Risk of injury through electric shock and damage to the device! Bring the Bus Terminals system into a safe, de-energized state before starting mounting, disassembly or wiring of the Bus Terminals. |
Contact assignment
Terminal point | No. | Connection for |
|---|---|---|
DALI + | 1 | DALI/DSI control cable (internally connected to terminal point no. 4) |
+24 V | 2 | Power contact +24 V |
0 V | 3 | Power contact 0 V |
DALI + | 4 | DALI/DSI control cable (internally connected to terminal point no. 1) |
DALI - | 5 | DALI/DSI control cable (internally connected to terminal point no. 8) |
+24 V | 6 | Power contact +24 V |
0 V | 7 | Power contact 0 V |
DALI - | 8 | DALI/DSI control cable (internally connected to terminal point no. 5) |
Note | |
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 under 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!
Cable length | Wire cross section |
|---|---|
up to 100 m | minimum 0.5 mm2 |
up to 150 m | minimum 0.75 mm2 |
up to 300 m | minimum 1.5 mm2 |
Further important boundary conditions derived from IEC 62386:
- The DALI cables must not be terminated with resistors.
- The maximum voltage drop between the sender and the receiver must not exceed 2 V.
- If the maximum cable length is utilized, it is not advisable to lay DALI in combination with the power cable.
