Mounting information and instructions
The following mounting instructions must be carefully observed:
● For high-speed machines, we recommend that the complete unit is dynamically balanced
● Use suitable equipment when mounting drive elements. Use the thread at the shaft end.
● Do not apply any blows or axial pressure to the shaft end.
● Especially for high-speed motors with flange mounting, it is important that the mounting is
● With flange mounting, the vibration quality of the drive unit can be negatively affected if
● For 1PH4 motors, the screw hole cover plates for the foot fastening should be reattached

drive end is required to adhere to the vibration severity limit values.
after mounting the motor.
CAUTION
Liquid must be prevented from collecting in the flange, both in the vertical as well as
horizontal mounting positions. This would have a negative impact on the bearing and
bearing grease.
