Page 15: Mechanical Installation
Section 2: Mechanical Installation Note: Daktronics does not guarantee the warranty in situations where the display is not constantly in a stable environment. Daktronics engineering staff must approve any changes that may affect the weather-tightness of the display. If any modifications are made, detailed drawings of the changes must be submitted to Daktronics for evaluation and approval, or the warranty may be void. -
Page 16: Ventilation Requirements
Ventilation Requirements Reference Drawings: Shop Drawings ............Refer to Appendix A Fans mounted in the backsheets toward the top of the display allow for ventilation. Maintain a minimum distance of 3" (7.62 cm) behind the display to maintain proper airflow. Refer to the appropriate Shop Drawing for additional information. If the display cabinet is shrouded or completely enclosed, allowances must be made to compensate for the percentage of material covering the openings in the structure. -
Page 17: Optional Temperature Sensor Installation
The customer must have a qualified structural engineer review the number of attachment points needed and the wall structure to ensure both meet all national and local codes. Daktronics recommends using all clip angles as attachment points. Carefully uncrate the display. Look over all sides of the display for possible damage during shipping. -
Page 19: Electrical Installation
The Daktronics engineering staff must approve any changes made to the display. Before altering the display, submit detailed drawings for the proposed modifications to the Daktronics engineering staff for evaluation and approval, or the warranty will render null and void. -

8. The quick connect cable from the enclosure to the display can be routed through conduit or the display pole. 9. Note: Daktronics engineers strongly recommends that the quick connect cable be secured to protect it from weather of vandalism. -
Page 23: Power
Displays must be grounded according to the provisions outlined in Article 250 of the ® National Electrical Code . Daktronics requires a resistance to ground of 10 ohms or less. Verification of ground resistance can be performed by the electrical contractor who is performing the electrical installation. Daktronics Sales and Service personnel can also perform this service. -
Page 24: Power Installation
Article 250 of the National Electric Code may be used. Daktronics requires that the resistance to ground be 10 ohms or less. If the resistance to ground is higher than 10 ohms, it will be necessary to install additional grounding electrodes to reduce the resistance. -

3. From the quick connect input board, the signal is transferred to the display’s controller via a 20-conductor ribbon cable. 4. From the controller, the signal then travels over 20-conductor ribbon cables from the controller (J11 through J18 provides signal out) to J2 on the driver of the first row of modules in the display. -
Page 31: Display Access
Display Access Display access for all 64mm displays is from the front. To open the display: 1. Locate the four screws that hold the module in place. Two are on top of the module and two are on bottom of the module. -
Page 32: Line Filter
Line Filter You can replace the filter by labeling and removing all connecting wires, and then releasing the attachment hardware. Figure 20: Power Term Panels Modules and Drivers An 8x8 module consists of louvers and two 4x8 LED display boards, each with a driver mounted to the display board. -
Page 33: Controller
The driver is a circuit board responsible for switching the intensity levels of the LEDs. One mounts on the back of each module. To remove a driver board: Open the display as described in Section 4.4. Disconnect all power and signal connections from the driver board. Remove the one #6 nut holding the board in place. - Page 34 2. Disconnect power. 3. Remove all power and signal connections from the board. “Locked” connectors are released by pushing apart the latches, and then carefully pulling them from the jack. When replacing the board, it is helpful to have the cables labeled as to which was removed from which connector. 4.
