Arrangement of the wiring

Strictly observe the frequency inverter manufacturer's installation recommendations and requirements! Observe the following in particular:

• The power cable between frequency inverter and compressor motor should have a suitable EMC shield which is connected to both the mounting plate of the electrical enclosure and to the body of the motor with large contact-area bonding of the screen without any “pigtail” connections.
• Depending on the local environment (residential, commercial, industrial etc.), additional EMC filters may be required.
• The motor should be earthed using the protective earth conductor of this cable.
• Additionally, the compressor housing should be earthed separately with a cable of suitable cross-sectional area.
• With regard to the power cable, the frequency inverter m
• anufacturer's recommendations should be observed (e.g. concerning maximum length, spacing to other cables).
