The question is how the cabinet is earthed if the PE wire goes to a
terminal block. If a wire comes out of the terminal block to a stud on
the cabinet, that is less reliable than a solid connection. I suggest
you take the advice. It doesn't apply if the 'terminal block' is not an
insulating block with metal inserts but a metal block firmly attached to
the cabinet.

A flexible 1-phase AC cable is entering a metal cabinet and the
PE-wire is directly connected to an Earth terminal block (green/yellow).
Some years ago, a safety engineer told me that the earth wire should
first be connected to a ground stud inside the cabinet via a lug
terminal climp and fastened with a nut. From the stud, a green/yellow
wire should connect to the Earth terminal block.
I thought it’s OK to go directly to the Earth terminal block, right? …
