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.
