The motor fan cover has an installation indicator. See
fig. 1. Based on the motor cooling air, it indicates the
direction of rotation of the motor.
Before the motor is started for the first time or if
the position of the indicator has been changed, the
indicator function should be checked, for instance by
moving the indicator field with a finger.
To determine whether the direction of rotation is
correct or wrong, compare the indication with the table
