Wiring
The following points must be considered:
Figure: Typical texture of used wires
Figure: Different polarity of DALI lines
DALI systems are installed using conventional wiring material for line voltage.
Two wires are needed for the DALI control circuit.
The line voltage and bus line may be routed in the same cable. This corresponds to a 5-core cable (L, N, PE,
DA, DA)
I NOTICE
According to DIN VDE 0100/T520/Part 6, main circuits and associated auxiliary circuits may be laid together even if
the auxiliary circuits carry a lower voltage than the main circuits. Make sure to use cable designed to take the
maximum operating voltage.
There is no need to worry about the polarity of the DALI line.
The DALI signal is not SELV. The installation instructions for low voltage therefore apply
There are no special network topology requirements (star and mixed networking are permitted)
