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 1.8.1 Mains Supply
3x380-480 V AC.
•
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 instruction, FC 101
Mounting of decoupling plate for H1 and H2.
•
Also see EMC-Correct Installation in the Design
Guide.
1. Mount the earth wires to earth terminal.
2. Connect motor to terminals U, V and W.
3. Mount mains supply to terminals L1, L2 and L3
and tighten.
