Attention!
It is essential to check the direction of rotation of the fan during the initial commissioning. To do this,
note the direction of the arrow on the fan housing. We will not be responsible under any circumstances
for warrantee for damage caused because the direction of rotation is wrong!
When connected in accordance with the connection diagram, the standard rotary direction

results under factory settings. A change of direction is feasible by exchanging the phase
sequence in the motor connection or through reprogramming.
