1) In case of parallel connection of R6-S the total power can be smaller up to 10 % caused by pro-
duction tolerances of the commutation reactor. The impedance voltages uk of the commutation
chokes must be the same in case of parallel connection of R6-S with different sizes.
2) Parallel connection of the frequency inverter and R6-S causes a circulating current in regenerative
operation. It is depending on the inductance of the mains choke. The entire regenerative power is
75...90 % of the R6-S regenerative power.

The cable cross section as well as the DC fuses (see chapter 2.1) must
be dimensioned to the DC rated current of the load (see technical data of
the inverter).
