• Use of line filters in ungrounded systems is not recommended.
• 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.
• Non-regenerative PowerFlex 700L Liquid-Cooled AC drives generate
conducted low frequency disturbances (harmonic emissions) on the AC
supply system which may require mitigation in some applications. More
information regarding harmonic emissions can be found in the
PowerFlex 70/700 Reference Manual, publication PFLEX-RM001.
• When operated on a public supply system, it is the responsibility of the
installer or user to make 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 through 6 listed below must be accomplished for a
PowerFlex 700L drive installation to meet the requirements of EN61800-3.
1. Use a standard PowerFlex 700L Liquid-Cooled CE-compliant drive.
For the Frame 2 drive, kit Catalog Number SK-L1-CHK2-F2, which
includes common mode chokes and shielded cable clamps, must be
installed according to its included instructions, publication 20L-IN011.
For Frame 3A and 3B, the drive must be installed in a suitable enclosure
which attenuates radio frequency emissions (Rittal TS 8 or equivalent).
2. System grounding as described on page 1-2 .
3. Output power wiring to the motor, control (I/O) and signal wiring must
use cable with a braided shield with coverage of 75% or greater, or
cables must be contained in metal conduit, or equivalent shielding must
be provided.
4. All control (I/O) and signal wiring to the drive must use cable with a
braided shield providing 75% or greater coverage, or the cables be
housed in a metal conduit, or equivalent shielding must be provided.
When shielded cable is used, only the drive end of the cable shield
should be terminated with a low-impedance connection to earth.
5. The shields of all shielded cables must be terminated with the proper
shielded connectors to chassis/earth.
6. Motor cables must not exceed 20 meters (65.6 feet) in length.
7. Motor cabling must be separated from control and signal wiring
wherever possible.
8. Review important precautions and attention statements throughout this
manual before installing the drive.
