That's what I saw on the RS photo

sounds like it, presume it now has "that smell"?

Well, I wasn't talking about the order of the connections, merely their 
labels, you should have brown to L, blue to N, and green/yellow to GND

with perhaps red(?) to +V and black(?) to -V on the output side.

No couldn't smell anything as the CU tripped immediately I plugged it in .
I'll re  do it and try again later now.

Wiring it L,N and GND helps. It powers up ok, but there is no output so 
something has gone on the inside when I wired it incorrectly.

I would have said I wasn't surprised it died ... except if I read the 
specs correctly it should withstand 500V AC applied to the output for 60 
seconds?  Maybe that's only when applied from +V to GND, not +V to -V
