The proper installation and use of frameless cooling fans, including the separation of positive and negative terminals, is crucial to the heat dissipation effect and stability of the equipment.Chungfo, as a professional and experienced wholesale frameless cooling fan manufacturer, will introduce some methods to help you.

First of all, take one of our high quality wholesale frameless fan 12v as an example to tell about the basic knowledge of positive and negative electrodes:Our high quality wholesale frameless dc fan typically have two cables, one for the power input and the other for the ground. The positive terminal is connected to the power supply, and the negative terminal is connected to the ground cable.

Distinguish by color:In general, the red line usually represents the positive electrode (+), and the black or blue line usually represents the negative electrode (-).

To distinguish by length:Sometimes the power cord is longer because it needs to be connected to a power outlet. The ground wire only needs to be connected to the device housing or ground wire connector, and the length will be slightly shorter.

Distinguish by token symbols:Some of our wholesale frameless fan 12v will have markers such as "+" and "-" or logos with arrows indicating direction. The positive electrode will usually be marked with a "+", while the negative electrode will be marked with a "-" or an arrow pointing in the direction of the earth line.
