PowerFlex 700S Adjustable Frequency AC Drive - Phase II Control
General Considerations
• 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 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 installer is required to take
measures to prevent interference, in addition to the essential requirements
for CE compliance provided in this section, 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.
• More information regarding harmonic emissions can be found in the
PowerFlex 700S AC Drives Phase II Control, Reference Manual,
publicatio
• When operated on a public supply system, it is the responsibility of the
installer or user to be sure, by consultation with the distribution network
operator and Rockwell Automation, if necessary, that applicable
requirements have been met.
Essential Requirements for CE Compliance
Conditions 1…6 listed below must be satisfied for PowerFlex 700S Phase II
drives to meet the requirements of EN61800-3.
1. Standard PowerFlex 700S CE compatible drive.
2. Review important precautions/attentions statements throughout this
document before installing drive.
3. Grounding as described in Grounding Requirements on page
4. Output power, control (I/O) and signal wiring must be braided, shield
cable with a coverage of 75% or better, metal conduit or have shielding/
cover with equivalent attenuation.
5. All shielded cables should terminate with proper shielded connector.
