Warning!
Avoid damaging the motor and compressor when checking the direction of
rotation of the drive motor!
► The coupling may not yet connect the motor and compressor when
checking the direction of rotation of the drive motor.
Secure the electric switchgear so as to prevent the compressor drive motor
from being switched on accidentally.
When checking the direction of rotation of the compressor driving motor pay
attention to the conditions for switching the compressor on.

Motor
The compressor drive motor is started directly and then switched off again by
forcing the digital outputs. Before starting, check that the coupling hub (motor
side) is seated tightly. It is not required to increase the speed for checking the
direction of rotation.
Notice
Before commissioning of the compressor drive motor, be sure to check the
manufacturer information, e.g. for lubrication of the motor.
► The manufacturer information is part of the product documentation.
If the direction of rotation of the motor is wrong, it should be corrected while
the electric switchgear is secured to prevent the motor from being switched on
accidentally. Then the motor must work at least 1 hour unencumbered and
free from errors. This is important in order to dry out residual moisture in the
motor (caused during transport or storage).
The coupling protection must be in place during this start-up period as
required by the labour safety regulations.
After checking the direction of rotation of the drive motor, the coupling may be
connected with the motor.
