EMC Instructions
CE Conformity
Conformity with the Low Voltage (LV) Directive and Electromagnetic
Compatibility (EMC) Directive has been demonstrated using
harmonized European Norm (EN) standards published in the Official
Journal of the European Communities. PowerFlex Drives comply with
the EN standards listed below when installed according to the User
Manual.
CE Declarations of Conformity are available online at:
http://www.ab.com/certification/ce/docs.
Low Voltage Directive (73/23/EEC)
• EN50178 Electronic equipment for use in power installations
EMC Directive (89/336/EEC)
• EN61800-3 Adjustable speed electrical power drive systems Part 3:
EMC product standard including specific test methods.
General Notes
• If the plastic top panel is removed or the optional conduit box is not
installed, the drive must be installed in an enclosure with side
openings less than 12.5 mm (0.5 in.) and top openings less than 1.0
mm (0.04 in.) to maintain compliance with the LV Directive.
• The motor cable should be kept as short as possible in order to avoid
electromagnetic emission as well as capacitive currents.
• Use of line filters in ungrounded systems is not recommended.
• Conformity of the drive with CE EMC requirements does not
guarantee an entire machine installation complies with CE EMC
requirements. Many factors can influence total machine/installation
compliance.
