2 Internal RFI filter (MMX…F_), category C2 and C3, in accordance with IEC/EN 61800-3
EMC connection of internal RFI filter with PE.
3 Rectifier bridge, single-phase (MMX1_) or three-phase (MMX3_), converts the AC voltage of the electrical network into DC voltage
4 DC choke, DC link choke (only for MMX32…F_ and MMX34…F_ in frame sizes FS4 and FS5)
5 DC link with charging resistor, capacitor and switching-mode power supply unit
