11 Commissioning
DANGER! Risk of injury and risk of damage to the fan. Before commissioning, read the operating
instructions carefully and check the following:
positioning of the device (tting, possible deformations)
assembly residue and foreign bodies removed from fan area and connected channel
safety devices tted
leakage test carried out
correct performance and correct connection to the electrical installation
correspondence of the connection data with the information on the name plate
DANGER! Risk of injuries to the eyes by residue or dust being swirled out when checking the
direction of rotation. When checking the direction of rotation of the rotor, wear
protective goggles!
DANGER! Live wires and connections!
Risk of injuries from electric current!
Have all electrical work done by a trained electrician only!
If the direction of rotation is wrong, interchange two phases in order to set the correct direction of
rotation.
As soon as you have put the fan into operation, check awless functioning (free movement of the
rotor, measurement of the current consumption, check for possible vibrations and noises).
