Grounding and Power for Systems with RP-C 230 V Controller Models and RP Controller Expansion Modules

This section provides grounding and power recommendations for system configurations with the RP-C controller models that support 230 VAC input power and RP controller expansion modules.

HAZARD OF ELECTRIC SHOCK, EXPLOSION, OR ARC FLASH

De-energize the high-voltage relay contacts before wiring. More than one disconnect switch may be required to de-energize the equipment before servicing.

Failure to follow these instructions will result in death or serious injury.

System configuration with separate power supplies to RP-C 230 V controller model and RP controller expansion modules with power distribution capability

You can use separate power supplies, with separate fuses (circuit breakers), to power the RP-C 230 V controller model and the RP controller expansion modules to help prevent a problem (such as a short-circuit) with one expansion module from causing the RP-C controller to stop working.

Use the following recommendations to design a good working system:

  • The fuse (circuit breaker) F1 must be rated 3 A or higher (maximum 16 A).

  • The fuse (circuit breaker) F2 must be rated at maximum 16 A.

Aviso

To achieve load balancing, the Power Input terminal L (Line) for different RP controller expansion modules can be connected to different phases of the AC mains power supply.

System configuration with a common power supply to RP-C 230 V controller model and RP controller expansion modules with power distribution capability

You can use a common power supply, with a common fuse (circuit breaker), to power the RP-C 230 V controller model and several RP controller expansion modules to reduce the costs of wiring and fuses. However, if there is a problem such as a short-circuit in one of the expansion modules, and the common fuse is blown, the RP-C controller and all expansion modules connected to the same fuse will also stop working. Furthermore, if several RP-C controllers are connected using a daisy chain topology, a problem in one expansion module can in this way cause all controllers downstream from RP-C controller that has stopped working to lose communication to all upstream controllers.

Use the following recommendations to design a good working system:

  • The fuse (circuit breaker) F1 must be rated 3 A or higher (maximum 16 A).
