28 Operating Instructions, 07/2020, A5E50009094A/RS-AL
If the gearbox is fastened to a concrete foundation, use foundation blocks for the appropriate
recesses.
Align and grout the slide rails into the foundation.
Align the gearbox carefully with the units on the input and output side. Take into account the
elastic deformation due to operating forces.
Prevent displacement from external forces due to lateral impacts.
Use stud bolts or headless screws of strength class 8.8 or higher for the mounting foot.
Observe the tightening torque.
