EMC Directive. The end user takes personal responsibility
for the EMC compliance of the whole installation. However,
when installed according to the recommendations described
in the product manual and including the recommended filters
and EMC measures the CFW-10 fulfill all requirements of the
EMC Directive (89/336/EEC) as defined by the EN61800-3
"EMC Product Standard for Adjustable Speed Electrical
Power Drive Systems - specific standard for variable speed
drives.
The conformity of the complete CFW-10 series is based on
tests performed on sample models. A Technical Construction
File (TCF) was prepared, checked and approved by a
Competent Body.
