Description of the devicesInstruction handbook Mains filters BFNDocument No.: 5.09010.0335of 7044.1 General informationMains filters are combinations of capacitors, chokes, resistors and voltage limiters, whichreduce the electromagnetic influence of environment. The power direction is bidirectional,i. e. the outgoing cable-guided faults from the converter are reduced, but also the inter-ference resistance of the drive against supply faults, as they appear with lightning strokes,fuse blow or simple switching operations, is improved at the same time.The mains filters of the series BFN ... were developed for the BAUMÜLLER-power elec-tronics referring to its attenuation behavior. Its application enables the compliance withthe limitation values which are required for the branch of industry (second environment)of the EMC product standard for variable-speed electrical power drive systemsEN 61800-3 as well as the „Generic Standards“ EN 61000-6-4.When using the filter series BFN ... in the combination with Baumüller converters,Baumüller-motor cables and Baumüller motors and under consideration of the installa-tion- and mounting notes in this Instruction Handbook and in the Instruction Handbook ofthe power converter, the protection requirements of the European EMC Directive and ofthe EMC Act (EMVG) accordant to §3, sec. 1 are fulfilled.NOTE!The emission of radio interferences is to a high level dependent of the wiring, the vol-ume expansion and the arrangement of the components in the installation. This iswhy the ensuring of the EMC according to the legal regulations only is possible withthe completed installation and therefore is in the responsibility range of the manufac-turer of the installation or of the operating authority. (EMVG § 6, sec. 9).NOTE!Components of the Baumüller Nürnberg GmbH are intended for installation in com-mercially available control cabinets.There are several reasons to operate the components and devices in commercialcontrol cabinets. Particularly the following is ensured:m The required contact protection is ensured.m The thermal environmental conditions (temperatures, relative humidity, cleanli-ness of the coolants, ...), described in the technical data of the components andthe devices, are ensured.m The mechanical environmental conditions described in the technical data of thecomponents and the devices (variations, vibrations, ...), are ensured.m The notes meeting the EMC-configuration and the EMC-structure (shielding con-cept, laying principles, implementations,...) described in the technical data of thecomponents and devices can be implemented.
