General information
If the safety requirements from this documentation are met, then all connection variants listed in this documentation are generally permitted for safety-relevant applications. This means that you must ensure without fail that the DC 24 V safety inputs are activated by a safety controller or an external safety relay, so that an independent restart is not possible.
All the safety conditions stipulated in the chapters "Integrated safety technology", "Safety conditions", and "Connection variants" must be satisfied on a primary basis for the basic selection, installation, and application of the safety components such as safety relay, emergency stop switch, and the approved connection variants.
The wiring diagrams in chapter "Electrical installation" are block diagrams whose only purpose is to show the safety sub-function(s) with the relevant components. For reasons of clarity, circuit-related measures that always have to be implemented are not shown in the diagram. These measures are, e.g.:
- Ensuring the availability of touch guards.
- Handling overvoltages and undervoltages.
- Avoiding insulation faults.
- Detecting ground faults or short circuits in externally installed lines.
- Guaranteeing the required interference immunity against electromagnetic interference.
