*) Synchronisation with the mains can only occur if a load is connected!
WARNING
Risk of electric shock!
With the Sync LED switched off mains voltage may still be present at the KL2751 output! At
this time automatic load detection and synchronisation have not yet been carried out!
Automatic load detection display
After the load detection (shortly after the mains voltage has been switched on) the terminal signals the load
type and the selected operation mode via the LEDs.
• LED sequence green / red: Trailing edge phase control for resistive or capacitive load
• LED sequence green / red: Leading edge phase control for inductive load
