Outdoor installation considerations. Notice first, waterproof, of course, is the second, wind outdoor enclosure, the screen is bigger, the steel structure must be more strong, is strict. Third, shockproof, that is, can a few earthquake resistance. Channel steel, from strict requirements for, must be used to make the mouth type, all round with a fixed Angle, screw holes. On both sides with aluminous model board decorate sound. Also do frame with square tube inside. Fourth, lightning protection, grounding electronic components in electronic display outdoor led display to high level of integration, the sensitivity of the jamming is becoming more and more high. Lightning can harm display system by various means, in general, it is directly on screen and then into the ground by the grounding device. In the lightning current through the machine, electricity, heat damage. Solution is equipotential connection, is not grounded or not good grounding of metal shell, the metal sheath of the cable, the metal frame inside the screen into the grounding device, prevent due to feelings of high pressure on these objects or grounding device on thunder into the high potential transfer of equipment caused by internal insulation, cable core. In the area of large display system adds lightning arrester, surge arrester can reduce response appeared on the equipment of overvoltage, limit the lightning invasion wave. Lightning protection rainy day 1, several measures for lightning protection electricity to ensure power supply grounding is good, the display device adopts the structure of common ground that 'three' ( Equipment working grounding, power supply, lightning protection grounding) One way. Note: in strong lightning areas or non-standard building lightning protection field when using our products, please install lightning protection facilities in input side, or you can contact with screen factory customer service staff, promptly provide you with the overall lightning protection scheme 2, positive protection to avoid the possible problems, proactive protection, as far as possible the items away from the power supply may cause harm to the power supply; And also in clean LED screen or system as far as possible to wipe gently, do waterproof, to minimize the possibility of the damage. 3, control use time Suggestions in plum rains season LED large screen used more than once a week at least. Generally open screen, or system at least once a month, lit for more than 2 hours. 4, to prevent the work environment temperature LED display space of the casing seal, air convection ( Suggest adding window shutter rainproof, below the inlet exhaust above) 。 Suggestion: at the time of selection of power supply, power should be reserved 30% allowance, prevent power at work in the process of thermal damage to the power supply. 5, and control the humidity to keep the LED display big screen area or system using the environment humidity, don't let anything in the nature of moisture into your LED large screen area or system. Note: use in wet areas or rainy season, and has been in a working state, the product is not 24 hours to ensure the safety of your system, please use the three prevention treatment of power supply products ( Moistureproof, mouldproof, prevent mist) 。
