1.3.5 Connecting to Mains and Motor

The frequency converter is designed to operate all
standard three-phased asynchronous motors. For
maximum cross-section on wires see 1.6 General Specifi-
cations.
•
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 MI02Q.
•
Also see EMC-Correct Installation in the VLT
Basic Design Guide, MG18C.
1. Mount the earth wires to earth terminal.
