NOTICE
Incorrect direction of rotation.
Risk of damage to the motor!
• Operation in the wrong direction of rotation can destroy the machine in a short time!
Prior to starting-up make sure 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.
• Watch the fan wheel of the motor and determine the direction of rotation just before
the fan wheel stops.
If the rotation must be changed:
• Switch any two of the motor phase wires.
