1.6 Product Safety Approval
Daktronics ColorSmart scoreboards are ETL-listed, tested to CSA standards and CE-labeled
for indoor use. Contact Daktronics with any questions regarding the testing procedures.
Note: The four-sided scoreboards detailed in this manual are designed to be suspended
above players or spectators, and that creates serious liability considerations. It is
imperative that the roof support system be able to bear the weight of the scoreboard and
all other attachments. Consequently, a licensed engineer must certify the roof support
system. Suspension cables and hoist or attachment structures must also be designed and
certified by a licensed engineer.
Daktronics is not responsible for structures and suspension systems designed or installed
by others.

Mechanical Installation 7
Section 3: Mechanical Installation
Mechanical installation consists of lifting and permanently mounting the scoreboard and any optional
advertising panels or message centers. The mechanical specification drawings listed in Appendix A
show measurements, cable attachment points, and mounting weights for each scoreboard model.
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.
Below is a general overview of the entire installation process. Each step is detailed in the sections that
follow, and the instructions are presented in the general order in which events should occur.
1. Plan and install the hoist or static-suspension structure.
2. Provide power circuit(s) and outlet(s) at the scoreboard location.
3. Provide a power outlet at the control location.
4. Route signal cable from the control location to the scoreboard location, and install the
junction box (if the system is not controlled by radio).
5. Assemble the scoreboard frame.
6. Attach the lower ad panel supports to the frame, if required, and mount the lower
ad panels.
7. Mount the scoreboard sections to the frame and join them at the top.
8. Route and connect all power cords and signal cables around the top of the scoreboard.
9. Mount the upper ad panels or message centers, if required.
10.Mount ad panels atop the message center, if required.
11.Make power and signal connections between message center sections and/or power
connections for backlit ad panels, if required.
12.Attach the corner shrouds.
13.Lift the scoreboard assembly and static-mount, or lower the hoist and attach it to the
scoreboard assembly.
14.Make the final power and signal hookup to each tier of the display (scoreboard tier,
backlit ad panel tier, message center tier).
3.1 Lifting the Scoreboard
Daktronics ColorSmart scoreboards are shipped equipped with a single eyebolt for lifting the
display into place. The eyebolt is located in the center of the top of the scoreboard cabinet.
Daktronics indoor scoreboards use 3/8" eyebolts. Use the single eyebolt at the top of the
scoreboard section only to lift the display into position for assembly.
Note: Eyebolts are intended for lifting only. Do not attempt to permanently support the
display by its eyebolt. Daktronics assumes no liability for damages resulting from
incorrect setup or lifting methods.

8 Mechanical Installation
3.2 Four-Sided Scoreboard Suspension Options
The method by which the scoreboard is to be suspended must be determined at the time of
purchase. There are two primary methods of installing a center-hung scoreboard: creating a
static-hung system or using a hoist. Each method has its own benefits and drawbacks. Refer
to the suspension publication, DD1627665, in Appendix F, and call Daktronics for help in
making the best choice for your installation.
Note: Do not attach items to the scoreboard without prior approval.
To properly review and approve a proposed attachment, Daktronics requires information on
the size, weight, and method by which the item will be attached to the scoreboard.
(Engineering time to review attachments will be charged at a "time and expenses" rate.)
Static Mounting
Static-mounted displays are typically hung with two or four static cables. Two cables may be
used when mounting the scoreboard below a large beam or when the display is centered
between a pair of beams. Four cables are used to further distribute weight.
Note: For either method, the mounting cables must be symmetrically distributed to
maintain a level and a square configuration.
Cable assemblies must have a strength greater than six times the actual load. All other rigging
components must be sized within the working load limits published by the component
manufacturer.
Note: Daktronics strongly recommends that only components from reputable domestic
suppliers be used to permanently suspend the scoreboard.
Remove immediately and do not use any assemblies that show evidence of excessive wear or
broken wires as defined by the component manufacturer.
Follow these procedures for installation:
1. Have a structural engineer certify that the building can safely support the additional
display loading and that the connection points are designed to safely carry the
scoreboard weight.
2. Attach the cable sling to the scoreboard assembly while it is on the arena floor.
3. Hang ends that attach to the ceiling over the sides of the scoreboards. If an end is too
short, attach a rope to the end temporarily so it can be returned from the top.
4. The scoreboard can be lifted into place in a number of different ways.
Note: It is the installer's responsibility to ensure that the installation is safe and that
the display meets OSHA or local regulations.

