Chapter 3 Prepare for Installation
Consultation with the network operator and Rockwell Automation can
be necessary.
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
• PowerFlex 755TS 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
• PowerFlex 755TS products are compliant with the CE LVD when used on
a ‘corner-earthed’ supply system and all other common grounded 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 755TS products cannot be powered from a
‘corner-earthed’ supply system to maintain compliance with the CE LVD.
Altitude derating curves are provided in the PowerFlex 755TS Products
with TotalFORCE Control Technical Data, publication 750-TD104
.
• Drives that are provided in the IP54, NEMA/UL Type 12 enclosure are
compliant with the CE LVD when installed in pollution degree 1…4
environments where no gaseous contaminants are present. All other
enclosure types must be installed in a pollution degree 1 or 2
environment to be compliant with the CE LVD. Characteristics of the
different pollution degree ratings are provided in the PowerFlex 755TS
Products with TotalFORCE Control Technical Data, publication
750-TD104
.
• PowerFlex 755TS products produce leakage current in the protective
earthing conductor that exceeds 3.5 mA AC and/or 10 mA DC. The
minimum size protective earthing conductor must be at least 2.5 mm
2
Cu as part of a multi-conductor power cable, or fixed connection with at
least 10 mm
2
Cu or 16 mm
2
Al. The conductor must also comply with local
regulations as already stated.
ATTENTION: PowerFlex 755TS products produce DC current in the
protective earthing conductor which 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 in case of direct or indirect contact, only
an RCD or RCM of Type B is allowed on the supply side of this product.
