5.1 Safety instructions
WARNING
Hot surfaces
Electrical machines have hot surfaces.
Fatal or severe injuries and substantial material damage can occur if the
required covers are removed or if the machines are not handled,
operated, or maintained properly.
●
Allow the machine to cool down before starting any work on it.
● Only remove covers in compliance with the applicable regulations.
● Operate the machines properly.
It must be ensured that parts (cables etc.) do not come into contact with
the machine enclosure.
NOTICE
Before start-up, please check that
●
the customer has set the correct direction of rotation of the machine - e.g. by
decoupling from the driven machine - by taking appropriate measures!
● there are no temperature-sensitive parts (cables etc.), which are in contact with
the machine enclosure.
● condensation drain holes are always located at the lowest point of the motor!
Note
Please note the technical data on the rating plates on the machine enclosure.
5.2 Electromagnetic compatibility
Note
If the torque levels are very unequal (e.g. when a reciprocating compressor is being
driven), a non-sinusoidal machine current will be induced whose harmonics can have
an impermissible effect on the supply system and cause impermissible interference
emissions as a result.
