Wire Sizes and Lengths for the DALI Bus of the RP Series Expansion DALI Light Modules

This section provides recommendations on wire sizes and lengths for the DALI bus of the RP Series expansion DALI light modules.

The DALI bus is connected to the Light outputs of the DALI light modules. The Light 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.
