Warning!
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 stay in the danger zone during operation and secure it against 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. This is because there is still
a risk of burning for a prolonged period of time even after shutting down.
•
Always operate the motor or gearbox with all safety devices. Do this even during short testing
and trial operations!
6.2.2 Reversing operation
Warning!
Personal injury and damage to property due to shaft breakage!
The shaft key can become dislodged during heavy reverse operation. In extreme cases, this can cause
the shaft end to break, which can lead to severe damage!
•
It is therefore preferable to use a smooth shaft during heavy reversing operation.
6.2.3 Freely rotating motors
With freely rotating motors, remove any existing shaft keys (or mounting screws or other mounting elements) before
operation or implement measures to prevent their ejection. Any shaft protection sleeve present, such as used for
transport and storage, is not appropriate protection and must also be removed.
Warning!
Personal injury and damage to property due to ejected elements!
With freely rotating motors, an existing shaft key (or mounting screws or other mounting elements)
can be ejected and cause personal injury and damage to property.
•
Remove or secure shaft keys (or mounting screws or other assembly elements) before opera-
tion (even during short-term testing and trial operations!).
•
Any shaft protection sleeve present, such as used for transport and storage, is not appropriate
protection and must also be removed.
6.2.4 Holding brake
The motors can be equipped with an optional holding brake. It is only used to hold the motor shaft in place when
no power is applied to the motor.
The maximum motor torque far exceeds the holding torque of the brake.
