WARNING - CAUTION
As you can see at the picture the pcb will be at mains potential and therefore lethal. You must insure that this pcb is well protected against unintentional touching. All parts are dangerous to touch when the mains is switched on.
If you can, use a 0-5 V DC source to test the diode function. If it works all right with low DC voltage then test with 230 VAC.
The DC trap is ready.
