Section 2: Mechanical Installation
Read the Mechanical, Power and Signal Installation sections before installing the display(s).
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 that the structure follows all local codes.
Support structure design depends on the mounting methods, display size, and weight.
Because every installation site is unique, no single procedure is approved by Daktronics for
mounting GalaxyPro
information only and may or may not be appropriate for this particular installation. Refer to
Figure 2 and Figure 3 for basic display set-ups.
Mounting plans need to take into account the ventilation system for the specific display size.
In general, the front of all displays needs to be unobstructed to allow for air flow and internal
access. Small displays contain fans on the bottom that pull air in from the lower vent and
exhaust it out the top vent. Displays 64 pixels high and larger need unobstructed area in the
back to allow for fans expelling air through the hoods as shown in Figure 4.
Also keep in mind the location of the mounting clips
and the clearance needed for the power/signal
terminations on the back of the display as shown in
Figure 5. Display height and wind loading are also
critical factors to be considered. This information can
be found in the Shop Drawings in Appendix A. Be
sure to consult the drawing for the appropriate pixel
matrix size.

The display is in good condition after shipping and uncrating.
•
•
A straight and square-mounting frame is provided for the display.
Height variation in any four-foot horizontal section may not exceed ¼-inch.
•
Adequate support is provided for the display so that the structure will not yield at
any unsupported points after mounting.
• Clearance of 4" of unobstructed space above the top of the display is allowed to
remove the eyebolt. Note: No clearance is required once the eyebolt is removed.
•
Clearance around the display is maintained to allow unobstructed air flow through
the vents and fans and to allow access to internal components.
2.2 Display Mounting
In order to maintain the structural integrity of the display cabinet, the 90° angle between the
cabinet and the lifting method must be maintained.
Do not lift combined sections by the eyebolts.
The eyebolts and interconnect bolts are not strong
enough to support the weight of multiple sections.
If damage occurs because of improper lifting
procedures, the warranty will be void.

2.3 Optional Temperature Sensor Mounting
If an optional temperature sensor will be used with this display, see Appendix C for
mounting and signal connections.
Mechanical Installation 7
Read the Mechanical, Power, and Signal Installation sections before installing the
display(s).
Only a qualified individual should terminate power and signal cable at this Daktronics
display.
All proposed changes must be approved by Daktronics engineering staff or the warranty will
be rendered null and void.
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 (if not using the provided interconnect cable).
Most displays are provided with unthreaded knockouts on the back for use with ½” conduit.
The 16 pixel high displays have a J-box on the back for power termination.
Section 3: Power Installation
3.2 Overview of Power/ Signal Connection
Following is a brief summary of the power and signal connections to the display.
1. Power to the display will be terminated internally in most cases. Section 3.5 shows
the internal wiring diagrams.
2. Possible methods for signal termination are shown in the manual for the specific
communication type.
3. Power is routed 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 overcurrent protection devices that carry a UL489 or
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 internally at the power termination panel.
6. Connect the grounding electrode conductor at the grounding lug on the back of the
display. With sectional displays, connect one grounding lug to earth ground and run
the bonding jumper between display sections.
Power Installation 9
7. Signal cable is routed to the signal termination enclosure. When a ground cable is
provided with the enclosure, ground the enclosure to an isolated earth ground
connector.
8. Signal into the enclosures must be routed through conduit. The knockouts in the
enclosures require the use of ½" conduit.
9. The signal quick-connect cable from the enclosure to the display can be routed
through conduit or through the display pole if power is not also routed in the display
pole.
Note: Daktronics strongly recommends that the quick-connect cable be secured to protect it
from weather or vandalism.
3.3 Power Requirements
Do not connect the displays to any voltage other than that listed on the Daktronics product
label.
Important Note: 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 size may be constructed to use either single-phase or three-phase power, with
the exception of the 16 high displays which use only single-phase power. Proper power
installation is imperative for proper display operation. Power specifications for various size
displays can be found in Appendix A. The following sub-sections provide general details of
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 disconnect so that all hot lines and the
neutral can be disconnected. The main disconnect should be mounted at or near the point of
power 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
3.4 Grounding
This sign is to be installed in accordance with the requirements of Article 600 of the National
Electrical Code and/or other applicable local codes. This includes proper grounding and
bonding of the sign.
Displays must be grounded according to the provisions outlined in Article 250 of the
National Electrical Code
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 if the disconnect is not located within sight of the display.
The display system must be connected to earth-ground as shown in Figure 14. Proper
grounding is necessary for reliable equipment operation. It also protects the equipment from
damaging electrical disturbances and lightning. Daktronics requires a resistance to ground of
10 ohms or less. The display must be properly grounded or the warranty will be void.
®
.
Figure 14: Correct Grounding of Display
Important points about grounding:
• Resistance to ground 10 ohms or less
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 (Figure 14).
• Follow local and national codes
region to region and from conditions present at the site. Consult the National Electrical
Code and any local electrical codes that may apply.
Power Installation 11
: This is required by Daktronics for proper display
: The material of an earth-ground electrode differs from
• Support structure 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.
• One grounding electrode for each display face
: The grounding electrode is typically one
grounding rod for each display face. Other grounding electrodes as described in Article
250 of the National Electric Code may be used.
Note: Each section of a sectional display has a ground lug but only one lug per display
face needs to be connected to the ground rod. A bonding jumper runs between sections.
Grounding Sectional Displays
In addition to following all the requirements of general
grounding, sectional displays have a few additional
requirements.
Each section of a sectional display will contain a ground
lug. Only one of these lugs needs to be connected to
earth ground. Refer to Figure 15.
A bonding jumper is present in the top section. Connect
this to the bottom section by unscrewing the nut,
placing the loop end of the cable over the screw, and
replacing the nut. Refer to Figure 16.

3.6 Power Routing in the Display
Following is a basic overview of power routing. Check exact power routing for a specific
display on the Layout Drawing found in Appendix A.
A general power routing, as shown in Figure 25, can be summarized as follows.
1. Power terminates internally to the power termination panel.
2. Power travels through the transformer which adjusts power to the appropriate voltage
for the controller.
3. Power is routed through filters to the power supplies which provide power to the
modules.
4. Power is also sent from the last breaker on the power termination panel through a filter
to the fans and the thermostat.
Note: Power supplies are preset to the proper voltage: 12-13.1VDC.

4.1 Primary Mirror Display Interconnections
If this display is a two-sided primary/mirror display, a quickconnect cable will be provided to connect the signal between the
two display faces. This cable has right-angle plugs at each end.
These need to be installed with the cable facing either down or to
the side to provide the least stress on the cable. In addition, secure
the excess cable to the supports to prevent damage from weather or
vandalism (Figure 26).
Larger displays will have more than one quick-connect per display
face. Be sure to connect all necessary signal interconnections
(Figure 27).
