Input power (mains) cables and fuses
A four conductor cable (three phases and ground/protective
earth) is recommended for the input power cabling. Shielding is
not necessary. Dimension the cables and fuses in accordance
with the input current. Always pay attention to local codes when
sizing the cables and fuses.
The input power connectors are at the bottom of the drive. Input
power cable routing must be done so that the distance from the
sides of the drive is at least 20 cm (8 in) to avoid excessive
radiation to the input power cable. In the case of shielded cable,
twist the cable screen wires together into a bundle not longer
than five times its width and connect to the PE terminal of the
drive. (Or PE terminal of input filter, if present.)
Line current harmonics
The current harmonic levels under rated load conditions are
available on request.
