5.12 Checking the direction of rotation
NOTICE
Motor damage from overheating
Limited fan cooling capacity, caused by incorrect rotation direction, causes the motor to overheat.
► Check the direction of rotation using the rotation direction arrow on the fan of the motor.
► If the rotation direction is incorrect, switch 2 of the 3 phases.
► When doing so, make sure that the air flow is sucked through the ventilation grille, and directed
over the motor to be cooled.
