Installation and Wiring
Chapter 1
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 2000 m (6562 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
.
• PowerFlex DC drives may produce leakage current in the protective earthing
conductor which exceeds 3.5 mA AC and/or 10 mA DC. The minimum size
of the protective earthing (grounding) conductor 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
which provides protection from electric shock in order 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 in order to
comply with the EMC directive (2004/109/EC) 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 using only the
specific input filters and motor cable lengths indicated in the table below:
