5.3.2
Selecting bolts
● Use fixing bolts with the appropriate property class to ensure that the machine is securely
fastened and torque can be adequately transmitted.
● When selecting the bolts and the design of the foundation, take into account the maximum
forces occurring in the case of a fault such as short circuit or line system transfer operations
in phase opposition, etc. Values for the foundation forces can be found in the "Technical
Data and Drawings" section.

5.3.3
Preconditions for smooth, vibration-free operation
Preconditions for smooth, vibration-free operation:
● Stable foundation design
● Precise alignment of the machine
● Correct balancing of parts to be fitted to the shaft end.
● Maintaining the vibration velocity according to ISO 10816‑3
5.3.4
Aligning and attaching the machine to the driven machine
1. Refer to any instructions for aligning the driven machine and those of the coupling
manufacturer.
2. Align the machines with coupling output to the driven machine in such a manner that the
center lines of the shafts are parallel with no offset. This ensures that no additional forces
affect their bearings during operation.
3. For the vertical positioning (x→0) place thin shims under the machine feet. The number of
shims should be kept as low as possible, i.e. stack as few as possible. This also prevents
the machine being subjected to any stress/distortion. Use the existing tapped holes for the
forcing-off bolts to raise the machine.
4. When positioning the machine, ensure that a uniform axial gap (y→0) is maintained around
the coupling.
