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.
It is important to perform the grounding correctly for the following reasons:
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.
The Schneider Electric EasyLogic and SpaceLogic hardware devices for the EcoStruxure BMS include terminal bases, PS-24V power supplies, Central IO modules, automation servers such as AS-P and AS-B servers, MP-C, MP-V, RP-C, and RP-V controllers, IP-IO and RP-IO I/O modules, RP controller expansion modules, remote control, KNX Modbus gateway, Bluetooth adapter, Wireless Adapter - Advanced, SpaceLogic Sensor devices, Advanced Display devices, and Operator Display devices.
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.
