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 "Cable Terminals" on page 129).
Note 2: Fuse Type: UL Class T. For non-UL installations IEC 269 gG.
