any effect on the safety of the system. However, in the safety-critical area, only controllers
and circuits that comply with the relevant regulations, may be used.
Important note
Even if an extremely high level of conceptual safety has been achieved in the design of an
electronic controller - e.g. through implementation of a multi-channel design - strict
adherence to all instructions in the operator's guide is mandatory, as incorrect handling could
invalidate measures taken to prevent hazardous faults or create additional potential hazards.
Electrical, magnetic and electromagnetic fields (EMF) that occur during operation can pose
a danger to persons who are present in the direct vicinity of the product - especially
persons with pacemakers, implants, or similar devices.
The relevant directives and standards must be observed by the machine/plant operators
and persons present in the vicinity of the product. These are, for example, EMF Directive
2004/40/EEC and standards EN 12198-1 to -3 applying to the European Economic Area
(EEA) and in Germany the accident prevention regulation BGV 11 and the associated rule
BGR 11 "Electromagnetic fields" from the German employer's liability accident insurance
association.
These state that a hazard analysis must be drawn up for every workplace, from which
measures for reducing dangers and their impact on persons are derived and applied, and
exposure and danger zones are defined and observed.
The safety information in the Storage, Transport, Installation, Commissioning, Operation,
Maintenance, Disassembly and Disposal sections must also be taken into account.
