Input power (mains) cable
Dimension the cables according to local safety regulations,
appropriate input voltage and the load current of the drive.
Note: The cable must be less than the maximum limit defined by
the terminal size. Check the maximum wire size according to the
table in section Input power and motor connection terminals on
page 408.
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.

• EN 60204-1 and IEC 60364-5-2
• PVC insulation
• 30 °C (86 °F) ambient temperature
• 70 °C (158 °F) surface temperature
• cables with concentric copper shield
• not more than nine cables laid on cable
ladder side by side.
Based on:
• NEC Table 310-16 for copper
wires
