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 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.
This section provides recommendations on wires sizes and lengths for the power input and power output (power distribution) of the RP controller expansion modules.
The RP controller expansion modules provide a range of devices that can be combined to form a connected room solution. The RP controller expansion modules are connected to the RP controller room bus and provide the RP controllers with I/O expansion and sensors that enable lighting and blind control.
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-BL-SMI-4-HV-PD SMI blind module connects to the RP-C room controllers and provides I/O expansion for control of AC mains-supplied motors (drives) with SMI (Standard Motor Interface for AC applications).
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.
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 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. Always use the recommended cables and wires.
It is important to perform the grounding correctly for the following reasons:
