Colleagues,
I’m designing a signal conditioning board for industrial environment. The board will reside inside a plastic enclosure on a DIN rail. I need EMI shielding. The enclosure will not provide shielding, because it’ plastic. I’m going to make a small sheet metal “can” that will be soldered onto the board. The question is: should I ground it to signal ground or earth ground (i.e. the DIN rail)?
Please let me know if I forgot to mention anything important.
Cheers,
Nick
