-Warning: when you are making projects that are connected to mains voltage, you really need to know what you are doing, otherwise you may shock yourself. This is a serious topic, and we want you to be safe. If you’re not 100% sure what you are doing, do yourself a favor and don’t touch anything. Ask someone who knows!

 You need to slice the cable and cut the single phase line (L), in my case this was the brown cable. One end should connect to COM (common), and the other to NO (nominally open).
