7.2 Checks to be carried out prior to commissioning
The following list of checks to be performed prior to commissioning does not claim to be
complete. It may be necessary to perform further checks and tests in accordance with the
specific situation on-site.
Once the system has been correctly installed, you should check the following prior to
commissioning:
● The machine is undamaged.
● The machine has been properly installed and aligned.
● The output transmission elements are set correctly for their type,
e.g. alignment and balancing of couplings, belt forces in the case of a belt drive, tooth forces
and tooth-flank backlash in the case of geared output, radial and axial clearance in the case
of coupled shafts.
● All fixing screws, connection elements, and electrical connections have been tightened to
the specified tightening torques.
● The operating conditions match the data provided in accordance with the technical
documentation, such as degree of protection, ambient temperature, etc..
● Moving parts, for example the coupling, move freely.
● All touch protection measures for moving and live parts have been taken.
● Screwed-in lifting eyes are removed after installation or secured to prevent them from
becoming loose.
● For test operation or when commissioning without output element, carefully secure the
feather key using a suitable security element. When doing this, take into account the
balancing type of the motor.
Second shaft extension
If the second shaft extension is not used:
● Carefully secure the feather key to prevent it from being thrown out, and for balancing type
"H" (standard type), ensure its weight is reduced to approximately 60 % of the original value.
● Using covers, carefully secure the unused shaft extension so that it cannot be touched.
Electrical connection
● Carefully check the grounding and potential bonding connections.
● Connect the machine corresponding to the specified direction of rotation.
● Using the appropriate open-loop control and speed monitoring functions, carefully ensure
that no higher speeds can be achieved than are permitted and specified in the technical
data. For this purpose, compare the data on the rating plate or, if necessary, the system-
specific documentation.
● Comply with the minimum insulation resistances.
● Comply with the minimum air clearances.
● Correctly connect possibly available machine monitoring devices and equipment - and
carefully ensure that they are functioning correctly.
