FC101 Design Guide

5.1.1 Mains and Motor Connection

The frequency converter is designed to operate all

standard 3-phase asynchronous motors. For maximum

cross-section on cables, see chapter 8.4 General Technical

Data.

•

Use a shielded/armored motor cable to comply

with EMC emission

specications and connect

this cable to both the decoupling plate and the

motor.

•

Keep the motor cable as short as possible to

reduce the noise level and leakage currents.

•

For further details on mounting the decoupling

plate, see FC 101 Decoupling Plate Mounting

Instruction.

•

Also see EMC-Correct Installation in

chapter 5.1.2 EMC-compliant Electrical Installation.

converter to mains and motor, see chapter
