Daktronics engineering staff must approve any changes that may affect the weather-
tightness of the display. If any modifications are made, detailed drawings of the changes
must be submitted to Daktronics for evaluation and approval, or the warranty may be void.
Daktronics is not responsible for installations or the structural integrity of support
structures done by others. The customer is responsible for ensuring that a qualified
structural engineer approves the structure and any additional hardware.
2.1 Support Structure Requirements
The installer is responsible for ensuring that the mounting structure and hardware
are capable of supporting the display, and the structure follows all local codes.
Because every installation site is unique, no single procedure is approved by Daktronics for
mounting Galaxy®displays. The information contained in this section is general information
only and may or may not be appropriate for this particular installation. Refer to Figure 3 for
basic display set-up. Refer to Drawing B-310431 for installation details.
A qualified individual must make all decisions regarding the mounting of this display.
Support structure design depends on the mounting methods, display size, and weight. In
general, both faces of the display need to be unobstructed to allow for air flow and internal
access. Also keep in mind the location of the mounting plates and the power/signal
termination shrouding on the sides of the display. Display height and wind loading are also
critical factors to be considered. The following information can be found in the Shop
Drawings listed here:
•Size and weight information
•Mounting hardware information

Reference Drawing:
Power Specs, AF-3400-20-DF-*......................................................................Drawing A-305814
3.1 Conduit
Daktronics does not include the conduit. Separate conduit must be used to route:
•power.
•signal IN wires to the signal termination enclosure, when applicable.
•signal OUT wires to a second set of displays.
The power J-box and the power end of the display are provided with 3/4” threaded holes for
use with conduit. Unthreaded knockout holes are provided in the signal enclosures as well. If
not using the provided enclosures, use the openings provided in the display cabinet.
3.2 Overview of Power/ Signal Connection
Following is a brief summary of the power and signal connections to the display.
1. Openings are provided on the display for termination of both signal and power. If
the installation does not allow for the use of the power J-box, refer to Section 3.5 for
diagrams on internal power termination.
2. Possible methods for signal termination are shown in the manual for the specific
communication type.
3. Route power to the display through a fused disconnect switch capable of opening all
ungrounded power conductors. Install this disconnect within the line-of-sight of any
personnel performing maintenance on the display. If the disconnect is located out of
sight of the display, it must be capable of being locked in the open position.
Note: Displays are equipped with supplemental protection devices that carry a UL1077
(IEC 60947, VDE 660) rating. These devices are only intended to protect the components
within the display. Suitable devices must be used for the equipment and feeders
supplying power to the display.
4. Power conductors from the disconnect to the display should be routed through
conduit in agreement with local code.
5. Display power will terminate to the display at the power termination J-box or
directly to the power termination panel located on the right end of Face A.

Power Installation
8
6. Connect the grounding electrode conductor at the grounding lug near the J-box on
the right end of Face A.
7. Signal cable is routed to the signal termination enclosure. A grounding electrode
may also be connected there (when required).
8. Signal into the enclosures must be routed through 1/2"conduit.
9. The signal quick-connect cable from the enclosure to the display is routed into the
shrouding on the left end of the display cabinet.
Note: Daktronics strongly recommends that the quick-connect cable be secured to protect it
from weather and vandalism.
3.3 Power Requirements
Conductors of circuits delivering power to a Daktronics display shall be sized in
accordance with NEC and local electrical codes so that the power distribution
system is capable of delivering full load power to the display while maintaining a
voltage within 5% of the utility nominal voltage.
Each display uses a 120VAC or 120/240 VAC single-phase power source. Proper power
installation is imperative for proper display operation. Power specifications for various
display sizes can be found on Drawing A-305814 in Appendix A. The following sub-sections
provide details for display power installation.
Main Disconnect
The National Electrical Code requires the use of a lockable power disconnect near the
display. Provide a lockable disconnect switch (knife switch) at the display location so that all
power lines can be completely disconnected. Use a 3-conductor disconnect so that both hot
lines and the neutral can be disconnected. The main disconnect should be mounted at or near
the point of power supply connection. A main disconnect is to be provided for each supply
circuit to the display.
The disconnecting means must be located in a direct line-of-sight from the display or outline
lighting that it controls. This requirement enables a worker to keep the disconnecting means
within view while working on the display.
Exception: Disconnect components that are capable of being locked in the open position may
be located elsewhere.

Power Installation
9
3.4 Grounding
These displays are installed with ground and neutral conductors provided. 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 would violate electrical codes and void the warranty. Use a disconnect so that all hot
lines and neutral can be disconnected. The National Electrical Code requires the use of a
lockable disconnect within sight of or at the display.
The display system must be connected to earth-ground (Figure 6). 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.
Important points about grounding:
•Follow local and national codes: 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.
•Support structure cannot be used as an earth-ground electrode: The support is
generally embedded in concrete. If embedded in earth, the steel is either primed or it
corrodes, making it a poor ground.
•One grounding electrode for each display cabinet: One grounding rod is necessary for
each display cabinet. Other grounding electrodes as described in Article 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. The grounding
electrode should be installed within 25 feet of the base of the display. The grounding
electrode must be connected to the ground lug on the back of the display.
