Runout and thrust on the shaft extension of the motor damage the motor.
● Mount the motor without runout and thrust on the shaft extension.
● Observe the specifications on the rating plate.
● Observe the warning and information plates on the motor.
● Remove the anti-corrosion protection thoroughly from the motor shaft. Use commercially
