Safety 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 T
VORL
, 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.
