I'm currently setting up an Multiplus II GX 48/3000 however the device has a primary ground connection.
The PE of the AC is shared with it (as expected) but is the primary ground connection required? I thought it might have been something depending on preference/setup you might want to earth it close to the device itself, but what I do like to know is there a specific reason from safety perspective?
I'm setting it up in home, so I already have AC in and out connected to earth; when looking at the manual they do not really say anything about Primary ground connection, so my initial guess was it's not important but I'm not here to guess, if it has a specific purpose for DC I might have a bad time*
