Hi Tad,
We posted the original netPI schematics years ago in this thread: https://forum.hilscher.com/thread-253.html
There you see that PE pin goes to the metallic chassis only and is connected to + and - via protecting varistors.
The PE pin is exclusively made for those use cases when there is no guarantee that the DIN rail where the netPI is ususlly attached on is connected to PE. In this case you can use a cable with the PE pin and put/ground netPI to PE "manually".
So if customers DIN rail is put to PE already there is no need to use the PE pin.
Thx
Armin
