chapter also contains the relevant technical data.
EMC standard
The EMC product standard (EN 61800-3:2004) covers the specific EMC
requirements stated for drives (tested with motor and cable) within the EU. EMC
standards such as EN 55011 or EN 61000-6-3/4 apply to industrial and household
equipment and systems including drive components inside. Drive units complying
with the requirements of EN 61800-3 are always compliant with comparable
categories in EN 55011 and EN 61000-6-3/4, but not necessarily vice versa.
EN 55011 and EN 61000-6-3/4 do neither specify cable length nor require a motor to
be connected as a load. The emission limits are comparable according to the
following table.
An external EMC filter of the type JFI-0x is required to meet the category C2 level
with the drive module installation, including a motor with a maximum 100 meters
cable. This level corresponds to the A limits for Group 1 equipment according to
EN 55011.
