WIRING AND CONFIGURATION OF THE ECG
4.1.3. Connection via power-line converter
If the power line is used to transmit the DALI
® signal to the
luminaire, a power-line-to-DALI ® converter is required to
control the 3DIM ECGs.
In order to ensure proper power line communication, a
fi lter might be necessary to decouple the low mains input
imped ance of the ECG from the power-line-to-DALI
®
converter.
Note: The used power line to the DALI ® converter should
provide at least the same surge withstand capability as the
3DIM ECG.
