Safety instructions for operation

When carrying out any work, carefully observe the information provided in Chapter "Safety
instructions (Page 13)".
Danger due to high voltages
High voltages are present during operation and also after the device has been switched off.
When touched, these voltages can lead to death or severe injury.
● Ensure that no voltage is present when the doors of the power unit are open.
● Keep the doors closed when operational.
Danger if operated in spite of faults
Operation with an active fault can result in death, severe injury and significant material damage.
● Observe the fault and alarm messages.

signal. In the event of continued operation, serious aftereffects all the way to electric arcs are
possible. This can result in death, serious injury or material damage.
● Immediately switch off the device if a ground fault occurs during operation. Then identify and
● The company operating the plant or system is responsible for the consequences when the
Danger when the permissible short-circuit currents are exceeded
Serious follow-on faults are possible, if the specified short-circuit current values are exceeded.
