Wire Sizes and Lengths for the RP-C 230 V Controller Models
This section provides recommendations on wires sizes and lengths for the RP-C 230 V controller models.
For more information, see RP-C Models .
The recommendations are for guidance only. Other wire sizes and lengths may be used, depending on wiring rules and when appropriate.
Screw terminal number 3 differs between different hardware versions of the controller model RP-C-16A-F-230V. For more information, see Differences Between RP-C Hardware Versions .
