CONNECTION OF THE POWER UNIT
4.2.3.2 Supply line
The conductor cross-section of the supply line is determined by the following factors:
• Input current of the drive converter
• Used cable type
• Installation method and ambient temperature
• The locally valid electrical regulations
The project engineer is responsible for the design!
