4.3.3 Emissions Compliance
An internal factory installed EMC filter is provided with all ratings, it is recommended
that it is kept in place unless there is a specific reason for removing it. This internal filter
reduces radio-frequency emissions into the line power supply. When the motor cable is
short, it permits the requirements of EN61800-3:2004 to be met for the second
environment with restricted distribution. For longer motor cables, the filter continues to
provide a useful reduction in emission level. When used with any length shielded motor
cable (up to the limit for the drive), it is unlikely that nearby industrial equipment will be
disturbed.
Installation of an additional external EMC filter as shown in Table 4-1, provides higher
levels of emissions compliance. If the application requires these levels of compliance
then the external filter must be installed in order to ensure compliance with EMC
regulations such as the EC EMC Directive, and to ensure the validity of the CE mark.
Table 4-1 Emmisions compliance for VFD66 based on EMC filter configuration
*The typical leakage current of the low leakage filter is 3mA compared to the standard
filter which has a typical leakage current of 40mA.
Table 4-2 Key to conformity
Notes:
(1) The first environment is one where the low voltage supply network also supplies
residential premises
(2) When distribution is restricted, drives are available only to installer with EMC
competence.
