NOTICE
Incorrect direction of rotation.
Risk of damage to the machine!
● Operation in the wrong direction of rotation can destroy the machine in a short time! Prior to
start-up, ensure that the machine is operated in the right direction.
● Determine the intended direction of rotation with the arrow (stuck on or cast).
● Jog the motor briefly.
● With a phase rotation tester, check if the wiring corresponds to the correct direction of rotation.
If the rotation of the motor must be changed:
● Switch any two of the motor phase wires.
