•
The PowerFlex 700L Frame 1X drive generates harmonic current
emissions on the AC supply system. When operated on a public network
it is the responsibility of the installer or user to ensure that applicable
requirements of the distribution network operator have been met.
Consultation with the network operator and Rockwell Automation may
be necessary.
Installation Requirements Related to EN 50178 and the Low Voltage Directive
•
The insulation system of the 480V PowerFlex 700L Frame 1X drive is
designed to be CE compliant when connected to either “center-earthed”
supply systems or “corner-earthed” supply systems for altitudes up to
and including 2000 m (6525 ft).
•
When used at altitudes above 2000 m (6525 ft) up to a maximum of
5000 m (16,404 ft), PowerFlex 700L Frame 1X drives may not be
powered from a “corner-earthed” supply system in order to maintain
compliance with the CE LV Directive.
•
The PowerFlex 700L Frame 1X drive 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 in
Table 2 .
Table 2 Pollution Degree Ratings According to EN 61800-5-1
•
The PowerFlex 700L Frame 1X drive must be installed in a
supplementary enclosure to be CE compliant with respect to protection
against electrical shock.
•
The PowerFlex 700L Frame 1X drive produces touch 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.
!
ATTENTION: PowerFlex 700L Frame 1X drives produce DC
current in the protective earthing conductor which may reduce the
ability of RCDs (residual current-operated protective devices) or
RCMs (residual current-operated monitoring devices) of type A
or AC to provide protection for other equipment in the
installation.
Pollution
Degree
Description
1 No pollution or only dry, non-conductive pollution occurs. The pollution has no
influence.
2 Normally, only non-conductive pollution occurs. Occasionally, however, a temporary
conductivity caused by condensation is to be expected, when the drive is out of
operation.
3 Conductive pollution or dry non-conductive pollution occurs, which becomes
conductive due to condensation, which is to be expected.
4 The pollution generates persistent conductivity caused, for example by conductive
dust or rain or snow.
