  • Page 10: Pre-Installation Checklist

    Pre-installation Checklist Verify the following before proceeding with installation: • The display is in good condition after shipping and uncrating. • All clip angles or mounting holes are attached to the support structure. • A straight and square mounting frame is provided for the display. Height variation in any four-foot horizontal section may not exceed ¼-inch.

  • Page 11: Display Mounting

    The number of attachment points needed and the mounting structure must be reviewed by a qualified structural engineer and meet all national and local codes. It is the customer’s responsibility to determine the proper wall mounting method and location. Daktronics requires using bottom mounting angles or all mounting holes as attachment points.

  • Page 13: Power 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 be rendered null and void.

  • Page 14: 3.3 Power Requirements

    The power J-box on the back of the display is provided with ¾” threaded holes for use with ¾” conduit. If necessary, knockout/drill holes are provided in the display cabinet itself when not using the enclosure. 3.3 Power Requirements Each display uses one 120 VAC or 120/240 VAC single phase power source. Proper power installation is imperative for proper display operation.

  • Page 15: Power Connection

    250 of the National Electric Code may be used. • Resistance to ground 10 ohms or less: This is required by Daktronics for proper display performance. If the resistance to ground is higher than 10 ohms, it will be necessary to install additional grounding electrodes to reduce the resistance.

  • Page 16: Figure 6: 120 Vac Power Termination

    Option 1: Terminating hot, neutral, and ground wires at the J-box Display power is connected to the power termination enclosure on the back of the display. Complete the following steps to terminate the hot, neutral, and ground wires at the termination enclosure.
