Safety information
If you are unclear about anything, consult the manufacturer, specifying the motor type and
serial number, or arrange for the maintenance work to be carried out by one of the Siemens
Service Centers.
Risk of electric shock from touching live parts
For synchronous motors, hazardous voltages are present at the motor terminals when the
rotors are rotating.
Live electrical parts are dangerous. Touching these parts will result in an electric shock,
which in turn causes death or serious injury.
Before starting work on the machines, make sure that the plant or system has been
disconnected in a manner that is compliant with the appropriate specifications and
regulations. In addition to the main currents, make sure that supplementary and auxiliary
circuits, particularly in heating devices, are also disconnected.
Note all the information provided in "Safety information and application information" in these
operating instructions and ensure that only persons who have the necessary know-how are
entrusted to carry out work on power installations.
Danger of burns
Some parts of the enclosure of electrical machines can reach temperatures in excess
of 65 °C.
Touching components when the machine is in operation can cause severe burns.
Do not touch frame parts while the machine is in operation or immediately after machine
operation. Allow frame parts to cool off before starting any work.
