Page 13: 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. The 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 14: Support Structure Design
Display height and wind loading are also critical factors. It is the customer’s responsibility to ensure that the structure and mounting hardware are adequate. Daktronics is not responsible for the installations or the structural integrity of support structures done by others. -
Page 15: Ventilation Requirements
Ventilation Requirements Reference Drawing: Shop Drawings................ Appendix A Fans are mounted to the back sheet for ventilation. Cool air is brought in through the bottom half of the sign and then the fans in the back exhaust hot air. Refer to Figure 8 and the appropriate Shop Drawing for fan locations. -
Page 16: Display Mounting
It is the customer’s responsibility to determine the proper wall mounting method and location. Daktronics requires using all clip angles or mounting holes as attachment points. 1. Carefully uncrate the display and inspect each side of the display for possible damage that may have occurred during shipping 2. -

Page 22: 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. The display system must be connected to earth-ground. Proper grounding is necessary for reliable equipment operation. -
Page 23: 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. -
Page 24: Main Disconnect
The 133mm/171mm, AF-3400 large character displays are designed for quicker signal and power connection to the display. There are seven different methods of communication and, depending on the particular display, Daktronics provides a separate manual for explaining the connection to the signal termination enclosure. -
