3.6 Reference ground

Operating Manual 5201.6693.14 - 03.00
The network is connected to the PE grounding connection for the mains power supply
through the mains cable, but this is not adequate for use as a reference ground in HF
noise voltage measurement.
The reference ground used can be attached flat to the grounding rail (2) on the side of
the device by a broad sheet metal with three metric M4 screws (1).

Grounding rail on the side of housing
In order to prevent RF interference emitted by the mains grounding conductor from
reaching the reference mass, the grounding conductor and the reference mass are
decoupled by a PE-choke. This choke should not be bridged by the EMI test receiver,
which is also connected to the measurement reference ground. Therefore, either an
isolated or a battery-powered receiver must be used, or a PE choke must also be
placed on the PE connection of the receiver.
