Pin 8

VCC

Supply voltage

to apply the power supply directly by mains with dropping resistor and backup capacitor.

The current feed should be choiced high enough for the operation of the voltage limiting.

Only under these conditions a proof error storage and a defined reaction of the turn-off transistor is guaranteed.
