Introduction

The step-by-step instructions in this guide are a general reference for installing the LED Display. If any details in this document are unclear, please contact your reseller for more information.

Before Installing

Ensure there is no direct airflow from air conditioning or heating vents blowing on the LED Display.
Avoid installing the LED Display in places with high humidity.
Due to high power usage, always use power cords specifically designed for this product.
Wood may split if holes are not pre-drilled before installing the Wall Mount Brackets.
Ensure the deviation of the wall surface is < 5 mm.
Wear protective gear, such as gloves and protective shoes, when handling the LED Display.
Due to the size and weight, it is recommended that two or more people handle it.

Wall Mounting

There are two types of the Wall Mount Brackets for installing our LED Display: the Wall Mount Brackets with the Wall Mount Connector Plate and those without the Wall Mount Connector Plate. Before the installation, please ensure the Wall Mount Brackets supplied in the case match the ones illustrated in Appendix A.

1. Please take a moment to check the following when deciding the installation location.
   However, for the best results, it is recommended to ask your reseller or licensed professional to install the LED Display.
   • The wall space.
   • The wall type.
   • The power consumption.
   • The installation type.
   • Cable pathways between the Cabinets, and between the Cabinets and System Control Box.
   NOTE: 
   Refer to Appendix A for the detailed instructions on mounting the Wall Mount Brackets, including minimum space requirements.
2. Install the first Upper Wall Mount Bracket with the provided screws (M8 x 80 mm Expansion).

   NOTE: It is recommended to use a laser or torpedo level.
4. After mounting the first and second Upper Wall Mount Brackets to the wall, secure them with the Wall Mount Connector Plate using the six provided screws (PM6 x 10 mm).
   
5. Repeat Step 2~4 for the remaining Upper Wall Mount Bracket(s).
6. Install the Lower Wall Mount Brackets in the same manner as the Upper Wall Mount Brackets.
   NOTE: You can also install the Upper Wall Mount Brackets, hang the screen, and then install the Lower Wall Mount Brackets for a more precise fit.
7. After installing the Upper and Lower Wall Mount Brackets, please mark the following holes and pre-drill them for the System Control Box (see Appendix B for the position of the mounting holes and cable access holes).

Installing the Cabinets

Before installing the Cabinets on the Wall Mount Brackets, it is recommended to refer to the wiring diagram provided in Appendix B first to decide how you want to route the Cables for the power and network connections to the Cabinets.
Additionally, the rubber hole plugs installed on the Cabinets are used to protect the Power and Network Cables from rubbing against any pointed edges. After installing all Cabinets, use a knife to cut the rubber hole plugs to size along the cross according to the thickness of the Cables.

1. Place each section of the Cabinet on stable furniture that can safely support them.
   Start with the Cabinets from the center, then move to the right and left sides of the Wall Mount Brackets (see Appendix B to identify Cabinet sections and installation sequence).
   NOTE:
   • One Cabinet is divided into separate sections. You can identify these Cabinet sections by the labels on each section or the package.
   • The arrow marks on each Cabinet section should be pointing up.
2. Attach the Cabinet sections together with the provided screws (M8 x 20 mm).
3. Carefully lift the assembled Cabinet onto the center of the Upper Wall Mount Brackets.
   
4. Ensure the Mounting Brackets sit securely on the Wall Mount Brackets as shown below.
   
5. Repeat Step 1~2 for the second Cabinet.
6. Install the first and second Cabinets together with the provided screws (M8 x 20 mm).
7. Check for unevenness of the Cabinets by rubbing the cross section between each Cabinet. If the cross section is not aligned, loosen the M8 screws slightly and tap the Cabinets until the cross section is flat.
8. Repeat Step 1~7 for the remaining Cabinets, ensuring that the Mounting Brackets sit securely on the Wall Mount Brackets, and that the Cabinets are properly secured together.
   NOTE: Refer to Appendix B to identify the Cabinets and installation sequence.
9. After installing all Cabinets, cut the rubber hole plugs to size along the cross with a knife (see Appendix B for the position of the hole plugs).

Connecting and Installing the System Control Box

The left and right sides of the System Control Box are pre-installed with its Covers in the factory. The main system control board is on the right.
The safety wires are used to prevent the Right Cover from falling when accessing the System Control Box. Please ensure that the safety wires are never removed.
Use caution as the System Control Box panel is separated into two pieces with wires attached.
Before installing the System Control Box, the Power and Network Cables of the Cabinets at the lowest row must be routed through the holes provided in the System Control Box from behind (see Appendix B for example system wiring diagram).

1. At the lowest row of the Cabinets, connect the connector of the longer Power Cable to the power connector of the Cabinet. Then, connect one end of the longer Network Cable to the network port of the Cabinet.
   NOTE: 
   • The longer Power and Network Cables are supplied in the case.
   • Ensure to match the corresponding letters on the Cables to the Cabinets (A to A, B to B, C to C, and so on).
2. After connecting all the Power and Network Cables, carefully thread them through the holes provided in the Cabinets and run the Cables behind the Cabinets from the top cable access hole through the bottom cable access holes.
   Avoid sharp bends in the Cables.
    The rubber hole plugs must always be placed in the holes.
3. Carefully place the System Control Box on stable furniture that can safely support the System Control Box.
4. The rubber hole plugs installed on the rear of the System Control Box are used to protect the Cables from rubbing against any pointed edges. Use a knife to cut the hole to size along the cross.
5. To open the Right Cover, slowly bring the supplied Maintenance Tool near the surface of the Right Cover where the steel plate is located. Then, the Right Cover should detach from the System Control Box magnetically.
   DO NOT try to remove or disconnect the safety wires. Please ensure that the safety wires are never removed.
   
6. Remove the Left Cover by gripping the top edge of the Cover and pulling it toward you. The Left Cover should simply lift away.
