Stage LED Rental Screen Installation: A Complete Standardized Process
Installing stage LED rental screens requires balancing efficiency, safety, and performance. The following is a complete standard operating procedure, from initial preparation to final acceptance, adapted to the rapid setup requirements of rental scenarios.
3-5 days before installation, site surveys, steel frame design, and equipment checks must be completed. Site surveys should measure stage dimensions and load-bearing capacity; for outdoor installations, wind speed levels must be assessed, with wind speeds ≤6 Beaufort scale being suitable for hoisting. Power outlet locations should also be marked, ensuring one 380V distribution box is reserved for every 10㎡ of screen area, with a power redundancy of ≥30% to prevent power shortages. Steel frame design should be based on the screen weight (approximately 30kg/㎡), with hoisting steel frames having a load-bearing capacity of ≥50kg/㎡. For stacked installations, anti-slip protective mats should be laid, and CAD drawings should clearly indicate installation points and wiring layout. During equipment checks, the number of cabinets and module integrity should be verified upon unpacking, and the power supply and receiving card functions should be tested. Specialized installation tools such as torque wrenches and spirit levels should be prepared to ensure cabinet splicing accuracy.
On-site installation proceeds in the following order: steel frame construction, cabinet splicing, wiring, and grounding/lightning protection. Steel frame construction begins with fixing the main load-bearing beams, followed by the installation of horizontal supports, with an error tolerance of ±5mm. Outdoor installations require the addition of windproof cables for enhanced stability. Cabinet splicing proceeds from bottom to top, layer by layer. The bottom cabinets are aligned first and secured with quick-release fasteners. Each cabinet should be installed in ≤10 seconds, with adjacent cabinets having a gap of ≤0.2mm. A spirit level is used to calibrate flatness. During wiring, power and signal lines must be laid separately, with a spacing of ≥10cm to avoid signal interference. American standard cables and surface-mounted sockets are used to prevent loosening. Signal lines support any routing, meeting the wiring requirements of curved screens. Outdoor screens require connection to a ground wire with a resistance of ≤4Ω and the installation of lightning arresters to prevent lightning damage to the equipment.
Debugging and acceptance are the final critical stages of installation. During basic debugging, after powering on, the uniformity of module brightness is tested. White balance is adjusted through software to ensure color consistency, and the splicing points are checked for bright or dark lines, eliminating splicing marks. Signal testing requires connecting multiple signal sources such as HDMI and SDI to test the smoothness of switching. Outdoor screens require manual water spray testing to verify waterproof performance. Safety acceptance involves checking the stability of the steel frame and the firmness of the cabinet fixation, and conducting simulated human touch tests to ensure there is no looseness before approval.
After installation, operators need to be trained in basic troubleshooting skills, such as switching to a backup source when the signal is interrupted and quickly replacing modules in case of module failure. Attention should also be paid to detailed issues during the installation process, such as sealing the gaps between outdoor screen cabinets with waterproof sealant to prevent rainwater penetration; and protecting power and signal cable interfaces to prevent dust from affecting signal transmission. Strictly following installation specifications not only ensures the stable operation of the stage LED rental screen but also enhances the stage visual effects, laying the foundation for a successful performance.
