Power Drive Systems
The control and drive components of a power drive system (PDS) are approved for industrial
and commercial use in industrial line supplies. Their use in public line supplies (public grids)
requires a different configuration and/or additional measures.
These components may only be operated in closed housings or in higher-level control
cabinets and when all of the protective devices and protective covers are used.
These components may only be handled by qualified and trained technical personnel who
are knowledgeable and observe all of the safety information and instructions on the
components and in the associated technical user documentation.
When carrying out a risk assessment of the machine in accordance with the EC Machinery
Directive, the machine manufacturer must consider the following residual risks associated
with the control and drive components of a Power Drive System.
1. Unintentional movements of driven machine components during commissioning,
2. Exceptional temperatures as well as emissions of light, noise, particles, or gas caused by,
3. Hazardous touch voltages, e.g. as a result of:
4. Electrical, magnetic, and electromagnetic fields that can pose a risk to people with a
5. Emission of pollutants if components or packaging are not disposed of properly.
For more information about residual risks, refer to the relevant chapters in the technical user
documentation.
