7.1 Measures before start-up
● Lubricate the bearings, depending on the version. Ensure that machines with roller
bearings, which have been stored for longer than 24 months, are relubricated.
Also observe the notes in Chapter Preparation for use (Page 15).
● Ensure that any optional supplementary machine monitoring equipment has been
connected correctly and is functioning as it should.
● For versions with bearing thermometers, check the bearing temperatures when the
machine starts to run for the first time. Set the values for alarm and shutdown at the
monitoring device. Also observe the notes in Chapter Setting values for monitoring the
bearing temperature.
● Corresponding to the control and speed monitoring functions implemented, ensure that
the machine cannot exceed the permissible speeds specified on the rating plate.
● Ensure the correct setting conditions of the drive output elements depending on the type
(e.g. alignment and balancing of couplings, belt forces in the case of a belt drive, tooth
forces and tooth flank backlash/play in the case of gear wheel output, radial and axial
clearance in the case of coupled shafts).
● Comply with the minimum insulation resistances and minimum air clearances.
● Ensure correct grounding and potential bonding connection of the protective conductor.
● Tighten all mounting bolts, connection elements and electrical connections to the
specified torques.
● Remove any lifting eyes that were screwed after installation – or secure them to prevent
them becoming loose.
● Rotate the rotor to ensure that it does not touch the stator.
● Implement all touch protection measures for both moving and live parts.
● Ensure that free shaft extensions cannot be touched, e.g. by attaching covers.
● Secure any featherkeys so that they cannot be flung out.
● Ensure that the optional external fan is ready for operation and connected so that it
rotates in the specified direction.
● Ensure that the cooling airflow is not obstructed or diminished in any way.
● If an optional brake is being used, ensure that it is functioning perfectly.
● Comply with the specified mechanical limit speed n
If the design of the machine requires the converter to be assigned in a particular way, the
relevant information will be provided on the rating plate or an additional label.
Note
It may be necessary to perform additional checks and tests in accordance with the specific
situation on site.
