Technical data43Note: A professional is a person or organisation having necessary skills in installing and/orcommissioning power drive systems, including their EMC aspects.Category C2 has the same EMC emission limits as the earlier class first environment restricteddistribution. EMC standard IEC/EN 61800-3 does not any more restrict the distribution of the drive, butthe using, installation and commissioning are defined.Drive of category C3: drive of rated voltage less than 1000 V, intended for use in the secondenvironment and not intended for use in the first environment.Category C3 has the same EMC emission limits as the earlier class second environment unrestricteddistribution.Compliance with the IEC/EN 61800-3 (2004)The immunity performance of the drive complies with the demands of IEC/EN 61800-3, secondenvironment (see page 42 for IEC/EN 61800-3 definitions). The emission limits of IEC/EN 61800-3 arecomplied with the provisions described below.First environment (drives of category C2)1. The optional EMC filter is selected according to the ABB documentation and installed as specified inthe EMC filter manual.2. The motor and control cables are selected as specified in this manual.3. The drive is installed according to the instructions given in this manual.4. Motor cable length maximum 30 m (100 ft) with 4 kHz switching frequency.WARNING! In a domestic environment, this product may cause radio inference, in which casesupplementary mitigation measures may be required.Second environment (drives of category C3)1. The internal EMC filter is connected (the metal screw at EMC is in place) or the optional EMC filteris installed.2. The motor and control cables are selected as specified in this manual.3. The drive is installed according to the instructions given in this manual.4. With the internal EMC filter: motor cable length 30 m (100 ft) with 4 kHz switching frequency.WARNING! A drive of category C3 is not intended to be used on a low-voltage public network whichsupplies domestic premises. Radio frequency interference is expected if the drive is used on such anetwork.Note: It is not allowed to install a drive with the internal EMC filter connected on IT (ungrounded)systems. The supply network becomes connected to ground potential through the EMC filter capacitorswhich may cause danger or damage the drive.Note: It is not allowed to install a drive with the internal EMC filter connected on a corner grounded TNsystem as this would damage the drive.
