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
Drive’s power connection terminals
on page
).
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.
