Commissioning
7.1 Prior to commissioning
Electrical connection
● The grounding and equipotential bonding connections have been made correctly.
● The machine is connected so that it rotates in the direction specified.
● Appropriately configured control and speed monitoring functions ensure that the motor
● The minimum insulation resistance values are within tolerance.
● Minimum air clearances have been maintained.
● Any supplementary motor monitoring devices and equipment have been correctly
● The values for "Alarm" and "Shut down" at the monitoring equipment are set to the values
● All brakes and backstops are operating correctly.
Switching overvoltages
When high-voltage machines with starting current I
after they have been blocked, then in individual cases inadmissibly high switching overvoltages
for the stator winding insulation can occur through multiple restrikes.
The peak voltages which arise as a result can damage the winding insulation.
● If you are using vacuum circuit breakers and vacuum contactors, use an appropriate surge
● An additional RC arrester (resistor and capacitor connected in series) makes sense at

Converter operation
● If the design of the motor requires connection to a particular converter type, the rating plate
● The converter is correctly parameterized. The parameterization data is specified on the
● Any supplementary motor monitoring devices and equipment have been correctly
● In continuous operation, the motor cannot exceed the specified upper speed limit n
● The bearing insulation should be implemented as shown on the plates.
