8.1 Safety instructions for operation
Observe Chapter, "Safety instructions" when carrying out any work at the converter.
DANGER
Operation with the doors open
High voltages are present in the drive and its components during operation and also after it
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.
● Never operate the drive with doors open.
WARNING
Faults
Operating the converter when a fault has arisen can result in death, serious injury or
substantial material damage.
● Observe the fault and alarm messages.
● Eliminate the source of the fault. Only put the converter back into operation once this is
resolved. 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".
WARNING
Unpermitted operation 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.
If a ground fault is experienced during drive operation, the drive must be switched off
immediately. Then identify and eliminate the source of the ground fault.
The plant operating company is responsible for the consequences, if the drive is still operated
after a ground fault has been detected. Carry out a risk analysis.
