We are talking about the signal grounding and the input screening would be fine there.
The mains earth will be by the mains input and aught to have links to the output screening and the frames of the machine and the motor. These are the ones you check with a PAT tester.
The signal ground will lead to the power earth but is not going to be thick enough for anything else.
