Input power cables/wiring
Input wiring can be either:
• A four conductor cable (three phases and ground/protective earth) routed through
conduit.
• 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 Drive’s power connection terminals on page
1-307).
The table below lists copper and aluminum cable types for different load currents.
These recommendations apply only for the conditions listed at the top of the table.
IEC NEC
Based on:
• EN 60204-1 and IEC 60364-5-2/2001
