Agency Compliance

This topic describes the requirements for compliance with various agencies.

Designations
CE	RMC200: all modules RMC75: RMC75E CPU only - contact Delta for other modules
UL, CUL	RC75: all modules RMC150: all modules RMC200: all modules
Class I, Division 2	RMC150E, RMC151E (when ordered with -HZ option). All modules except Analog (G), Stepper (QST), or Universal I/O (UI/O or U) modules. File E329627.

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.
RMC200 only:

Install a ferrite on the power wires to the PS4D or PS6D power supply. Recommended ferrite is Fair-Rite 0431167281. The integrated power supply on the CPU20L does not require this ferrite.
Keep module closed during operation (for ESD susceptibility requirements)

UL and CUL

File number: E141684

RMC75, RMC150

The RMC75 and RMC150E are UL and CUL compliant. For UL and CUL compliance:

Power supply must be Class 2.
All RMC inputs and outputs must be connected to Class 2 circuits only.

RMC200

All RMC200 modules are UL and CUL compliant.

Class I Division 2

File Number: E329627

Hazardous location designation Class I, Division 2, Groups A, B, C, D is available for the RMC150E. See the RMC150 Part Numbering topic for how to specify Class I, Division 2 when ordering.

Products marked ”Class I Division 2, Group A, B, C, D” are suitable for use in Class I Division 2, Groups A, B, C, and D hazardous locations and nonhazardous locations only.
WARNING—EXPLOSION HAZARD—DO NOT DISCONNECT EQUIPMENT WHILE THE CIRCUIT IS LIVE OR UNLESS THE AREA IS KNOWN TO BE FREE OF IGNITABLE CONCENTRATIONS.
WARNING—EXPLOSION HAZARD—SUBSTITUTION OF ANY COMPONENT MAY IMPAIR SUITABILITY FOR CLASS I, DIVISION 2.
Maximum surrounding air temperature of 60° C.
The RMC150E USB port is intended for configuration, programming, and troubleshooting purposes only. It should not be connected during normal operation.
See the Wiring Guidelines for wire gauge, screw clamp torque and wire type requirements.
