This section provides recommendations on minimum wire sizes (cross-sectional areas) and maximum wire lengths for the wires connected to the screw terminals of Central IO modules, AS-B servers, RP and MP controllers, and IP-IO and RP-IO I/O modules. Recommendations on minimum wire size and maximum cable length for the digital inputs of the RP controller expansion modules, the DALI bus of the DALI light modules, the SMI Interface of the SMI blind modules, the Zigbee DALI and 0-10V modules, and the KNX Modbus gateway are also provided. The recommendations are for guidance only. Other wire sizes and lengths may be used, depending on wiring rules and when appropriate.

The RP controller expansion module can be installed on a DIN rail or other flat surface inside a cabinet. The device is recommended to be installed in a cabinet, unless local regulations allow an exception.
The RP-C-EXT-REL-4 relay module connects to the RP-C room controllers and enables power supply and control of lights.
The RP controller room bus allows RP controller expansion modules to be connected to the controller for people counting, motion detection, luminosity and sound pressure level measurements, Bluetooth Low Energy based applications, and control of electric lights and window blinds.
The wiring recommendations for the communication ports on the automation servers, RP and MP controllers, IP-IO and RP-IO modules, RP controller expansion modules, and Operator Display devices apply to wires and cables used for RS-485 communications, LonWorks communications, USB connections, Ethernet connections, sensor bus connections, room bus connections, and RP and MP controller Modbus network connections. Always use the recommended cables and wires.
You connect RP controller expansion modules to the RP controller room bus to provide the devices with power and communication from the controller.
The I/O wiring recommendations provide guidance on what type of wires should be used for the different Central IO modules, AS-B server onboard I/O, RP and MP controller onboard I/O, and IP-IO and RP-IO I/O modules, how to perform grounding, and how to connect different external devices to the inputs and outputs. This section also provides information on the external connectors required for the RP controller expansion modules and the RP-C-16C-F-230V model. Always use the recommended cables and wires.
It is important to perform the grounding correctly for the following reasons:
