Use modules from the same production batch on one LED screen to avoid visible color differences. Do not connect the LED module directly to 220V AC. Ensure that the DC power polarity is correct. Disconnect the main power supply before installing or removing modules, power cables or signal cables. Avoid excessive pulling, bending or twisting during installation and maintenance. Do not allow sweat, water or other liquids to contact the LED module during maintenance. Do not use galvanized steel plates or galvanized square tubes as the mounting structure. A painted iron cabinet or frame is recommended. Do not touch the LED surface directly to avoid electrostatic damage. Protect the module edges and corners from impact to prevent LED damage. For outdoor installations, ensure proper waterproof sealing around the screen structure and cabinet. Inspect grounding and lightning protection systems periodically.
