Prolonged storage periods reduce the useful life of the bearing grease. If stored for
more than 12 months, the condition of the grease must be checked. If the grease is

The shafts must be turned once a year to prevent marks as a result of them resting in
the same position for a long time. The rolling-contact bearings should be renewed if

Safety instructions

CAUTION
The housing parts of electrical machines can become very hot!
CAUTION
Before commissioning can be carried out, the customer must check the machine's
direction of rotation using appropriate methods (such as decoupling it from the
driven machine).
CAUTION
It must be ensured that parts which are sensitive to temperature changes (cables
etc.) do not rest against the housing of the machine.
NOTICE
Please note the technical data on the rating plates on the machine enclosure.

Electromagnetic compatibility

NOTICE
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 harm
have an impermissible effect on the supply system and cause impermissible
interference emissions as a result.
