THREE-PHASE MOTOR WIRING DIAGRAM

For single-phase motors and motors with special connections, follow the diagrams supplied with the motor
Check the connection of the motor to the ground and the fastening of the lugs.
Make sure that the power cable cannot interfere with or rub against the rotating parts of the fan. Shut the motor terminal box.
Check the fastening of the stuffing boxes.
Once all the checks are complete, power and start up the fan.
Check the fan rotation direction and the intensity used by the motor, using a current clamp. The measured intensity must be
below or equal to the intensity on the motor plate. If the measured intensity is greater than the plate intensity, the load loss is
too low in the case of a centrifugal fan or too high in the case of an axial flow fan.
Check fan vibrations upon starting up. They must comply with ISO 14694 (see starting values in table 2). If they are
not correct, please contact the manufacturer.
