Wire Sizes and Lengths for the DALI Bus of the RP Controller Expansion DALI Light Modules
This section provides recommendations on wire sizes and lengths for the DALI bus of the RP controller expansion DALI light modules.
The DALI bus is connected to the DALI inputs/outputs, labeled Light 1 to Light 4, of the DALI light modules. The DALI inputs/outputs have two terminals, labeled DA+ and DA-, to which the two-wire bus is connected.
The recommendations are for guidance only. Other wire sizes and lengths may be used, depending on wiring rules and when appropriate.
Only copper wires should be used for the DALI bus.
