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, and BACnet/IP device onboard I/O, 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. Always use the recommended cables and wires.
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, and BACnet/IP devices. 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.
You connect RP controller expansion modules and multi-sensors to the RP-C room bus to provide the devices with power and communication from the RP-C controller.
The wiring recommendations for the communication ports on the automation servers, BACnet/IP devices, 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 controller Modbus network connections. Always use the recommended cables and wires.
The wiring recommendations provide guidance regarding wiring of the Central IO modules, automation servers, BACnet/IP devices, RP controller expansion modules, and Operator Display.

It is important to perform the grounding correctly for the following reasons:
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.
