Set it on a cardboard box. (With a sticky note warning not to touch case...)

I'll probably just float the ground.

They are hard to find. Where will you ground the MT in this type of scenario
(with an RSD in between your -48V rectifier and MT)?

It actually looks like the RSD-100C-24 should do the trick (I'm dropping to
24v, so I guess my subject line wasn't exactly correct). My normal source is
out of those, according to their website they have some RSD-200C-48 units
though.

The Mean Well RSD gives 4kV i/o isolation and will work perfectly this,
no grounding issues. I think the smallest you can get in 48/48 is 200W, the
RSD-200C-48. Good luck finding some.

I'm wanting to power a mikrotik switch off of a -48v rectifier setup
that already has some -48v equipment running on it. I'll be using a Meanwell
DC/DC converter, which appears to not bond anything with the ground. The
mikrotik, however, does bond the negative with ground. Do I need to keep the
mikrotik's ground isolated from the main ground? Or is the DC/DC converter
going to keep things from going boom?
