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.

Watch the fan wheel of the motor and determine the direction of rotation just before the fan
wheel stops.

If the rotation of the motor must be changed:

Switch any two of the motor phase wires.
