- Take note of and observe the information on the rating plate and warning and informative
notices on the motor.
- Observe the permitted transverse and axial forces (see project planning instructions).
Axial forces are not permitted on motors with an integrated brake.
- Check for compliance with the conditions (e.g. temperature, site altitude) at the assembly
site (see Section 3.2).
- It is forbidden to use them in areas at risk of explosion.
- Remove all anti-corrosion agents from the shaft end (use commercially available
solvent).
- Ensure that waste heat is adequately dissipated.
It is recommended to maintain a clearance of 100 mm from adjacent parts on at least
three sides.
- Tighten the flanges equally, avoid distortions when tightening the fixing screws. Use
hexagon socket head cap screws, strength class at least 8.8.
- In the case of a vertical installation with the shaft end at the top, ensure that no fluid
penetrates into the upper bearing.
- Lifting eye-bolts which have been screwed in may be removed after the motor has been
installed.
- Turn the output elements by hand. If grinding noises occur, eliminate the cause or
contact the manufacturer.
- Please observe the tightening torques to be applied to the motor flange fastening screws:

Vibrations, balancing
Motors with a keyway are balanced by the manufacturer with a half feather key.
The site vibration response of the system is determined by the output elements, the
mounting conditions, the alignment, the installation and the effects of external vibrations.
This may cause a modification of the motor vibration values.
