Primary;
"Blue and Brown will go to your 230V input. It doesn't matter here which one goes where. But I see the colour coding is the same as in Europe so just connect Blue to Blue and Brown to Brown."
Blue is negative and Brown is positive?
Secondary;
Red/Orange 0v
Black negative
Yellow 15v.
Sorry for so any questions but 240v hurts!
EDIT: also is the switch before or after the transformer?
With AC there is no such thing as positive and negative. In most modern house installations the standard is (L) Live - Brown and (N) Neutral - Blue.
For the transformer it doesn't really matter in fact as it is still AC.
If the switch is rated for 240V, you can put it before the transformer on the (L) Brown wire.
With regards to the secondary.
Yes, the Red/Orange will be your 0V center tap.
Both Black and Yellow will have 15V AC
Remember we are still at the transformer before rectifying, so until there all is AC. (Which doesn't have + or -)
Hope it helps.
Test Tip: Just wire the transformer up out of the case and not connected to the Yocto. Insulate all 240V connections. Plug it in and with a multimeter (Set for AC) measure between Red/Orange and Black, you should have more or less 15V AC. Measure between Red/Orange and Yellow and again you will have more or less 15V AC.
240V AC is indeed not to joke with, however if you take care and insulate all connections, there is no problem.
Worst thing that can happen is you blow a fuse in your house, release some magic smoke and maybe get a little zapp. Happened a lot to me when I was young and still experimenting, still the usual anecdote for my mother to tell at birthday parties, after I screwed something up and left the house in darkness..
Have a look at his videos, although he is crazy, you can learn a lot from him and he's still alive, however don't try this at home haha!
