Hot surfaces
Electric machines have hot surfaces. Do not touch these surfaces. They
could cause burns.
• Allow the machine to cool before starting work on the machine.
• Only remove the covers using the methods described by these operating
instructions.
Danger of explosion.
If the anti-condensation heating is switched on directly after the motor
is switched off, the temperature class or the maximum surface temperature
of the motor can be exceeded.
In an explosive atmosphere, there is a high risk of an explosion. This
can result in death, serious injury or material damage.
Do not switch on the anti-condensation heating for at least one hour
after the motor has been switched.
Risk of explosion due to excessive bearing temperature.
The surface temperature cannot be maintained within the maximum
permissible limits if the bearings become too hot. The dust can ignite,
resulting in an explosion. This can result in death, serious injury or material
damage.
• Always check the bearing temperature.
• In addition to the current-dependent overload protection device
located in the three phases of the connecting cable, we recommend that you
also monitor the temperature rise in the motor with the aid of the
temperature sensors integrated built into the stator winding.
