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
Overall flatness of the installation surfaces
090 - 355 0.2 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.

Balance quality
The rotor is dynamically balanced. For shaft ends with feather keys, the balancing type is
specified using the following coding on the rating plate:
● "H" means balancing with a half feather key
● "F" means balancing with a whole feather key
● "N" means balancing without a featherkey.
