General
Some parts of Lenze controllers (frequency inverters, servo inverters, DC controllers) can be live,
moving and rotating. Some surfaces can be hot.
Non-authorized removal of the required cover, inappropriate use, and incorrect installation or operation
creates the risk of severe injury to personnel or damage to equipment.
All operations concerning transport, installation, and commissioning as well as maintenance must
be carried out by qualified, skilled personnel (IEC 364 and CENELEC HD 384 or DIN VDE 0100 and
IEC report 664 or DIN VDE0110 and national regulations for the prevention of accidents must be
observed).
According to this basic safety information, qualified skilled personnel are persons who are familiar with
the installation, assembly, commissioning, and operation of the product and who have the qualifications
necessary for their occupation.
Application as directed
Drive controllers are components which are designed for installation in electrical systems or machinery.
They are not to be used as appliances. They are intended exclusively for professional and commercial
purposes according to EN 61000-3-2. The documentation includes information on compliance with
the EN 61000-3-2.
When installing the drive controllers in machines, commissioning (i.e. the starting of operation as
directed) is prohibited until it is proven that the machine complies with the regulations of the EC Directive
98/37/EC (Machinery Directive); EN 60204 must be observed.
Commissioning (i.e. starting of operation as directed) is only allowed when there is compliance with
the EMC Directive (89/336/EEC).
The drive controllers meet the requirements of the Low Voltage Directive 73/23/EEC. The harmonised
standards of the series EN 50178/DIN VDE 0160 apply to the controllers.
Note: The availability of controllers is restricted according to EN 61800-3.These products can cause
radio interference in residential areas. In this case, special measures can be necessary.
Installation
Ensure proper handling and avoid excessive mechanical stress. Do not bend any components and
do not change any insulation distances during transport or handling. Do not touch any electronic
components and contacts.
Controllers contain electrostatically sensitive components, which can easily be damaged by inappropriate
handling. Do not damage or destroy any electrical components since this might endanger your
health!
Electrical connection
When working on live drive controllers, applicable national regulations for the prevention of accidents
(e.g. VBG 4) must be observed.
The electrical installation must be carried out according to the appropriate regulations (e.g. cable cross-
sections, fuses, PE connection). Additional information can be obtained from the documentation.
The documentation contains information about installation in compliance with EMC (shielding, grounding,
filters and cables). These notes must also be observed for CE-marked controllers.
The manufacturer of the system or machine is responsible for compliance with the required limit values
demanded by EMC legislation.
