SP Series Rental LED Screen Cabinet Operation Guide: Assembly, Curving, and Maintenance

Rental LED screens are widely used for concerts, exhibitions, conferences, stage performances, and other live events. Efficient cabinet assembly, flexible screen configuration, and convenient maintenance are essential for ensuring smooth installation and reliable operation.The SP Series rental LED screen cabinets support different assembly configurations, including flexible cabinets, standard cabinets, angled cabinets, and 500 × 1000 mm cabinets. With their cabinet locking mechanisms and adjustable curvature locks, users can assemble LED screens to meet different event and stage design requirements.This guide provides step-by-step instructions for bending flexible cabinets, connecting different cabinet types, adjusting curvature locks, creating inward and outward curves, and performing LED module and power supply maintenance.How to Bend a Flexible Rental LED Screen CabinetFlexible LED cabinets allow users to create curved rental LED screens for stage backdrops, exhibitions, and other event applications.Follow these steps to bend a flexible cabinet:1. Remove the cabinet locking clips before bending.2. Hold the cabinet handles firmly with both hands.3. Press the spring tabs at the upper ends of the handles.4. Carefully bend the cabinet to form the desired curved shape.5. Observe the graduated scale next to the spring tabs while bending.6. Use the scale readings to control the cabinet's curvature.Pay close attention to the scale during adjustment to achieve the desired bending angle.How to Connect Flexible LED CabinetsProper alignment is important when connecting flexible cabinets to build a rental LED wall. The cabinets can be connected horizontally and vertically.Horizontal Cabinet ConnectionBring the side edges of the cabinets close together.Align the cabinet edges and ensure that the display surfaces are level and flush.Insert the side locking pins into the corresponding locking holes.Press the handles to secure the locking mechanism.Lock the lower locking mechanism as well.Check the cabinet alignment and adjust the position as needed.Insert and secure the locking pins completely.Repeat these steps when connecting additional cabinets. Check the surface alignment throughout the assembly process to maintain a consistent display plane.Vertical Cabinet ConnectionWhen connecting flexible cabinets vertically, follow these steps:1. Position the upper cabinet above the lower cabinet.2. Align the locating holes on the bottom of the upper cabinet with the locating pins on the top of the lower cabinet.3. Lower the cabinet so that the locating pins fit into the corresponding holes.4. Insert all three locking pins.5. Secure all three pins and check that the cabinets are firmly connected.Ensure that the locating pins are correctly aligned and all three locking pins are fully secured before continuing the installation.How to Connect Standard Rental LED CabinetsStandard LED cabinets are suitable for assembling flat rental LED screens for concerts, exhibitions, conferences, and other event applications.Follow these steps to connect standard cabinets:1. Bring the side edges of the cabinets close together.2. Align the cabinets and ensure that the display surfaces remain level.3. Insert the locking pins into the corresponding locking holes.4. Secure the locking pins.5. Check that the cabinets are properly aligned and firmly connected.Repeat the process for the remaining cabinets to complete the rental LED display.How to Adjust the Curvature LockThe curvature lock is used to adjust and secure the cabinet angle when creating curved LED screen configurations.Follow these steps to adjust the curvature lock:1. Open the operating lever on the curvature lock.2. Check the graduated scale and adjust the curvature to the desired setting.3. Press the lever downward to lock the curvature setting.4. Check the two curvature locks on the side of the cabinet.5. Adjust both locks to matching angles according to the scale.Ensure that the two curvature locks have consistent settings before proceeding with cabinet assembly.How to Create Inward and Outward Curved LED ScreensBy adjusting the curvature locks to different scale settings, users can create inward-bending or outward-bending configurations during cabinet assembly.Inward-Bending Cabinet ConnectionTo create an inward-bending configuration:1. Adjust the curvature locks to the required negative scale setting.2. Bring the cabinet sides together.3. Align the cabinets and connect them using the designated locking mechanism.4. Secure the locking pins.5. Check the resulting screen curvature.The negative scale setting allows the cabinets to be connected in an inward-bending configuration, as demonstrated in the operation video.Outward-Bending Cabinet ConnectionTo create an outward-bending configuration:1. Adjust the curvature locks to the required positive scale setting.2. Bring the cabinet sides together.3. Align the cabinets and connect them using the designated locking mechanism.4. Secure the locking pins.5. Check the resulting screen curvature.The positive scale setting allows the cabinets to be connected in an outward-bending configuration, as demonstrated in the operation video.Always refer to the scale markings on the actual cabinet when adjusting the curvature.How to Connect Angled Rental LED CabinetsAngled LED cabinets are designed for screen configurations that require angled joints or right-angle connections.Standard Connection of Angled Cabinets1. Bring the side edges of the cabinets close together.2. Align the cabinets and keep the display surfaces level.3. Insert the locking pins into the corresponding locking holes.4. Secure the locking pins.5. Check that the cabinets are properly aligned and connected.Creating a Right-Angle Connection with Angled CabinetsWhen using angled cabinets to create a right-angle connection, adjust the locking components as follows:1. Remove the curvature lock.2. Remove the spacer block from the angled locking pin.3. Reinstall the spacer block in the inward-facing position.4. Bring the angled cabinet sides together vertically.5. Ensure that the angled edges fit closely together.6. Insert the locking pins and secure them.7. Lock the lower locking pins in the same way.Check that all locking points are secured and the angled edges remain closely aligned.How to Connect 500 × 1000 mm Rental LED CabinetsThe SP Series also includes 500 × 1000 mm LED cabinets for building rental LED screens in different sizes and configurations.Follow these steps to connect the cabinets:1. Adjust the curvature lock to the required angle.2. Bring the side edges of the cabinets close together.3. Align the cabinets and ensure that the display surfaces remain level.4. Insert the locking pins into the corresponding locking holes.5. Secure both locking pins on the side of the cabinet.Once both side locking pins are fully secured, the cabinets can be connected as required to assemble the rental LED display.Rear Maintenance: Removing and Installing an LED ModuleRear maintenance allows technicians to remove and reinstall LED modules from the back of the rental LED screen cabinet.Removing an LED Module from the Rear1. Rotate open the locking plates along the upper and lower edges of the module.2. Hold the module handle and push the module forward to release it from its mounting position.3.
