Safety instructions

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
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 heating devices, are also disconnected.
Danger of burns
Some parts of the frame of electrical motors can reach temperatures in excess of 100°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.
Safety regulations
Before starting maintenance work, always observe the five safety rules.
1. Disconnect the system.
2. Protect against reconnection.
3. Make sure that the equipment is de-energized and in a no-voltage condition.
4. Ground and short-circuit.
5. Cover or enclose adjacent components that are still live.
