Section 1: Introduction
This manual explains the installation of Daktronics multi-section outdoor LED scoreboards and
provides details for maintenance and troubleshooting. For additional information regarding the
safety, installation, operation, or service of this system, refer to the telephone numbers listed in
Section 7. This manual is not specific to a particular installation.
Important Safeguards:
Please read and understand all instructions before beginning the installation process.
Do not drop control equipment or allow it to get wet.
Do not disassemble control equipment or electronic controls of the display; failure to
follow this safeguard will make the warranty null and void.
Disconnect display power when not in use or when servicing.
Disconnect display power before servicing power supplies to avoid electrical shock.
Power supplies run on high voltage and may cause physical injury if touched while
powered.
Do not modify the scoreboard structure or attach any panels or coverings to the
scoreboard without the express written consent of Daktronics, Inc.
Project-specific information takes precedence over any other general information found in
this manual.

Mechanical Installation 11
Section 3: Mechanical Installation
Mechanical installation consists of installing concrete footing and steel beams and mounting the
scoreboard and accompanying ad panels to the beams.
3.1 Footings & Beams
The installation specification drawings listed in Appendix A show the recommended number
of beams and spacing between them. The drawings also indicate the size of beams required to
support the scoreboard at different heights and at various wind speeds. Use the following
table to determine which drawings provide the installation specifications for each model:

The column and footing size dimensions are to assist with estimating installation costs. They
are estimates only and are not intended for actual construction purposes. Be sure that the
installation complies with local building codes and is suitable for the particular soil and wind
conditions. The columns, footings, and all connection details must be designed and certified
by a professional engineer licensed to practice in the state of the scoreboard installation.
Note: Daktronics does not assume any liability for any installation derived from the
information provided in this manual or installations designed and installed by others.
3.2 Lifting the Scoreboard
Larger scoreboard sections and message centers are shipped equipped with eyebolts used to
lift them. The eyebolts are located along the top of the cabinet for each scoreboard or
scoreboard section. Daktronics scoreboards use 1/2" and 5/8" shoulder-type eyebolts mounted
to a 1/8" aluminum plate or steel nut plate.
Daktronics strongly recommends using a spreader bar, or lifting bar, to lift the display.
Spreader bars ensure the force on the eyebolts remains straight up, minimizing lifting stress.

12 Mechanical Installation
Figure 4 illustrates the preferred scoreboard lifting method on the left and an acceptable
alternative lifting method on the right. When lifting the display:
Use a spreader bar if possible.
Use every lifting point provided.
Cables and chains attached to the eyebolts and directly to
a center lifting point, as shown in the right-hand example
in Figure 4, can create a dangerous lateral force on the
eyebolts and may cause the eyebolts to fail. The smaller
the angle between the cable and the top of the display, the
lighter the sign must be to safely lift it. If this method
must be used, ensure a minimum angle between the chain
and scoreboard of at least 45 degrees.
Do NOT attempt to lift the display if the angle is less than
45 degrees. Exceeding load angles or weight limits could
cause the bolts in the scoreboard cabinet to buckle,
resulting in serious damage to the scoreboard or injury to
personnel. Also, loads should be applied directly in the
plane of the eyebolt as shown in Figure 5.
Note: Daktronics assumes no liability for damages resulting from incorrect setup or
lifting methods. Eyebolts are intended for lifting only. Do not attempt to permanently
support the display by the eyebolts.
In typical multi-section installations, the lower scoreboard is installed first and secured to the
support beams. The upper section is then placed atop or above the lower section and attached
to the beams. There may be cables extending from the top of the lower section. Guide these
cables into the hole in the bottom of the upper section for later connection. Refer to Section
4.5 for more information on the power/signal connections between sections.
If installers remove the eyebolts, plug the holes with bolts and the rubber washers that are
used with the eyebolts. Apply silicone or another waterproof sealant to the eyebolt openings.
Also inspect the top and sides of the display for any other holes or openings that may allow
moisture to enter the display and plug and seal those openings.

3.3 Scoreboard Mounting
Mounting hardware includes inner and
outer mounting clamps; clip angles; 1/2-13 x
15" threaded rods; 3/8-16 x 2" bolts, hex nuts
and lock washers; and 1/2" square nuts, hex
nuts, and lock washers. Refer to Figure 6 or
Drawing A-308051 in Appendix A. Each
section of the scoreboard attaches at the top
and the bottom to every beam.
Note: The threaded rods do not pass
through the flanges of the beams, but
instead run along both sides.
1. Using 3/8" bolts, loosely attach the
inner and outer mounting clamps to
the rear flanges of the scoreboard.
Measure the beam spacing and position the clamps to fit on either side of the beams.
2. Insert a 1/2" square nut into each mounting clamp. Screw a threaded rod into each of
the nuts from the rear.
3. Position the scoreboard at the front of the beams with the threaded rods extending
from the rear of the clamps, straddling the beams. Raise the scoreboard section to the
desired height.
4. Slide clip angles over the ends of the rods and loosely install the washers and nuts.
5. Make final adjustments in the positioning of the scoreboard. Tighten the 3/8" bolts in
the mounting clamps.
6. Make sure that the threaded rods are perpendicular to the scoreboard, and tighten all
of the 1/2" hex nuts (Figure 7).

14 Mechanical Installation
Scoreboard Mounting Using Vertical Spacers
Many customers add message centers or advertising panels to the top or bottom of their
scoreboards, and in some cases the depth of the add-on component may not match the depth
of the scoreboard. This will typically be scoreboards that are 8" deep.
To create a uniform appearance for the overall display, Daktronics recommends using
vertical spacers behind the scoreboard so that the front face of the display lines up evenly
with the front face of the added component. The concept is illustrated in Figure 8 and
Drawing A-182909 in Appendix A.
During the installation, spacers are placed between the mounting beams and the back of the
scoreboard cabinet. Spacer size is determined by the height and the extra depth required for
the front surface of the scoreboard to match that of the optional message center or ad panel.
Note: Daktronics does not provide these spacers.
3.4 Scoreboard Protective Devices
Daktronics makes optional protective devices, including screens and netting, to help prevent
damage to the scoreboard due to normal ball impacts.
Note: Some users install devices to protect the scoreboard from projectiles. Scoreboard
protection devices not provided by Daktronics must be approved by Daktronics prior to
installation. Failure to follow this approval procedure will void the scoreboard warranty.
