Specifications

5.2.2 Connecting to Mains and Motor
The frequency converter is designed to operate all
standard 3-phased asynchronous motors. For maximum
cross-section on wires see 8.2 General Specifications.
Use a shielded/armored motor cable to comply
with EMC emission specifications, and connect
this cable to both the decoupling plate and the
motor metal.
Keep motor cable as short as possible to reduce
the noise level and leakage currents.
For further details on mounting of the
decoupling plate, see FC 101 De-coupling Plate
Mounting Instruction.
