No mains voltage at the power contacts
The terminal points for the power contacts (+24 V, 0 V) must not be connected to 230 V mains voltage un-
der any circumstances, since this would destroy the KL6811.
Contacts for the DALI control cable (DALI+, DALI-) and mains voltage
If the contacts for the DALI control line (DALI+, DALI-) are accidentally connected to 230 V mains
voltage, the KL6811 is not destroyed, but switches off.
Line lengths in DALI mode
The DALI bus can be configured in a line or star topology, or in a mix of the two. The maximum cable length
must not exceed 300 m!
