3.2
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.
3.2.1
Safety components and functions
The drive has the following safety components and functions to protect personnel:
● The make-proof grounding switch for grounding the voltage DC link.
● The electromechanical door interlock system prevents access to the power unit while the
drive is in operation. The doors cannot be opened until the grounding switch has been
closed. The door for the control section, however, can be opened for monitoring purposes
even during operation.
