Input power cables/wiring
Input wiring can be any of:
• a four conductor cable (three phases and ground/protective earth). Shielding is
not required.
• four insulated conductors routed through conduit.
Size wiring according to local safety regulations, appropriate input voltage and the
drive's load current. In any case, the conductor must be less than the maximum limit
defined by the terminal size (see section
276).
The table below lists copper and aluminium cable types for different load currents.
These recommendations apply only for the conditions listed at the top of the table.
Based on:
• EN 60204-1 and IEC 60364-5-2/2001
• 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.
