Safety instructions for operation
When carrying out any work, carefully observe the information provided in Chapter "Safety
instructions (Page 15)".
Electric shock caused by a high voltages
High voltages are present both 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.
● Always keep the doors closed in operation.
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.
● Eliminate the source of the fault. Only then commission the device. You can find further
● If it is not possible to correct a fault, inform the manufacturer's service personnel
Danger when operating with ground fault
The type and location of the fault cannot be established just from a ground fault error message.
For example, the glow discharge at the winding overhang of the machine may result in a fault
signal. In the event of continued operation, serious follow-on faults up 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.
This can result in death, serious injury or material damage.
● Observe the maximum permitted short-circuit currents and maximum specified short-circuit
