Safety Information For Iec 61800-5; External Safety Components; Protection And Monitoring Functions Of Internal Components - Siemens SINAMICS SL150 Operating Instructions Manual

Description
3.2 Safety concept
3.2.2

Safety information for IEC 61800-5

Insufficient grounding
High voltages can still be present even after shutdown. If live parts are touched, this can result
in death or severe injury.
A grounding switch is not installed. The system operator must, therefore, ensure that there is
sufficient grounding.
Ensure sufficient grounding during work on the power unit. Further information on grounding
can be found under "Safety information for maintenance and repairs".
3.2.3

External safety components

The safety concept of the converter is supplemented by the following external components:
● Circuit breaker
● Input-side transformer
3.2.4

Protection and monitoring functions of internal components

The internal components have the following protection and monitoring functions:
● Protection based on monitoring systems:
● Shutdown in the event of semiconductor failure
● Shutdown in the event of control component failure
● Internal protection functions for the control hardware
● Protection against communication failure between the closed-loop control and the power

DANGER
You can find more detailed information in the section "Circuit breaker (provided by the
customer)".
When an error is detected, the medium-voltage transformer limits the short-circuit current
and is configured in such a way that the maximum permissible short-circuit current (see the
technical data) is not exceeded.
