WARNING
Do not remove covers when the motor is running
Rotating or live parts are dangerous. Death, serious injury, or material damage can result if
the required covers are removed.
All covers that prevent personnel from coming into contact with active or rotating parts,
ensure compliance with the required degree of protection, or ensure proper air guidance
and, in turn, effective cooling must not be opened/removed during operation.
WARNING
Faults in operation
Deviations from normal operation (e.g. increased power consumption, temperature, or
vibration levels, unusual noises or smells, tripping of monitoring equipment, etc.) indicate
that the machine is not functioning properly. This can cause faults that can result in
eventual or immediate death, severe personal injury, or material damage.
Immediately inform the maintenance personnel. If in doubt, shut down the motor
immediately, taking into account the plant-specific safety regulations.
CAUTION
Danger of burns
The temperature of certain parts of the motor can exceed 100 °C. Physical contact can cause
serious burns.
Check the temperature of the parts before touching them and take appropriate protective
measures if necessary.
