Arduino Nano + 2 IR proximity Sensors + 4Channel 230V Relay -> Reset problem

Wawa:
No, an Uno/Mega has an (auto)resetable polyfuse.
A Nano has a tiny 500mA backflow protection diode (that burns when overloaded).

Relay link is a useless sales pdf. No real info there.
And they have hidden the most important side.
Were does it say the board is mains (230AC) rated?

Post a diagram.
Leo..

Here's link to fritz

First time using it, so couldn find all. unmarked wires going to relay are mains 230V, and NO output wires go to ac fan motor (chan1-3) and chan4 to a Led driver (ac to 12V)

EDIT: in the relay itself is says 250V 10A
