11.1Safety information for maintenance and repairs
DANGER
Risk of death, serious personal injury and/or material damage if maintenance and repair work is carried out by inexperienced personnel.
Make sure that maintenance personnel possess the knowledge, ability, and experience required to carry out their work safely.
All repairs to the motor must be carried out at one of the Siemens service centers. For addresses of Siemens service centers, see:

DANGER
Risk of death, serious personal injury and/or material damage if work is carried out when the machine is switched on. Before carrying out work in the vicinity of rotating parts, switch off the machine (disconnect it from the power supply).
Before carrying out work in the vicinity of rotating parts, disconnect the machine from the power supply to prevent accidental rotation.
DANGER
If work is carried out on the motor immediately after it has been in operation, there is a risk of burns if you come into contact with hot surfaces. The cooling water temperature can also increase after the motor has already been switched off.
To cool the motor down to the level of the inlet temperature TVORL, the cooler must remain in operation for at least 30 minutes after the motor has been switched off. If the cooler is switched off, however, it takes significantly longer for the motor to cool down. This depends to a large extent on the installation situation.
