Safety notes
Residual risks
The control and drive components of a power drive system (PDS) are approved for industrial
and commercial use in industrial supply networks. Their use in public supply networks
requires a different configuration and/or additional measures.
These components may only be operated in closed housings or in higher-level control
cabinets with protective covers that are closed, and when all of the protective devices are
used.
When carrying out a risk assessment of a machine in accordance with the EU Machinery
Directive, the machine manufacturer must consider the following residual risks associated
with the control and drive components of a PDS.
1. Unintentional movements of driven machine components during commissioning,
2. Exceptionally high temperatures as well as emissions of noise, particles, or gas caused
3. Hazardous shock voltages caused by, for example:
4. Electrical, magnetic and electromagnetic fields generated in operation that can pose a
5. Release of environmental pollutants or emissions as a result of improper operation of the
8
operation, maintenance, and repairs caused by, for example:
– Hardware defects and/or software errors in the sensors, controllers, actuators, and
connection technology
– Response times of the controller and drive
– Operating and/or ambient conditions not within the scope of the specification
– Condensation / conductive contamination
– Parameterization, programming, cabling, and installation errors
– Use of radio devices / cellular phones in the immediate vicinity of the controller
– External influences / damages
by, for example:
– Component malfunctions
– Software errors
– Operating and/or ambient conditions not within the scope of the specification
– External influences / damages
– Component malfunctions
– Influence of electrostatic charging
– Induction of voltages in moving motors
– Operating and/or ambient conditions not within the scope of the specification
– Condensation / conductive contamination
– External influences / damages
risk to people with a pacemaker, implants or metal replacement joints, etc. if they are too
close.
system and/or failure to dispose of components safely and correctly.
