1. Connect the live wire (power cord) to the switch panel.

2. Then connect the fire line of the exhaust fan with another wire, and the zero line is generally on the top surface.

3. Connect this zero wire with another wire of the exhaust fan.

As long as the incoming zero line is connected in parallel with the two zero lines left by the electrician, the incoming live wire is connected to the power supply of the control switch, and the four live wires are connected to the switch respectively. As long as you pay attention to the power of the switch, you should jump off the power. Also pay attention to check whether the main power has been turned off when answering, and pay attention to safety.
