7.1  Measures before 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 both moving and live parts have been implemented. 
•  Screwed-in lifting eyes are removed after installation or secured to prevent them from 
becoming loose.
