Installation Requirements Related to EN 61800-5-1 and the Low Voltage Directive
- Voltage classes up to 690VPowerFlex®drive 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®drive products of voltage classes up to 480V cannot be powered from a ‘corner-earthed’ supply system to maintain compliance with the CE LVD. Altitude derating curves are provided in 750-TD100.
- Drives that are provided in the IP54, 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 750-TD100.
- PowerFlex®drive products produce leakage current in the protective earthing conductor that exceeds 3.5 mA AC and/or 10 mA DC. The minimum size of the protective earthing (grounding) conductor that is used in the application must comply with local safety regulations for high-protective earthing conductor current equipment.
ATTENTION:
Risk of equipment damage exists.
PowerFlex drive 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 if jumpers aren’t properly disconnected on the supply side of this product.
