What is the lug/connection in the bottom right corner for? See image. Mentioned no where in the manuals or the drawings.

What's the purpose of this bolt connection in my multiplus 24/5000?
I actually have the same question, in the manual of the Multiplus under annex A, the primary ground connection is allocated to another location on the housing case, not to this bolt, has this been confirmed meanwhile that this bolt is indeed the ground connection?
Could be a common or an isolated ground depending on how the PCB is laid out (sometimes when PCB are laid out common connections are mirrored) you could put a multimeter between the two to check but as marked by the symbol on the PCB/Case or as directed by the manual this should always be used as the grounding point.
