Furthermore, the device and the associated accessories may only be installed and started up by
qualified electricians. Electricians are persons who, because of their technical training and experience,
have sufficient knowledge with regard to
•
Switching on, switching off, isolating, grounding and marking power circuits and devices,
•
Proper maintenance and use of protective devices in accordance with defined safety standards.

3. Correct purpose of use – general
Variable Frequency Drives are devices for industrial and commercial systems that are used to operate
three-phase asynchronous motors with squirrel-cage rotors and permanent-magnet synchronous
motors (PMSM). These motors must be suitable for operation with variable frequency drives. Other
loads must not be connected to the devices.
The devices are components intended for installation in electrical systems or machines.
Please refer to the nameplate and in the documentation for technical data and information about
connection conditions, which must be complied with.
The devices may only be used for safety functions which are described and explicitly approved.
CE-marked devices meet the requirements of the Low-Voltage Directive 2014/35/EU. The
aforementioned harmonized standards for the devices are used in the declaration of conformity.
a. Supplement: Intended use within the European Union
When installed in machines, startup of the devices (i.e. commencement of intended operation)
is prohibited until it has been ensured that the machine meets the provisions of EC Directive
2006/42/EC (Machinery Directive). EN 60204-1 must also be complied with.
Commissioning (i.e. commencement of intended operation) is only permitted if the EMC
directive (2014/30/EU) has been complied with.
b. Supplement: Intended use outside the European Union
Adhere to local and national regulations regarding the installation and commissioning of the
device (see also "a) Supplement: Intended use within the European Union").

Transport, storage
Follow the instructions in the manual regarding transport, storage and correct handling.
Comply with the permissible mechanical and climatic ambient conditions (see Technical Data in the
device manual).
If necessary, use suitable and adequately dimensioned means of transport (e.g. lifting gear, cable
guides).

Installation and assembly
Installation and cooling of the device must be carried out according to regulations in the corresponding
documentation. Comply with the permissible mechanical and climatic ambient conditions (see
Technical Data in the device manual).
Protect the device against inadmissible loads. In particular, prevent component deformation and/or
modification of insulation distances. Avoid touching electronic components and contacts.
The device and its optional modules contain electrostatically sensitive components which can be
easily damaged by incorrect handling. Electrical components must not be mechanically damaged or
destroyed.
