Safety information
1.3 Components that can be destroyed by electrostatic discharge (ESD)
Residual risks of power drive systems
When carrying out a risk assessment of the machine/plant in accordance with the EU
Machinery Directive, the machine manufacturer/plant operator must consider the following
residual risks associated with the control and drive components of a power drive system
(PDS).
1. Unintentional movements of driven machine components during commissioning,
operation, maintenance, and repairs caused by, for example:
2. Exceptional temperatures as well as emissions of light, noise, particles, or gas caused by,
for example:
3. Hazardous shock voltages caused by, for example:
4. Electrical, magnetic, and electromagnetic fields that can pose a risk to people with a
pacemaker and/or implants if they are too close.
5. Emission of pollutants if components or packaging are not disposed of properly.
An assessment of the residual risks of Power Drive System components (see points 1 to 5
above) established that these risks do not exceed the specified limit values.
For more information about residual risks of the Power Drive System components, see the
relevant chapters in the technical user documentation.
