CAUTION
Risk of injury due to Incorrect installation or removal
If the required touch protection measures for drive output elements are not observed this can
result in physical injury and material damage.
● The general touch protection measures for drive output elements must be observed.
● Drive output elements may only be pushed on or pulled off with the correct equipment.
● The feather keys are only locked against falling out during shipping. If you commission a
machine without a drive output element, the feather keys must be secured to prevent them
from being thrown out.
Shaft extensions with feather key
● If the output element is shorter than the feather key for balancing type "H": Cut off the section
of the feather key that protrudes from the shaft contour and output element. Alternatively,
ensure that the weights are compensated to achieve the appropriate balance quality.
● If the output element is pulled on up to the shaft shoulder: When balancing the coupling, take
into account that the feather key does not take up all of the coupling slot.
● The following applies for all two-pole machines and four-pole machines with a frequency
≥60 Hz:
– The feather key must be shortened if the coupling hub is shorter than the feather key.
– The center of gravity of the coupling half is within the length of the shaft extension.
– The coupling used is prepared for system balancing.
The number of poles of the machine is specified on the rating plate (in the designation of the
motor type).
