Overview
SINAMICS DC MASTER applications are in compliance with the
EMC product standard EN 61800-3 for electric drives when
taking into account that the units are integrated into the plant
or system in compliance with EMC rules.
However, EMC legislation does stipulate that the plant or system
as a whole must be electromagnetically compatible with its
environment.
If radio interference suppression level "A1" according to
EN
55011 is to be achieved, then in addition to the commutating
reactors, radio interference suppression filters are also required.
Radio interference suppression filters reduce radio interference
voltages of the converter that occur in conjunction with the
commutating reactor.
Radio interference suppression filters generate leakage cur-
rents. In accordance with DIN VDE 0160, a PE connection with a
cross-section of 10 mm
2
is required. For the filters to have opti-
mum effect, it is absolutely essential that they and the unit are
installed on a single metal plate.
For converter units with three-phase connection, the minimum
rated filter current is equal to the DC output current of the unit
times 0.82. For a two-phase connection (field power section or
single-phase connection of the armature power section) only two
phases are connected to the three-phase radio interference
suppression filter. In this case, the line current is equal to the field
DC current.
