5.9.2 Recommendation on Cable Dimensioning
1. Depends on the power of a frequency converter.
2. In table column “Nominal Current of Fuse [A]”, read corresponding information for
fuse.
1. The cable dimensions for inputs and outputs are based on supply
voltages of 1P 200 VAC / 3P 380 VAC.
2. For torque information, see the table below.
