1. LED modules are powered by DC +5V (operating voltage: 4.2-5.2V). AC power is strictly prohibited. The positive and negative terminals of the power supply must not be reversed (Note: Reversing the connection will damage the product and may even cause a serious fire).
2. LED display screen power supply voltage: 220V±10%; Frequency: 50HZ±5%.
3. Ensure reliable grounding and reliable isolation between the ground wire and neutral wire. Keep the power supply away from high-power electrical equipment.
4. If short circuits, tripping, burning wires, or smoke are observed, do not repeatedly test with the power on. Promptly investigate the problem.
5. Maintain a stable power supply and ensure proper grounding to prevent lightning strikes. Do not use the display in severe weather conditions, especially during strong thunderstorms.
6. Power must be supplied to the large screen in stages, as the maximum power output of the entire screen can impact the entire power distribution system.
7. LED displays should not display a full white image at maximum brightness for more than half an hour to avoid excessive current, overheating of the power cord, damage to LEDs, and shortening the lifespan of the display. It is recommended to primarily play dynamic videos.
8. During use, LED displays should not be continuously turned on and off; there should be at least a one-minute interval between the two operations.
9. Non-professionals should not touch the internal wiring of the LED display screen to avoid electric shock or damage to the wiring. If problems occur, please have a professional inspect and repair it.
