380V axial fan has five lines how to take?
Forced wiring easy to burst switch. The operator is also unsafe.
If it is three-phase 380V axial fan, the coil DC resistance is not the same, indicating that the motor is broken, can not be wired
If not, there are two groups of the same, there is a group of different, but also a capacitor, then the axial fan should be a 220V power supply. If you want to change the direction of the fan, you must connect the power cord in the power cord to the other end of the capacitor.
At the same time, the best way to measure the wiring before the axial flow of three lead-out line between the two DC resistance to see if the same. If the same, that is really three-phase 380V power supply,
First look at the nameplate of the axial fan, if the above marked three-phase 380V, it means the need for wiring voltage of 380V three-phase power supply. Any of the two power cords can be changed to change the direction of rotation of the fan.
