Chapter 1 General Installation Information
General Notes
• 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 700H or 700S CE compatible Drive. For Frames 10
and up, the drive must also be installed in a suitable Rittal TS 8 (or
equivalent) enclosure.
2. Review important precautions/attention statements throughout this
manual before installing the drive.
3. Grounding as described on page 21 .
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 Table 2 .
