3.5 LED Wall Components An    LED Wall has the following components Modules = Cabinet + Pixel cards Frame structure (3.3 Framesets for Bundles) Power bar (3.5.7 Power Bar) Figure 4: LED Wall Components Module The module consists of eight Pixel cards and a cabinet. For information on Type A and B modules/cabinets, see 3.5.2 Cabinet.
PAGE 21
Cabinet Each cabinet has a combination of structural and technological functionalities that constitute a robust, stable, protective, and safe LED Wall. Additionally, the LED Wall is easy to build, maintain and service through the cabinet system. Figure 9: Type A Cabinet – Front Type A Cabinets have two connectors for power (Power supply socket), one on the top and one at bottom of the case (see Figure 10). Type B Cabinets have only one connector for power (Power supply socket) on the bottom of the case.
PAGE 22
3.5.2.1 Corner Alignment Pins At the top of each FE Series cabinet are two special corner locating pins (Figure 11, A) – with a diagonal inside the corner pin. This design allows the cabinets to be securely stacked upon each other for up to 15 layers – reaching at total height of 5 meters. A Figure 11: Corner Alignment Pins 3.5.2.2 Screw Connection for Cabinets The Screw connections between the cabinets guarantee quick installation and easy maintenance.
PAGE 23
3.5.2.3 Grip Handles The grip handles (Figure 13) are bolted into the cabinet, middle-center, left and right from the hub board. These provide for easy handling during installation and maintenance in the openposition, and conveniently collapse into the cabinet when not in use (Figure 13, Figure 14).
PAGE 24
3.5.2.4 Cabinet Hanger Pins Cabinet hanger pins (Figure 15) are attached on the back of the cabinet (Figure 16) and secured on the inside of the cabinet (Figure 17, H). If used as fixed installation, optional matched connectors can be adopted to connect the Corner alignment pin and support frame.
PAGE 25
3.5.2.5 Power Supply Socket The Power supply sockets (Figure 18, A) distribute the power for each column of modules in the LED Wall. The sockets are male and female adapters at the top and bottom surfaces of the cabinet. The sockets interconnect two cabinets of a column (Figure 19). The socket is connected to the Power distribution unit (PDU) (wiring, C). The sockets wire to the PDU (Figure 20, D) and ground (E) on the cabinet.
PAGE 26
Pixel Card The Pixel cards display segments of the picture on the front. On the back, the Pixel card has three components, which keep the Pixel card in position on the cabinet:    3 corner click-pins (A) 4 magnets (B) 1 Pixel card connector (C) A B C Figure 22: Pixel Card – Front Figure 21: Pixel Card – Back Connections on the Hub board and the Cabinet For installation and operation, the Pixel card needs no cable connections to the Hub board or Cabinet.
PAGE 27
Black Masks The Black masks cover and protect the electronic surface between the LEDs of the Pixel card PCB. In combination with our high-end LED-chips (A), the mask (B) is necessary to get the best black-values, which result in a high contrast ratio of the screen.
PAGE 28
Hub Board The Hub board distributes the signals, data and power to other hardware components in the cabinet, such as Receiving card, power supply and Pixel cards. Each Hub board has a Power supply unit (PSU) and a Receiving card. Hub Board Interfaces The Hub board has several interfaces to distribute power and data. The Hub Board front (Figure 25) has the following interfaces:    8 Pixel card network interfaces (A): For data transmission and power supply to Pixel cards.
PAGE 29
Power Supply In each module, one Power supply unit (PSU) connects through a Power distribution unit (PDU) to the power input. The following components contribute to the power supply of a module:    1 Power supply unit (PSU) (A) 1 Power distribution unit (PDU) (B1) with PDU shielding (B2): The PDU shielding protects the high voltage components from being touched by accident.
PAGE 30
Signal Lights The Signal lights are on the back of the module (Figure 29). They indicate the status of the module. The three lights are red, green and blue. Figure 29: Signal Lights on the Back of the Module The Signal lights are fixed on a PCB (A) to the inner backside of the cabinet and connected to the Hub board with the Signal light cable (B). B A Figure 30: Signal Light Interface Connected to Hub Board Power Bar The Power bar is the LED Wall component for the distribution of data and power.

3.6 Ventilation Requirements Caution! Risk of fire, injuries and product damage due to overheating of the system.  Ensure proper ventilation and air flow around the system.  Never block the ventilation spaces around the LED Wall. Keep them free at all times.  Never install the system air-tight into an alcove. Always leave the required minimum ventilation space.
PAGE 32
Minimum Ventilation Spaces for On-Wall Installation Figure 33: Ventilation Space for On-Wall Installation D min. distance to ceiling 500 mm E min. distance to floor 700 mm Heat Dissipation The FE Series is provided with a highly efficient LED chip to reach low power consumption, less heat production and a long working life. The modules are designed fan-free which ensures a super quiet operation. The whole housing of the module is designed as heat sink.

9 MAINTENANCE 9.1 Routine Maintenance Caution! Risk of electric shock. Always disconnect the FE Series LED Wall from the power outlet before performing any maintenance work. Regular use After you put the LED Wall into use, use it 25–30 h and 5-times a month so the LED Wall stays dry and delivers a stable performance. Daily Check the LED Wall visually for physical damages. 9.2 Regular Cleaning Caution! Risk of product damage by moisture or water. Do not clean the system with water.
PAGE 74
9.3 Power System Maintenance Caution! Risk of electric shock. Do not use the LED Video Display if you detect any faults in the power supply. Daily Check all cables visually for physical damages. Every six months Caution! Risk of electric shock. Only qualified personnel with an electrician certificate are allowed to perform maintenance work. Clean the interior of the power distribution cabinet and fasten screw connections. 9.
PAGE 75
9.5 Front Service The following instruction will guide through the exchange of all replaceable parts. All replacements require the removal of the Pixel cards first. Replacement of power supply and Receiving cards require additionally the removal of the hub board. Notice  It is essential to wear a glove at least at the hand that might touch the front of the LED cabinet, because the LEDs are very sensitive to the greasy film on the skin, and ensure ESD protection.
PAGE 76
Put the removed Pixel card into its foam form. Figure 110: Foam Forms for Pixel Cards After removing all Pixel cards, the cabinet looks like shown in Figure 111. Install new Pixel cards Take the Pixel cards out of the spare part package. Place the Pixel card carefully by hand or Service Tool to the screen. Figure 111: Cabinet without Pixel Cards Load the calibration data on the new Pixel card (see 7.5 Update the Calibration Data after Installing All Pixel Cards).
PAGE 77
Caution! Risk of damaging the Hub board. When reinstalling the Hub board, do not bent the two Powergood-connectors. With bent connectors, the whole module cannot work properly. Change the Receiving Card For servicing the Receiving card, you first need to remove the Pixel cards (see 9.5.1) and the Hub board (see 9.5.2). Pull the Receiving card straight off the Hub board. Be careful not to damage their connectors. Replace the Receiving card.
PAGE 78
Replace the Power Distribution Unit Loosen the four screws (D). D Remove the PDU shielding (B2). B2 Pull the PDU straight and carefully. Be careful not to damage the connectors to the PSU or the wiring (E). E F Disconnect the cables from the PDU's terminal (F). Figure 116: Removing Shielding & PDU Replace the PDU. To reinstall the replaced PDU, follow the steps in reverse order. Replace the Power Supply Unit To replace the PSU, remove the Power distribution unit (PDU) first.
