4.2.2.3 Cross-section of the supply cable
The conductor cross-section of the supply cable is dependent on the input current, the
cable according to manufacturer's data, as well as the VDE regulations.

4.2.4 connection of the motor
4.2.4.1 Selection of the motor cable
The correct cabling as well as the motor cable play an important part in case of low pow-
er in connection with long motor line lengths. Ferrite cores and low-capacitance cables
(phase/phase < 65 pF /
m, phase/screen < 120 pF / m) at the output have the following
effects:
• Longer motor line lengths
• Less abrasion of the motor gearbox by leakage currents
• Better EMC properties
