4.3.1. Mounting of the Power Supply Filter
In order to fulfill EMC requirements, one must always apply the delivered power
supply filter when connecting the supplying wire to the analyser.
To mount the power supply filter one must reeve all the three supplying wires
(L,N,PE) through the filter core, creating a full loop around it (Fig.4.4).
