4.5 Connecting the RF Reference Ground

The V-network is connected to the PE protective earth conductor of the power supply
through the protective earth conductor terminal. However, this is unsuitable as an RF
reference mass for interference voltage measurement. Therefore, the V-network must
be connected to an appropriate RF reference ground to obtain reproducible and correct
measurement results.

The RF reference mass used be connected over a wide metal sheet with eleven M6
screws (1) flatly to the side-installed ground bar (see
