Page 10: Balancing, Drive Elements And Vibration
Balancing, drive elements and vibration The shaft and bearing must not be exposed to knocks. No axial forces are permitted when mounting or dismounting the output elements. The generally required measures to prevent contact with the output elements must be observed. -
Page 11: Mounting
Vibration: The site vibration response of the system, which is determined by the output elements, the mounting conditions, the alignment, the installation and the effects of external vibrations, may cause the vibration values at the motor to increase. In the interest of reliable motor operation and a long bearing service life, the permitted vibration values in accordance with EN 60034-14 should not be exceeded. -
Page 12: Vibrations And Resistance To Vibrations
When using standard solvents such as Acetone or benzine, the shaft sealing ring must not be moistened! • the motor is designed for the ambient conditions and environmental influences on site (see Section 2.4). • the compartment in the machine is suitable for the cooling method employed by the electric motor (see Section 2.6). - Page 13 The specified maximum radial and axial vibration values must be adhered to at the same time. They apply to substructures which can be described as elastic. An elastic substructure is present if the lowest natural frequency of the overall system (machine and base) in the measuring direction is at least 25% below the essential excitation frequency.

Page 19: Maintenance
If equipped with the optional shaft sealing ring, this must be checked regularly to ensure that it is functioning correctly (leaks). Note on thrust-bearing motors: An inspection hole for leak oil from the thrust-bearing housing is located on the bottom of the A-side bearing end plate near the feet (see Appendix 3 – Fig. 1). If oil exits here, the shaft sealing rings of both sealing points must be replaced. -
Page 20: Re-Lubrication (Optional)
5.3 Re-lubrication (optional) Attention: Re-lubrication only with grease outlet open. Prior to re-lubrication it is imperative that the covers be removed from the grease outlet opening. Re-grease bearing with re-lubrication device only when the motor is running. After re-lubrication, 2 - 4 hours of motor operation is necessary (the old bearing grease is ejected from the grease outlet opening by the rotation of the bearing), the cover is then to be refitted to the grease outlet opening. -

Leak test acc. to EN 50178: The cooling system is to be checked for leaks before commissioning by pressure testing with coolant (water). The test pressure must be twice the operating pressure (minimum test pressure 1 bar). The coolant used does not have to be brought to operating temperature for this purpose. -
