Danger!
Risk of burns due to hot surfaces!
Touching hot surfaces (e.g. motor and gearbox housings, as well as connected components), can lead
to very severe burns due to the very high temperature of these parts.
•
Do not remain in a dangerous area during operation and secure it from access by unauthorized
persons.
•
Never touch the motor or gearbox housing as well as adjacent surfaces during nominal load
operation.
•
Be aware of hot surfaces also during downtime.
•
Allow motor and gearbox to cool sufficiently before working on it. Because even after shutting
down, there is still a risk of burning for a prolonged period of time.
•
Always operate the motor or gearbox with all safety devices. You should also do this during
short-term testing and trial operations!
5.2.2 Noise emissions
Take into account the health of personnel in proximity to the machine.
Warning!
Hearing damage due to noise levels.
During operation, the motor can exceed the permissible workplace noise level and also cause hearing
damage.
•
Implement suitable noise reduction measures (e.g. housings, covers or other sound-insulating
measures).
•
Take into account applicable industrial safety regulations.
5.3 Shaft end and bearing
The motor shaft is supported on both sides with grease-lubricated grooved ball bearings. Protect the motor from
damage due to excessive radial and axial forces!
Under all circumstances, avoid the following loads on the front shaft end or the rear motor housing cover:
•
Excessive pressure
•
Impacts
•
Hammer blows
Warning!
Damage due to excessive axial forces!
The bearings can be damaged by excessive axial forces (e.g. by impacting or pressing) on the shaft.
•
Do not hit the motor or output shaft with a hammer. The impact of a hammer certainly exceeds
the permissible values.
•
In addition, avoid impact and excessive pressure on the motor and output shaft.
Overdetermined bearing
Avoid an overdetermined bearing when attaching drive elements onto the output shaft! The necessarily occurring
tolerances cause additional forces on the output shaft bearing. This can damage or significantly reduce the service
life of the bearing!
Lifting and transporting
The weight of attachment elements (gear wheels, pulleys, couplings, etc.) can have a harmful effect on the bear-
ing during lifting and transportation from the motor. Take into account these radial and axial loads during these
operations!
