What are the preparations before installing the LCD splicing screen

　　1、 Equipment placement: Equipment should be placed reasonably; If installed in a standard rack, chassis, or cabinet, or placed on a stable and flat workbench to prevent the equipment from falling and causing damage due to collision.

　　2、 Cable: Items should not be placed on power lines, signal lines, communication lines, and other cables. The cable should be avoided from being stepped on or squeezed to prevent electrical leakage or short circuits, which may damage the safety of indoor high-definition LCD splicing screens.

　　3、 Signal line connection: When plugging and unplugging the signal line from the device, the device needs to be powered off to avoid damage (damage caused by live plugging is not covered by the warranty).

　　4、 Power supply: It is necessary to use a single-phase three wire AC 220V power supply with protection, and ensure that the entire engineering system uses the same protection; Unprotected power sources cannot be used, and the grounding pin of the power cord must not be damaged.

　　5、 Power outage: Before installing the LCD splicing screen, when moving equipment or performing other work that requires power outage, all power sources should be turned off, including the power switch, unplugging the power plug, etc., to ensure the safety of maintenance personnel, users, and equipment