Mechanical Installation 9
Lifting Method Example: A common method of temporarily lifting the scoreboard is to use a
pair of chain-lift motors mounted on the ceiling. Secure prior approval from the facility
management regarding location and acceptable loads for each rigging point.
1. Attach the chain hoist hooks to the sling master link, or sling to the corner lift tubes.
Be sure the angle of the sling is greater than 45°.
2. Use the chain hoist to lift the scoreboard to the appropriate height.
3. From the lift, retrieve the sling cables draped over the sides of the scoreboard and
attach them to the appropriate locations in the ceiling.
4. Connect to power outlets (and signal junction boxes, if required) in the ceiling.
5. Level the scoreboard by adjusting the turnbuckle on the sling.
6. Lower the scoreboard weight onto the slings.
7. Remove the chain motors.
Electric Hoist System
Installing an electric hoist system is more complex and may expose the customer to greater
liability. Publication SL-03610 in Appendix F discusses recommended minimum hoist
specifications and points that must be considered when selecting a hoist system.
A building engineer must review and approve the combined weight of the
scoreboard, hoist, and a minimum impact factor of 15 percent.
The hoist must be accessible for periodic inspections and maintenance as required by
ANSI and OSHA.
Note: Records of periodic inspections must be on file to be accessible for OSHA
(refer to Section 5.7).
Electrical service and control wiring must be run to the hoist location.
Additional structures in the ceiling are often required to accommodate the hoist.
If an existing hoist is to be used, or if a hoist is to be purchased directly by the end
user, the user assumes all responsibility and liability for the hoist system.
The hoist must be inspected and certified in writing by the hoist manufacturer,
manufacturer's representative, or other qualified hoist inspector.
Daktronics will inspect hoists installed by Daktronics.
Daktronics will certify the scoreboard weight but will require a liability waiver
signed by the customer before the scoreboard is shipped.
Once the hoist is installed according to the specifications of the hoist manufacturer
and the building engineer, refer to Section 3.10 for more information about attaching
the scoreboard to the hoist.
WARNING!
Never ride in or work on or below the scoreboard while the hoist is powered up.
Daktronics recommends having an audible horn warning to indicate that the hoist
system is ON.
Never operate the hoist system during public events or when people are below the
scoreboard.
When running the hoist, the operator must have an unobstructed view from ceiling to
floor (to ensure free scoreboard travel). Hoist operators should be trained according
to the hoist manufacturer's specifications.

10 Mechanical Installation
3.3 Assembly Overview
The assembly kit includes the following:
Floor frame –2 halves, 2 side splice plates, and 4 top & bottom splice plates
Corner shrouds @ 4
Shroud brackets @ 8
Top corner brackets @ 4
Assorted bolts, nuts, washers, and screws
In addition to the scoreboard pieces, an installation may also include:
Upper and lower ad panels
A message center at the top or bottom of the scoreboard
Each scoreboard face section is one piece and must be attached to the structural frame.
The frame is shipped in two parts and requires some assembly. Corner shrouds, which
provide cosmetic covering only, are attached to the display last.
Ad panels may simply be painted metal cabinets that do not need power, or they may be
backlit, requiring a 120 V circuit. An LED message center requires power as well as signal
wiring. The scoreboard itself requires power and signal wiring. The scoreboard tilts outward
at approximately 10°, while the ad panels or message centers are vertical (except for BB-3146
and BB-3147, where the opposite is true). Refer to Section A-A shown on the mechanical
specification drawings in Appendix A.
3.4 Frame Assembly
Reference Drawing:
Optional 4-Side Canvas Assembly.........................................................Drawing A-173611

