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.
