7.2 Performing a trial run
WARNING
Water cooling: risk of burning from hot steam
If the cooling water supply fails, the motor will overheat. If cooling water runs into the hot
motor, hot steam suddenly forms, which escapes under high pressure. The cooling water
system can burst. This can result in death, serious injury, or material damage.
Do not connect the cooling water supply until the motor has cooled down.
WARNING
With forced ventilation: risk of suction
There is a risk of suction at the air inlet (e.g. hair, ties, loose objects, etc.).
Suitable protection measures must be implemented by the operator
(remove ties, wear hair nets, keep suction area free, etc.).
WARNING
Danger from rotating rotor
Implement shock-hazard protection measures for output elements. Take suitable measures
to ensure that feather keys (if used) cannot fall out.
