That's a whole can of worms you have opened. I would do the same or
similar, I run in a Mains Earth free environment.
I am sure Andy knows what he is doing. In my case connecting the
'safety earth' would mean I was connecting? my antenna system to the
Neutral of the mains supply and also directly to the Neutral of the
next door house.
Under fault conditions (which did happen here) the chassis of the U2
could then rise to phase potential and huge current would sink to
Earth via the antenna system or via the operator.

I assume that's an incoming 240V mains cable feeding the
transformer. It looks as if you've chopped the earth wire
adjacent to the end of the outer jacket. As it's a metal
box, it needs the safety earth connecting. We'd hate to
lose you...
