Motor without output element
The feather key can fall out
The featherkeys are only secured during transport to prevent them from falling out. If a
motor is not equipped with an output element, the feather key may fall out during operation.
Death or serious injury can result.
At the shaft extension, secure the fitted key without output element so that it cannot be
flung out and for balance type "H" shorten it by approximately half.

Vibration load
The on-site system vibration characteristics depend on factors such as the output elements,
assembly conditions, alignment, installation, and external vibrations and can increase the
level of vibration on the motor.
Under certain circumstances, the rotor may have to be balanced completely with the output
element.
To ensure problem-free operation and a long service life, the vibration values specified to
ISO 10816 must not be exceeded at the defined measuring points on the motor.
