Safety concept

The converter and its components are subject to a comprehensive safety concept. When used
properly, the security concept guarantees safe installation, safe operation as well as safe
service and maintenance.
The safety concept encompasses safety components and functions to protect the device and
operators. The converter is also equipped with monitoring functions to protect external
components.
The converter operates safely when the interlock and protection systems are functioning
properly. Nevertheless, there are areas on the converter that are hazardous for personnel and
that cause material damage if the safety information of all the instructions and the labels on
the converter are not strictly observed.
