2.2 Support Structure Design
Support structure design depends on the mounting methods, sign size and weight. The structure design
is critical; only a qualified individual should mount the sign. Sign 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.
The installer is responsible to ensure the mounting structure and hardware are capable of
supporting the sign and agrees with local codes.
Before beginning the installation process, verify the following.
· The mounting structure provides a straight and square frame for the sign.
· The mounting structure supports the sign without yielding at any unsupported points after
mounting.
· Clearance: 3O of unobstructed space is available below the sign for filter removal from the sign. 1
¼O of unobstructed space is available above the top of the sign.
Fans mounted in the bottom of the sign allow for ventilation. Maintain a minimum distance of 3O
(7.62cm) below the sign to maintain proper airflow. Refer to the appropriate shop drawing for
additional information.
If the sign cabinet is completely enclosed:
· Provide 6 square inches of unobstructed opening per module to ensure adequate cooling.
· Make allowances to compensate for the percentage of material covering the openings in the
structure.
· For adequate cooling, the cabinet may require forced ventilation. If the enclosed cabinet must use
forced ventilation, it must ventilate at a rate of 10 cubic feet per minute per module (10.6O x 10.6O
active area).
Failure to comply with these requirements voids the Series AB-1010 sign warranty.
Daktronics typically offers two
display configurations, single face
displays and 2V displays. Figure 6 illustrates each of these two
display types.
A 2V display consists of two
single face units, one master and
one echo. The two sided of this
display may be mounted at any
angle between 0 and 90 degrees.
An interconnect harness used to
power the echo unit is coiled up
inside the master unit. Refer to
Drawing B-139876 for your
sign’s specifications.
2.5 Lifting the Sign
The top of the sign is equipped with eyebolts that are used to lift the unit. Take special care to ensure
that the rated load of the eyebolts is not exceeded. Refer to the information at the end of this section
labeled Eyebolts to determine the allowable load of the eyebolts.

Before beginning the installation process, verify the following items.
· The mounting structure will provide a straight and square frame for the sign. Height variation in
any four-foot horizontal section may not exceed ¼- inch.
· The mounting structure
will not give way at any unsupported points after the sign is mounted.
The back of the sign uses 3x3 mounting clips at the
locations shown in the Shop Drawings; one set is
ounted to the back of the display and another set is

Proper power installation is imperative for proper display operation. The following sub-sections give
details of display power installation.
Grounding
Displays MUST be grounded according to the provisions outlined in Article 250 of the
National Electrical Code
The display system must be connected to earth-ground. Proper grounding is necessary for reliable
equipment operation. It also protects the equipment from damaging electrical disturbances and
lightning. The display must be properly grounded or the warranty will be void.
The material of an earth-ground electrode differs from region to region and from conditions
present at the site. Consult the National Electrical Code and any local electrical codes that may
apply. The support structure of the display cannot be used as an earth-ground electrode. The
support is generally embedded in concrete, and if in earth, the steel is either primed or it corrodes,
making it a poor ground.

. Daktronics recommends a resistance to ground of 10 ohms or less.
Electrical Installation
Branch Circuit Grounding
A grounding electrode at separate structures/displays shall not b
e required where only one
branch circuit supplies the structure and the branch circuit includes an equipment grounding
conductor for grounding the non-current-carrying parts of all equipment.
Power Installation
There are two considerations for power installation; installation with ground and neutral
conductors provided and installation with only a neutral conductor provided. These two power
installations differ slightly, as described in the following paragraphs:
Installation with Ground and Neutral Conductors Provided
For this type of installation, the power cable must contain an isolated earth-ground conductor.
Under this circumstance, do not connect neutral to ground at
the disconnect or at the display.
This violates electrical codes and voids the warranty. Use a disconnect so that all hot lines and

Signal travels from the Venus 1500 controller to the Venus 1500 Display Receiver (V15DR) located
inside the sign. Refer to Drawings A-148859, A-148870, A-148878 and A-148884. The signal
junction boxes for each row of modules receives the data sent by the V15DR and distributes it to the
appropriate drivers. The drivers in turn distribute the signal to the display modules.
4.3 Power Overview
Power routes from the power disconnect to the panel board within the display. From there, power
routes to the display drivers; the drivers distribute the power to individual components within the
display. Refer to the Schematic.
