No. There's no requirement to earth it, there is a requirement for
equipotential bonding. I suggest getting yourself an "on-site guide"
which explains the difference. They're more often confused than
they're correctly understood.

Well, if my reading of the "on-site guide" is correct equipotential
bonding isn't required either.
