Safety instructions for operation
When carrying out any work, carefully observe the information provided in Chapter "Safety
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
information on alarms and faults in the section "Indicating and rectifying faults."
● If it is not possible to correct a fault, inform the manufacturer's service personnel
immediately. For additional information, see Chapter "Service & support".
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 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
eliminate the source of the ground fault.
● The company operating the plant or system is responsible for the consequences when the
device is still operated after a ground fault has been identified. Carry out a risk analysis.
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
times.
Damage caused by incorrect parameter assignment
Malfunctions can occur if you change parameters.
● Do not change the parameters, e.g. for the motor circuit-breaker.
