Some devices do not allow the motor reverses, when you install phase sequence identification, the motor wiring is required to be correct. Phase sequence indicator shown in the figure is easy to make, firstly, you can use the insulating handle Alligator Clip to hold a phase of power as the starting phase L1. Another two insulated handle Alligator Clips must touch the other two phases of power supply, then you can identify power supply phase sequence by two bulbs' brightness difference.
