Checklist when the luminaire does not ignite or work correctly

1. The luminaire does not ignite?

• Is the luminaire installed and connected in accordance with the installation instructions?
• Is the correct driver connected to the luminaire?
• Has the luminaire been connected to the driver before connecting the mains voltage?
• Check the supply voltage in the luminaire's terminal block.
• Is + and - connected correctly between luminaire and driver?
• Switch off the power and turn it on again!
  
  

2. The earth-fault breaker or fuse trips when the lighting is igniting?

• There could be an earth fault or short circuit in the luminaire group.
• Too many luminaires in the same circuit, please refer to the product sheet.
• A measurement instrument connected incorrectly to the power circuit can trip an earth-fault breaker.

3. The fluorescent lamp’s cathode glows, but the lamp doesn’t ignite?

• Mains voltage too low. Measure the voltage on the luminaire.
• The starter in a luminaire with a conventional ballast could be defective.
• There is a fluorescent lamp in the luminaire with the wrong output/type or wrong HF-ballast.
  
  

4. There is a problem with the dimming system?

• Always check before connecting that the luminaires are intended for the control unit used.
