common ground for shielding etc

[CNCModeller]

Hi All,
Where is the best place to connect a duet ethernet / Duet 3 Mini for common ground for cable shielding?

I assume its the -ve power input? Not that I know any better but I want to try and do my build as well as I can.

My Wanhao D5s used foil wrap on the display ribbon cables earthed to the common ground. Is this a good idea here too?

Any constructive thoughts would be much appreciated.

All the best
Barry M
