Special issues when connecting inverters, frame sizes FSA, FSB and FSC equipped with Profinet
Control Units to the line supply
If you are using a PROFINET Control Unit, then you must
connect the line supply via two ferrite cores; e.g. "Würth
742 - 712 - 22" or equivalent versions.
Special issues when connecting inverters, frame sizes FSB, FSC and FSD equipped with external
filter B to the line supply
If you are using a Class B EMC filter, then you must con-
nect the filter for the Power Modules, frame sizes FSB,
FSC and FSD, to the line supply via two ferrite cores.
For frame sizes FSB and FSC ferrite cores, type "Würth
742 - 712 - 22" or equivalent are suitable.
You require ferrite cores, type "Würth 742 - 701 - 91" or
equivalent, for frame size FSD.
The ferrite cores are required in addition to the EMC
measures in order to attain EMC Category C2.
