EMC Instructions

The following section provides instructions for Electromagnetic Compatibility
(EMC) compliance.

CE Conformity

(1)

Conformity with the Low Voltage (LV) and EMC directive has been
demonstrated by 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 manuals
and reference manuals.

CE declarations of conformity are available online at:

overview.page

Low Voltage Directive (2006/95/EC)

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, 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.

Use a motor cable that is as short as possible to avoid electromagnetic

emission and capacitive currents.

Do not use line filters in ungrounded systems.

PowerFlex drives can cause radio interference if used in a residential or

domestic environment. Follow national and local industrial safety
regulations and/or electrical codes, in addition to the essential
requirements for CE compliance (see

page 9

), to prevent radio

interference.

Conformity of the drive with CE EMC requirements does not mean that

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. More information
regarding harmonic emissions can be found in the PowerFlex Reference
Manual, publication

PFLEX-RM004.
