On the back of it, there are connectors for 'L', 'E' and 'N'.
There are only the blue and brown wires coming out of the transformers primary coil, so I guess I don't connect anything to 'E'. Is that right?
'L' also connects to one side of the fuse, and has it's own terminal. There is another terminal for the other side of the fuse.
I think I have to connect the blue wire to 'N', and the brown wire to the terminal connected to the fuse. This means that I leave the terminal that is directly connected to 'L' alone. Am I right so far?
Lastly, the switch is DPST. Do I run both Active and neutral through the switch?
Thanks everyone. Sorry for asking such obvious questions, but I feel it's better to be safe than sorry when dealing with mains power for the first time.
