1) Mounted side-by-side, with no additional cooling area
2) Mounted side-by-side, with backplane (940 mm x 70 mm = 0.065 m²) as additional cooling area
3) inverter module With Heat sink “HS32.200”
4) The rated current with a 25 m motor cable is less than that with a 10 m motor cable by the amount of the current loss occurring on the motor
cable (see table 3.2.7)
