Notes for Machine Manufacturers
The SIMATIC programmable controller is not a machine in the sense of the
EC Directive on machines. Therefore, there is no declaration of conformity
for SIMATIC as regards the EC Directive 89/392/EEC on machines.
The EC Directive 89/392/EEC on machines controls machine requirements.
Here, a machine is understood to be the entire sum of devices or parts
involved (see also EN 292-1, paragraph 3.1).
SIMATIC is part of the electrical equipment for a machine and must
therefore be included in the procedure for checking conformity by the
machine manufacturer.
The EN 60204-1 standard (machine safety, general requirements for the
electrical equipment for machines) applies to the electrical equipment for
machines.
The following table should help you with the declaration of conformity and
shows which criteria apply to EN 60204-1 (as at June 1993) for SIMATIC.
