Input power (mains) cable
The following table gives copper and aluminium cable types for
different load currents. These recommendations apply only for
the conditions listed at the top of the table.
Dimension the cables according to local safety regulations,
appropriate input voltage and the load current of the drive. In
any case, the cable must be less than the maximum limit defined
by the terminal size (see section Input power and motor
connection terminals on page 402).
