Rockwell Automation 23P PowerFlex Digital DC Drive - Manual (Page 40)

40 Rockwell Automation Publication 20P-UM001K-EN-P - July 2014
Chapter 1 Installation and Wiring
Installation Requirements Related to the Low Voltage Directive
• PowerFlex DC drives are designed to be CE compliant only if they are NOT
connected to “corner-earthed” supply systems where one of the three phases of
the supply system has been earthed.
• PowerFlex DC drives are compliant with the CE LV Directive when used at
altitudes no greater than 2,000 m (6,562 ft).
• PowerFlex DC drives provided in enclosure type IP20 must be installed in a
pollution degree 1 or 2 environment to be compliant with the CE LV
Directive. Characteristics of the different pollution degree ratings are
provided on
page 41 .
• PowerFlex DC drives can produce leakage current in the protective earthing
conductor that exceeds 3.5 mA AC or 10 mA DC. The minimum size of the
protective earthing (ground) conductor that is used in the application must
comply with local safety regulations for high-protective earthing conductor
current equipment.
• Frame D PowerFlex DC drives must be installed in a supplementary enclosure
that provides protection from electric shock to be compliant with the CE LV
Directive.
Installation Requirements Related to EN 61800-3 and the EMC
Directive
• The drive must be earthed (grounded) as described in this User Manual.
• PowerFlex DC drives require the use of an external EMC filter to comply with
the EMC Directive and emission limits of EN 61800-3: 2004. PowerFlex DC
drives have been tested and verified for compliance to the emission limits of
EN 61800-3: 2004 by using only the specific input filters and motor cable
lengths that are identified in
Table 9 . See Typical Power Wiring Diagrams on
page 45 for more installation information.
