all wiring where possible.
•
Use shielded cables for all wiring.
•
Keep RMC wiring separate from AC mains or conductors carrying high currents,
especially high frequency switching power such as conductors between servo drives
and motors or amplifiers and proportional valves.
For UL and CUL compliance:
•
Power supply must be Class 2.
•
All RMC inputs and outputs must be connected to Class 2 circuits only.
Fusing
No fusing is required if a Class 2 power supply is used, as required by UL. Class 2 power
supplies are limited to 100W output. This provides sufficient protection for the RMC and
no additional fusing is required.
For Class I, Division 2 compliance (only available for RMC150E with the Class I,
Division 2 designation)
•
The RMC150E USB port is intended for configuration, programming, and
troubleshooting purposes only. Do not leave it connected during normal machine
operation, as it is sensitive to electrical noise.
•
Conductors must be copper only.
