Samotech Pull Cord UK Wiring

Anyone using a samotech pull cord in the UK? No neutral required but the manual uses both N and L named cables for some reason.

I currently have a two way pull cord but it’s configured in one way. Common into COM (Live) then L2 connected to the light.

The wiring diagram from samotech isn’t clear how this is supposed to be connected. I tried using their one way connection method which didn’t work.

I’ve contacted the company to ask. But thought I would ask here too.
