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 C-UL compliance:
Power supply must be Class 2.
All RMC inputs and outputs must be connected to Class 2 circuits only.
