Store the rotor locking device
Be sure to store the rotor locking device. It must be remounted for possible disassembly and
transport.
Details about the alignment accuracy can be found in the Section "Information about the
machine dimension drawing".
5.4.4 Recommended alignment accuracy
The alignment accuracy required depends essentially on the configuration of the overall
machine train. Observe the required alignment accuracy of the coupling manufacturer in all
cases when aligning the machine.

To avoid stressing the motor feet, the overall flatness of the installation surfaces must satisfy
the values in the following table:
Table 5- 3 Overall flatness of the installation surfaces
Frame size Overall flatness of the installation surfaces
≤ 080 0.1 mm
090 - 355 0.2 mm
≥ 400 0.3 mm
If shims are necessary for height adjustment and to avoid stresses, make them out of
adequately sized pieces of flat rolled strip. Complete balancing of the rotor together with the
transmission element may be found necessary.