Field Assembly; 10' x 10' Bolted Frame................................................Drawing B-1102115
Field Assembly; 10' x 10' SS Bolted Frame..........................................Drawing B-1102140
The scoreboard frame is shipped in two sections (refer to Drawings B-1101988 and B-1102115
in Appendix E). Note that each section has two corners with a brace across the corner and
two corners without a brace. The lift tubes in the braced corners will be on the top side. An
optional sheet metal floor may be attached to the top side of the frame sections during
manufacturing.
1. Lay out the two sections with the unbraced sides facing each other and the corner lift
tubes facing up.
2. Connect the sections together in the middle using 1/2" hardware.
3. Attach all six section splice plates using 1/2" hardware. Two splice plates will go on
the sides, while two smaller splice plates will go on both the top and bottom.
Note: If an optional canvas was ordered, attach it to the bottom of the frame using the
provided hook and loop fastener strips and self-drilling screws. Refer to DWG-
173611 in Appendix C for more information on this option.
BB-3146 and BB-3147
For BB-3146 and BB-3147 models, refer to Drawing B-1102140. These models include LED
message centers that require additional “kickers” for support.

Mechanical Installation 11
3.5 Optional Lower Ad Panel Attachment
Reference Drawing:
Bottom 4-Side Ad Panel Mounting.........................................................Drawing A-107664
This step is required only if the scoreboard has ad panels or auxiliary scoreboard displays to
be attached to the bottom. Refer to Drawing A-107664 in Appendix C.
Support brackets are attached to the bottom of the frame, and the ad panel sections are to be
attached to these brackets. The support brackets are designed to be able to support the weight
of the whole scoreboard while sitting on the arena floor.
Note: The bottom ends of the supports should extend about 1/16" beyond the bottom of
the lower ad panels so that the scoreboard's weight is not resting on the ad panels.
1. Raise the assembled frame and support it on sturdy blocks or stands.
2. There are four holes in each corner of the frame on the bottom side. Secure a support
bracket in all four corners using 3/8" hardware.
3. Attach the rear flanges of the ad panels to the support brackets with 3/8" hardware.
3.6 Mounting Scoreboard Sections to the Frame
Reference Drawing:
4-Side Installation Details.......................................................................Drawing A-154598
Top 4-Side, Mounting...........................................................................Drawing B-1102472
Each side of the frame has two mounting angles to which the bottom of each scoreboard
section will be attached. The tops of the scoreboard sections will be joined at their corners by
brackets. Refer to Drawing A-154598 in Appendix E for an illustration of the parts used in
this procedure.
1. Lift one scoreboard section into place on the frame, with the mounting angles inside
the bottom channel of the scoreboard section.
2. Align the holes along the bottom of the scoreboard's rear flange with the 1/4"
threaded inserts on the mounting angles, and install the 1/4" bolts as shown in
Detail A of Drawing A-154598.
3. Ask for assistance as needed to support the scoreboard section and prevent it from
tipping as the second section is lifted into place adjacent to the first and secured to
the frame.
4. Join the two scoreboard sections at their common top corner using a top bracket and
3/8" hardware as shown in Detail B of Drawing A-154598. Once the two sections are
joined, they will not require additional support during assembly.
5. Attach the third scoreboard section to the frame at the bottom and to the second
section at the top corners.
6. Attach the fourth scoreboard section to the frame at the bottom and to the third
section at the top corners.
BB-3146 and BB-3147
In addition to being attached to mounting angles on the bottom of the frame and to each
other with top corner brackets, two LED message centers will be connected to support
“kickers” via angle brackets and 1/2" hardware. Refer to Drawing B-1102472.

