1) If the inverter current > current of the COMBIVERT R5‑S it must be wired at an external terminal (6).
The cable cross‑section may not be smaller than 10 mm². It must be dimensioned for the DC rated current of the load. Otherwise there are fuses
2)
in the DC link circle (7) necessary The indicated maximum protection for the connected frequency inverters must be observed !
3) In case of parallel connection of R6‑S the total power can be smaller up to 15 % caused by production tolerances of the commutation choke. The
impedance voltages uk of the commutation chokes must be the same in case of parallel connection of R6‑S with different sizes.
