In terms of operating safety, the ground connection helps prevent the occurrence of dangerous voltage
between parts that are accessible at the same time, up to frequencies for which the ground connection
(solely designed for the safety of individuals) can be considered low impedance.
Therefore, at high frequencies (over a few tens of MHz) the impedance of the ground connection is
completely unpredictable, and there is no guarantee of protection at high frequencies.
WARNING
Always make sure that the electrical system has a ground connection and that the ground
connection functions.
Do not disconnect the ground for any reasons.
