1) 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 in the DC circuit (10) necessary The indicated maximum
protection for the connected frequency inverter must be observed!
2) If the inverter current > current of the COMBIVERT R6-S it must be wired at an external terminal (12).
3) The contactor may only be connected if the precharging in the DC circuit is completed. Note the per-
missible DC link capacity of the charging circuit of the inverter!
