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
reactor must be the same in case of parallel connection of R6-S with different sizes.
2) Mains- and DC fuses must be monitored.
