For information on Type A and B modules/cabinets, see 3.5.2 Cabinet. Figure 5: Type A Module – Front View Figure 6: Module – Back Side Figure 7: Type B Module – Open Figure 8: Type A Module – Open © NEC Corporation 2019 20 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. This allows for the frame cover top to be placed directly on top of the housing for perfect closure of the frame. A B Figure 10: Type A and Type B Cabinet © NEC Corporation 2019 21 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. Each cabinet has two sets of Screw connections:  two sets of Allen screw anchors – left and top (Error! Reference source not found., B)  two sets of Counter plates – right and bottom (C) This design allows modules to interconnect tightly in order to create a seamless LED Wall display. C B Figure 12: Screw Connections for Cabinets: Screws and Counter plates Section 6.3.2 explains how to interlock two cabinets. © NEC Corporation 2019 22 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 open position, and conveniently collapse into the cabinet when not in use (Figure 13, Figure 14). D Open Closed Figure 13: Grip Handle in Open and Closed Positions Figure 14: Grip Handles in Use © NEC Corporation 2019 23 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. Figure 15: Cabinet Hanger Pin Figure 16: Installing Cabinet Hanger Pins H Figure 17: Cabinet Hanger Pin Connectors © NEC Corporation 2019 24 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. The PDU, in turn, connects to the Power supply unit (F) via the hub board's power supply connector (see also Figure 26, D, p. 28). B A C Figure 18: Power Supply Sockets – Top and Bottom F D E Figure 19: Connected Sockets Figure 20: Sockets Wired to PDU behind HUB © NEC Corporation 2019 25 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 21: Pixel Card – Back Figure 22: Pixel Card – Front 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. Three types of interfaces help to secure Pixel cards within the cabinet.  Click-pin interfaces (D): counter-part to the corner click-pins on Pixel card; ensure the right position of the Pixel card on the cabinet.  Level screws (E): counter-part to the magnets on the Pixel card; enable to adjust possible protrusion of the Pixel card to smoothen the surface of the LED Wall.  Pixel card network interface (F): counter-part to Pixel card connector; for data transmission and power supply to the Pixel card. D E F Figure 23: Pixel Card Interfaces on Hub Board and in Cabinet © NEC Corporation 2019 26 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. A B Figure 24: LED Chip and Usage of the Black Masks © NEC Corporation 2019 27 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.  2× 2Ethernet ports (B): For data transmission from Hub board to Hub board. (Only the left Ethernet port transmits data. The right Ethernet port has no function.)  16 screw connections to cabinet (C): To secure the Hub board in the cabinet. A B C Figure 25: Hub Board – Front The backside of the Hub board has several interfaces for data and power distribution (Figure 26):  4 pin connectors to Power supply unit (D): Distribute the power from PSU to the Hub board, e.g. for the Pixel cards or Receiving card.  1 Power-good-connector (E): Sends status of power supply to monitoring software. Be careful when re-assembling the module, the connectors bend easily.  1 Receiving card (F): Receives data and signal input via the Ethernet cable from the external controller. They process the signals and forward them to the Pixel cards.  1 Signal light cable (G): Forwards the status input of the module to the Signal lights on the back of the module. E G D F Figure 26: Hub Board – Back © NEC Corporation 2019 28 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. Do not remove while power is connected!  1 Power supply interface to Hub board (C): Counter-part to the Hub board's four pin connector to supply the Hub board with power. B2 B1 B A C Figure 27: Behind Hub Board –Power Supply with Wired PDU with PDU Shielding The PDU connects to the PSU via three pin connectors (D) for each PSU interface (E). E D Figure 28: Pin Connection from PDU to PSU © NEC Corporation 2019 29 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. It is located at the bottom of the LED Wall and connects to each row of modules via the Network and power supply socket. The Power bar also serves as cable conduit: The cables for power supply and data transmission run inside the Power bar from Hub boards and the terminals to the exit points on the back of the Power bar. Figure 31: Power Bar with Cable Exit Point © NEC Corporation 2019 30 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. Notice For installation conditions deviating from the information given below, more calculations regarding the air flow and cooling of the system are necessary. If you have questions, please contact NEC DISPLAY SOLUTIONS, see 1.2 Service & Support in Europe.

The modules are designed fan-free which ensures a super quiet operation. The whole housing of the module is designed as heat sink. Cooling The required ventilation depends on each particular project. Depending on the structural design and environmental temperature it may be necessary to add an external cooling. To integrate the ideal, energy-efficient air conditioner for the LED display, you have to determine the capacity or size you need. This is important for two reasons: An undersized unit will not cool adequately the LED display in extremely hot weather. An oversized air conditioner can also adversely affect your comfort. The unit may switch on and off too often, without running long enough to dehumidify the LED display properly or cool the space uniformly. And it will consume more energy than necessary. Info The ideal environment temperature for the LED display is 10 – 25 °C. © NEC Corporation 2019 32 4 ACCESSORIES 4.1 Power Supply and Connecting Cables Power Supply for Power Bar Internal: The internal electricity wiring is connected to a terminal in the Power bar.
