Mechanical Installation 9
Section 3: Mechanical Installation
Mechanical installation consists of lifting and permanently mounting the scoreboard, statistics panels,
and game/shot clocks. The mechanical specification drawings listed in Appendix A show the
recommended number and spacing of wall anchors for specific scoreboard models.
Be sure that the installation complies with local building codes.
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.
3.1 Lifting the Scoreboard
Most Daktronics Tuff Sport scoreboards and statistics panels are shipped equipped with at
least one eyebolt for lifting, as well as pre-drilled holes along the top and bottom of each
cabinet for wall attachment. Eyebolts are located along the top of the cabinet for each
scoreboard or scoreboard section. (The smaller game/shot clocks do not require eyebolts and
are not equipped with them.) Daktronics indoor scoreboards use 3/8" eyebolts.
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.
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°.
Do NOT attempt to lift the display if the angle is less than 45°.
Figure 4: Lifting Methods

10 Mechanical Installation
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
without the suspension mounting kit (see Section 3.3).
Small Daktronics scoreboards are not equipped with
eyebolts, and instead use two lifting straps that encircle
the scoreboard. It is recommended to use a spreader bar
with the straps.
3.2 Scoreboard & Statistics Display Mounting
1. Use the eyebolt(s) at the top of the scoreboard
frame to lift the display into position for mounting.
Note: For statistic displays, verify the correct
HOME or GUEST display by looking at the label on
top of the cabinet to determine whether it should
be mounted to the left or right of the scoreboard.
2. Secure the display to the wall by attaching
mounting hardware through all holes on the top
and bottom rear flanges of the display to a pre-
drilled hole in the wall (Figure 6).
For mounting locations, weights and hardware
suggestions, refer to the model-specific mechanical
specification drawings listed in Appendix A.
Due to the variety of wall materials used in sports facilities, Daktronics cannot anticipate a
user‟s individual installation needs or provide mounting hardware suitable for every
installation. Choose a method of installation that will safely support the weight of the display.
3.3 Suspension Mounting Kit
One of several mounting options with the Tuff Sport scoreboards is a suspension lift eye
installation, which requires a special mounting kit (part # 0A-1237-0016). Contact Daktronics
about any installation that involves permanently suspending the scoreboard.
1. Secure the mounting angle with the 3/8" nut to each side of the scoreboard with the
included screws. Install the eyebolts into the nut on the mounting angle.
2. Attach suspension cables to the eyebolt using a shackle and pin (all of this equipment
is provided by others).

Mechanical Installation 11
Notes:
1) Daktronics recommends that two cables be used at each end of the scoreboard.
2) Cables and hardware must be specified by a licensed engineer.
3) Do not attach suspension hardware to ad panels –attach to top of scoreboard.
4) This installation method must not be used to support scoreboard with message
centers and/or backlit ad panels attached.
5) The total weight of scoreboard and accessories must not exceed 500 lb (223 kg).
Similar to the eyebolts used to lift the scoreboard, the suspension eyebolts have a maximum
angle at which they can safely support the display. The ideal angle is perpendicular to the top
of the scoreboard, but this angle may extend up to 30° out to either side of the display.
Refer to Drawing A-148644 in Appendix C for more information.
3.4 Shot Clock Mounting
Single-sided shot clocks may be mounted to a wall in the same manner as a scoreboard or
statistics display. Multi-sided shot clocks are frequently mounted to vertical backstop
supports. Refer to Drawing A-91230 in Appendix C for game/shot clock mounting
information.
Note: Daktronics does not supply the hardware or brackets to mount shot clocks to
backstops and is not responsible for the integrity of suitability of mounting systems
manufactured and installed by others.
3.5 Corner Mounting
Certain scoreboard models may be mounted in a corner, rather than flat against the wall,
using a special mounting bracket kit. For more information on the corner mounting option,
refer to Drawing A-150831 in Appendix C.
3.6 Ad Panel Mounting
Refer to Drawing A-147668 in Appendix C for typical ad panel mounting (similar to
Scoreboard & Statistics Display Mounting shown above) or Drawing A-156134 for
instructions on mounting ad panels to the top or bottom of a scoreboard.
3.7 Scoreboard Protective Devices
Daktronics Tuff Sport displays have been designed so that a normal basketball or volleyball
impact will not damage the LEDs or display cabinet, reducing the need for protective devices.
Some users, however, may still wish to have additional protection from other projectiles, and
in these cases, Daktronics provides optional protective devices. Refer to the Protective Screen
Installation Instructions (ED-5423), available online at www.daktronics.com/manuals for
more information about installing protective devices.
Note: 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.

Electrical Installation 13
Section 4: Electrical Installation
CAUTION: Only qualified individuals should access the electrical components of the display and its
associated equipment. It is the responsibility of the electrical contractor to ensure that all electrical
work meets or exceeds local and national codes.
Daktronics engineering staff must approve all changes or the warranty will be void.
4.1 Installation Overview
The diagram shown in Figure 7 illustrates a typical wired setup between a scoreboard and
the control system. Daktronics part numbers are shown in parentheses. Drawings A-124686,
A-124688, A-125415, and A-125417 in Appendix E also show power and signal layouts.
Note: Control signal cable and some junction boxes are not provided as part of this
system and can be purchased locally or from Daktronics.

The diagram shown in Figure 8 illustrates a typical wireless setup between a scoreboard and
the control system. Refer to Section 6.2 for more information about the wireless radio option.
4.2 Power
Each scoreboard features a 120 VAC power cord with a three-prong plug. Install a grounded
receptacle near the equipment so that the power cord can easily reach it. The control console
requires a 120 VAC receptacle and uses less than 1 A of power.
Displays operating on 230 VAC are also available, and they are shipped equipped with a
universal power plug.
Grounding
Connect the scoreboard to earth ground. Proper grounding assures reliable equipment
operation and protects the equipment against damaging electrical disturbances and lightning.
Daktronics recommends a resistance-to-ground of 10 ohms or less. The electrical contractor
performing the electrical installation can verify ground resistance. Daktronics Sales and
Service personnel can also provide this service. The grounding connection on the power
cord‟s three-prong plug connects to the shell of the scoreboard.
Note: The customer must properly ground the outlet according to local and national
codes. Failure to ground the outlet voids the warranty for the scoreboard.
