How to install P3.91 indoor LED display?

In order to let more friends understand the installation of P3.91 indoor LED display, as a professional LED display manufacturer in the industry, it is our responsibility and responsibility to introduce to friends the correct installation method of P3.91 indoor LED display. The following are the installation instructions and precautions for indoor LED display magnets, please refer to:

Make a steel frame structure (made according to the size of the drawing), and then fix the finished shelf on the wall or hang it up.

First connect the module power cord to the power supply, each power supply connects two one-to-three or three one-to-two power cords. According to the manufacturer's configuration number, pay attention to the positive and negative polarity. The red wire is connected to the positive pole and the black wire is connected to the negative pole. Then fix the power supply in the corresponding position and fix it according to the drawing position.

Connect the power supply directly to the 2.5 square cable, and pay attention to the live wire and the neutral wire not to be reversed. Usually, the red wire is connected to the live wire (L), the blue wire is connected to the neutral wire (N), and the yellow wire is grounded. The wiring sequence must be uniform and cannot be crossed;

Fix the receiving card in the corresponding position and fix the position according to the drawing. Connect the power cord of the card to the output terminal of the power supply in the same way as the power cord of the module. The power terminal of the receiving card is marked with positive and negative poles or 3-6V and GND. The GND terminal is connected to the black wire, and the 3-6V terminal is marked to be connected to the red wire. Do not twist it. Then insert the long flat cable into the receiving card. There are many sizes of long flat cables. Pay attention to the order of length according to the distance between the card and the module. Do not insert the cable backward.

Generally, sockets are fool-proof, and it is not easy to reverse plug. Then connect the receiving cards in series with a network cable. Now the network port of the receiving card basically has no difference between input and output.

The previous old card should be in the order from left to right. The serial connection sequence of the network cables should be U-shaped or N-shaped, and should not be crossed randomly;

Place the magnet on the module. Generally, there are 4 magnets on each module (that is, 4 magnets on the diagonal). The standard configuration of general manufacturers is 4 magnets per module. According to the size of the module and the size of the field module, the actual weight of the magnet is subject to the carrying capacity of the module. Insert the short cable into the output terminal of the module (for the output of the module to the input terminal of another module).

Fix the modules on the steel frame in order, pay attention to the upper, lower, left, and right spacing during installation, do not dislocation, and the flatness should be consistent. The long cables from the receiving card to the module are arranged in order from top to bottom. Start the installation from top to bottom. Each module must have a cable and power cord connection, which cannot be omitted. After the installation is complete, you can start debugging.
