CE Conformity 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 and Reference Manuals.
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 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 frequency 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 or installation complies with CE EMC requirements. Many
factors can influence total machine/installation compliance.
•
PowerFlex drives can generate conducted low frequency disturbances
(harmonic emissions) on the AC supply system.
Essential Requirements for CE Compliance
Conditions 1-6 listed below must be satisfied for PowerFlex drives to meet the
requirements of EN61800-3.
1. Standard PowerFlex CE compatible Drive.
2. Review important precautions/attention statements throughout the User
Manual before installing the drive.
3. Grounding as described on page 107 .
4. Output power, control (I/O) and signal wiring must be braided, shielded
cable with a coverage of 75% or better, metal conduit or equivalent
attenuation.
5. All shielded cables should terminate with the proper shielded connector.
6. Conditions in the appropriate table ( 5 , 6 or 7 ).
