The circuit diagram is a system scheme for assignment and order of the safety chain, without
error messages and installation arrangement (whether inside or outside the Ex zone).
When devices are installed, the safety regulations of the corresponding installation zone must be followed.
The rating plate information and operating manual from the manufacturer of the components
to be used must always be observed.
