A converter must always be connected to the line supply through a commutation inductance. This must have at least 4 % uK! The commutation inductance can be in the form of a converter transformer or, for the appropriate line supply, in the form of a commutating reactor.
A line supply can be considered to be "stiff" if the power ratio Ps/Sk ? 0.01. Even for stiff line supplies, the commutation inductance must have a uK of at least 4 %!
For high-rating converters, the line reactance, i.e. the finite fault level (short-circuit power) of the line supply must be taken into account; this also results in higher uK values. Recommendation for the ratio of the line supply fault level (short-circuit power) to the apparent drive power > 33:1.
The commutating reactors are dimensioned according to the rated motor current in the armature or field circuit.
Operation with line frequencies of 50 Hz and 60 Hz
The rated currents ILn of the reactors, specified in the table, apply for operation with a line frequency f = 50 Hz. It is permissible to operate the reactors with a line frequency f = 60 Hz. In this case, the next-higher voltage level must be selected (e.g. 480 V instead of 400 V).
At the same time, the voltage drop ?V increases by 8 %.
Arrangement of reactors and radio interference suppression filters
(1) The commutating reactor in the field circuit is dimensioned for the rated motor field current.
(2) The commutating reactor in the armature circuit is dimensioned for the rated motor armature current. The line current is 0.82 times the DC current.
(3) The radio interference suppression filter for the armature circuit is dimensioned for the rated motor armature current. The line current is 0.82 times the DC current.
(4) The radio interference suppression filter for the field circuit is dimensioned for the rated motor field current.
(5) The electronics power supply itself does not require a radio interference suppression filter. Current consumption 1 A at 400 V, 2 A at 230 V.
(6) If the power supply voltages for the armature circuit, field circuit and electronics power supply are the same, then the voltage for the field and electronics power supply can also be taken after the radio interference suppression filter for the armature circuit.

1) All commutating reactors with rated voltages VN ? 600 V to UL
Note: The commutating reactors are dimensioned according to the rated motor current in the armature and field circuits. When the unit is connected to a single phase, single-phase commutating reactors must also be used in the armature circuit. These are available on request.
The tables below list the commutating reactors which are available as standard. Additional information can be found in the Operating Instructions "SINAMICS DCM Commutation reactors" (see http://support.automation.siemens.com/WW/view/en/85062393).

2) Note about protection class 1: Despite protective conductor connection, no 'touchable conductive parts' with regard to the standard (e.g. EN 61800-5-1) are defined. In this case, the protective conductor ensures that no dangerous voltages/currents can act at the mounting surfaces. The complete reactor must be considered as being an active component.
