■ EMC-correct electrical installation
General points to be observed to ensure
EMC-correct electrical installation.
- Use only screened/armoured motor cables and
screened/armoured control cables.
- Connect the screen to earth at both ends.
- Avoid installation with twisted screen ends (pigtails),
since this ruins the screening effect at high
frequencies. Use cable clamps instead.
- It is important to ensure good electrical contact from
the installation plate through the installation screws
to the metal cabinet of the frequency converter.
- Use starwashers and galvanically conductive
installation plates.
- Do not use unscreened/unarmoured motor
cables in the installation cabinets.
The illustration below shows EMC-correct electrical
installation, in which the frequency converter has been
fitted in an installation cabinet and connected to a PLC.
