Note 1: Mains cable sizing is based on a correction factor of 0.71
(maximum of 4 cables laid on a cable ladder side by side, ambient
temperature 30°C (86°F), EN 60204-1 and IEC 364-5-523). For other
conditions, 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 between the minimum limit defined in this table and the
maximum limit defined by the terminal size (see section
page 383.)
