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
• EN60204-1 Safety of machinery – Electrical equipment of machines
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 adhesive label is removed from the top of the drive, 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.
• PowerFlex drives may cause radio interference if used in a
residential or domestic environment. The user is required to take
measures to prevent interference, in addition to the essential
requirements for CE compliance listed below, if necessary.
• 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.
Essential Requirements for CE Compliance
Conditions 1-4 listed below must be satisfied for PowerFlex drives to
