EMC-compliant installation

The BLV brushless DC drive meets the EMC requirements for the second environ-ment as per IEC61800-3.An EMC-compliant design is required to maintain the specified limit values. Depen-ding in the case better results can be achieved with the following measures:•Upstream mains reactors. Information on current harmonics can be obtained on request.•Upstream external mains industrial filters, particularly to maintain limit values for the first environment (living area, category C2)•Particularly EMC-compliant design, e.g. in an enclosed control professional cabinet with 15 dB damping of radiated interference
