Installation Requirements Related To En 61800-5-1; And The Low Voltage Directive - Allen-Bradley 20F Installation Instructions Manual

• Requirements for supplementary mitigation that is related to specific
high-frequency emission limits are provided in
• PowerFlex 750-Series drives generate harmonic current emissions on the
AC supply system. When operated on a public low-voltage network it is
the responsibility of the installer or user to verify that applicable
requirements of the distribution network operator have been met.
Consultation with the network operator and Rockwell Automation can
be necessary.
ATTENTION: PowerFlex 750-Series drives produce DC current in the
protective earthing conductor that can 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. Where an RCD or
RCM is used for protection from direct or indirect contact, only an
RCD or RCM of Type B is allowed on the supply side of this product.
Installation Requirements Related to EN 61800-5-1 and the Low
Voltage Directive
This section lists installation requirements that are related to EN 61800-5-1

and the Low Voltage Directive.

Frame 1 Drives
Voltage classes up to 480V PowerFlex 750-Series Frame 1 drives can only be
used on a 'center grounded' supply system for altitudes up to and including
2000 m (6562 ft).
Frame 2 and Larger Drives
Voltage classes up to 690V, PowerFlex 750-Series Frame 2 and larger drives, are
compliant with the CE LV Directive when used on a 'corner-earthed' supply
system, and all other common supply systems, for altitudes up to and including
2000 m (6562 ft).
When used at altitudes above 2000 m (6562 ft) up to a maximum of 4800 m
(15,748 ft), PowerFlex 750-Series drives of voltage classes up to 480V cannot
be powered from a 'corner-earthed' supply system to maintain compliance with
the CE LV Directive. Altitude derating curves are provided in the PowerFlex
750-Series AC Drives Technical Data, publication 750-TD001.