12 Mechanical Installation
3.7 Optional Top Ad Panel or Message Center Attachment
Reference Drawing:
Top 4-Side Ad Panel Mounting...............................................................Drawing A-107665
Note: Make sure all power and signal wires are connected on top of the scoreboard
before mounting an ad panel/message center –it will be very difficult to make these
connections once upper display tiers have been added. Refer to Section 4.2.
Drawing A-107665 in Appendix E illustrates the parts used in this procedure. The ad panels
or the message centers are attached to the top of the scoreboard with mounting strips, and
then joined at the top with brackets.
1. Attach the mounting strips to the top of the scoreboard. The mounting strips are
fitted with 1/4" threaded inserts. Two mounting strips are required for each ad
panel/message center.
a. Position a mounting strip inside the top channel of the scoreboard section,
aligned with the holes in the rear flange.
b. Use the 1/4" bolts and tapered washers to attach the mounting strips to the
scoreboards. The tapered washers allow the ad panels/message centers to be
supported in a vertical position while the scoreboard remains tilted out 10°.
2. Lift one ad panel/message center into place atop the scoreboard section, and align
the holes along the bottom of the rear flange with the threaded inserts in the
mounting strips.
3. Insert and tighten 1/4" bolts along the rear flange of the ad panel.
4. Ask for assistance as needed to support the ad panel/message center section and
prevent it from tipping as the second ad panel/message center is lifted into place
adjacent to the first and secured to the frame.
5. Join the two ad panel/message center sections at their common top corner using a
top bracket and 3/8" hardware. Once the two sections are joined at the top, they will
not require additional support during assembly.
6. Attach the third ad panel/message center section to the mounting strips on the top of
the scoreboard and to the second section at the top corners.
7. Attach the fourth ad panel/message center section to the mounting strips on the top
of the scoreboard and to the third section at the top corners.
3.8 Optional Ad Panels on Message Centers
Repeat the mounting procedures detailed in the section above, with one major difference:
the ad panels and message centers are both vertical and do not require the alignment angle

Reference Drawing:
4-Side Installation Details.......................................................................Drawing A-154598
Note: Make sure all power and signal wires are connected on top of the scoreboard
before attaching the corner shrouds. Refer to Section 4.2.
The corner shrouds are metal panels that cover the outside corners of the four-sided assembly
and hide the wiring between sections. Separate shrouds are provided for each display tier.
Refer to Detail C of Drawing A-154598 in Appendix E for corner shroud installation details.
1. Position and attach angle brackets to the side channel of each scoreboard, ad panel, or
message center section with the #10 screws provided.
2. Position each corner shroud across the appropriate corner and mark the locations of
the holes on the angle brackets.
3. Drill 5/32" holes as a guide for the screws.
4. Secure the corner shrouds to the corners with the #10 screws provided.
3.10 Attaching Suspension Cables

The roof of the facility and any structures fabricated for suspending the scoreboard, as well as
the suspension cable slings, must be designed by or inspected and approved by a qualified
engineer. Drawing A-181903 and Drawing A-181935 in Appendix E show recommended
component specifications of cable slings (these are not typically provided by Daktronics).
Note: Refer to Drawing A-268195 for BB-3146 and BB-3147 models.
If the scoreboard is to be static mounted, that is, suspended from fixed cables without a hoist:
1. Attach the cables to the four lift tubes on the corner braces of the frame. The cables
may be connected together to make two attachment points, or all four cables may
attach to the roof trusses or the mounting structure.
2. Hang the top ends of the cables over the sides of the scoreboard to get them out of the
way yet keep them accessible when hooking up.
3. Lift the scoreboard using an appropriate means, such as a chain hoist, to the correct
suspension height.
4. Attach the top ends of the cables to the previously prepared mounting points.
5. Remove the temporary lifting apparatus and level the scoreboard by adjusting the
turnbuckles built into the slings.

14 Mechanical Installation
If the scoreboard is to be suspended from a hoist:
1. Attach the cable sling to the four lift tubes on the corner braces of the frame.
2. Lower the hoist cables and attach them to the master links.
3. Raise the scoreboard 1-2' (305-610 mm) from the floor, and level the scoreboard by
adjusting the turnbuckles built into the slings.
4. The hoist installer must set upper and lower primary limits and all safety limits.
Daktronics recommends maintaining a minimum of 2' (610 mm) between the
scoreboard and the nearest obstruction.
WARNING! Never raise or lower the scoreboard with personnel or equipment underneath!
