Drive technology for AC and DC

Basic information on standards and guidelines (EC/DC)Basic information on standards and guidelines for electrical smallpowermotors and drive systems operated with a DC voltage ofmax. 75 VDC (nominal voltage):The series described in this catalogue, the Variodrive, Variodrive Compact,ECI, ECI Compact and BCI, are direct current motors in an electronicallycommutated or brush-commutated design, all of which are designed andspecified for a nominal voltage of max. 75 VDC. Thus the supply voltageof these drives is within the range of safety extra-low voltage (SELV). Onthis basis, ebm-papst would like to provide some information intended tohelp you understand the classification of the motors from the relevant ECDirectives and the resulting consequences.The CE label:In or to ensure a uniform safety level in the European internal market, theEuropean commission has implemented a new approach for technicalharmonisation. This has been welcomed by all relevant parties and is visiblein many products as a CE label giving proof of agreement with theharmonised provisions.What does CE actually mean?Why don’t all products bear the CE label?CE is the abbreviation for “Communauté Européenne”. The harmonisedstatutory provisions are framework directive and belong to the so-calledNew Approach. These framework directive define the basic requirements,putting in circulation and operation as well as the applicable conformityassessment process. The manufacturer of a product must now decidewhich skeleton guideline applies to which product. For electrical smallpoweredmotors the following framework directive can be applied:1) Mechanical engineering Directive 2006/42/EC2) Electrical engineering Low Voltage Legislation:Low Voltage Directive (LVD) 2006/95/ECBased on these directives, ebm-papst St. GeorgenGmbH & Co. KG does not mark the drive systemsdescribed in these installation instructions with the"CE" mark and does not issue an EC Declaration ofConformity. The reason for this is consideration ofthe relevant EC Directives and the definitions of theterms used, >Electric motor< and >Drive system
