EMC Instructions

CE Conformity

Conformity with the Low Voltage (LV) Directive and Electromagnetic
Compatibility (EMC) Directive has been demonstrated by using harmonized
European Norm (EN) standards published in the Official Journal of the
European Communities. PowerFlex Drives

(1)

comply with the EN standards

listed below when installed according to the information supplied in this
publication and the Wiring & Grounding Guidelines Manual.

CE Declarations of Conformity are available online at:

http://www.rockwellautomation.com/rockwellautomation/certification.

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

Some drives are equipped with an adhesive label on the top of the drive. 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 must be kept as short as possible to avoid electromagnetic
emission as well as capacitive currents.

Use of line filters in ungrounded systems is not recommended.

PowerFlex drives can cause radio frequency interference if used in a
residential or domestic environment. The installer 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.

When operated on a public supply system, it is the responsibility of the
installer or user to ensure, by consultation with the distribution network
operator and Rockwell Automation, if necessary, that applicable
requirements have been met.

(1) 600V class drives below 77A (Frames 0…4) are declared to meet the essential requirements of the Low Voltage Directive. It is the

responsibility of the user to determine compliance to the EMC directive.
