Disassembly

WARNING: Before disassembling, please cut off the power supply, and strictly prohibit operation with electricity.

Operation

1. Use with controllers
   For use with Buspar-DALI Controller or KNX-DALI Controller.
   The DALI controller automatically assigns a DALI address code, one DALI address code can control the output of one device, please refer to the instruction manual of the DALI controller for details.
2. Use with NFC configuration tool.
   Note
   1. Please make sure the wiring is correct according to the wiring diagram.
   2. It is recommended to set the parameters without powering on the DALI device.
   3. Please make sure your mobile phone has NFC function and enable it.
      For details, please refer to the commissioning instruction board.
