Electromagnetic Compatibility (EMC)
To ensure that the common DC link system complies with electromagnetic compatibility
(EMC) rules and does not interfere with other systems, obey the following guidelines:
• Obey the electrical installation instructions in the drive hardware manual.
• To minimize the conducted emissions, order a relevant EMC filter option for the drive
that will be connected to AC power line. See the drive hardware manual for the
possible EMC filter options.
• To minimize the radiated emissions:
• Keep the power cable runs as short as possible. Especially important is to keep
the DC cabling and the brake resistor cabling short.
• Make 360-degree grounding of the cable shields at the drive cable connection
box, using either a metal gland or the clamps supplied. If you install the drives
inside a cabinet, make the 360 degree earthing at the cabinet cable entry.
• Use shielded power cables.
For more information of the general EMC guidelines, see Technical guide, EMC compliant
installation and configuration for a power drive system (3AFE61348280 [English]).
Note: ABB has not tested the various common DC systems against the EMC product
standard (EN 61800-3:2004) requirements stated for drives. An EMC plan may be
required to gain CE compliance.
