Setpoint values for monitoring the bearing temperature
Prior to commissioning
If the machine is equipped with bearing thermometers, set the temperature value for
disconnection on the monitoring equipment before the first machine run.

Measures for start-up
After installation or inspections, the following measures are recommended for normal start-up
of the machines:
• Start the machine without a load. To do this, close the circuit breaker and do not switch the
machine off prematurely. Switching the machine off again while it is starting up and still
running at slow speed should be kept to a bare minimum, for example for checking the
direction of rotation or for checking in general. Allow the machine to run to a standstill before
switching it back on again.
• Check mechanical operation for noise or vibration at the bearings or end shields.
• If the machine is not running smoothly or is emitting abnormal noises, switch it off, and
determine the cause of the fault as it runs down.
