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 affect the weather-tightness of the display. Prior to making any modifications, detailed drawings of the changes must be submitted to Daktronics for evaluation and approval, or the warranty will be null and void.

Daktronics is not responsible for installations or the structural integrity of support structures done by others. The customer must ensure a qualified structural engineer approves the structure and any additional hardware.

2.1 Pre-Installation Checklist

Verify the following before installation:

• 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 4' (1.2 m) horizontal section must not exceed 1/4" (6.3 mm).

• Adequate support is provided for the display so that the structure will not yield at any unsupported

points after mounting.

• Leave 4" (10.2 cm) of unobstructed space above the display so the eyebolts can be removed. No clearance is required once the eyebolts are removed.

• Maintain clearance around the display to allow unobstructed air flow through the vents and fans and to allow access to internal components.

• Assure the display cabinet has no holes (accidental or intentional) that could allow water to enter the display.

• Check that all display modules are fully latched into the display cabinet.

2.2 Support Structure Requirements

The installer must ensure that the mounting structure and hardware can support 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 Galaxy® displays. The information contained in this section is general information only and may not be appropriate for all installations. Refer to Figure 2 for basic display set ups.

Mounting plans need to take into account the ventilation system and face-mounted light sensor. In general, the entire front of all displays must be completely unobstructed to allow for air flow and internal access. Displays contain fans that pull air in from the lower vents and exhaust it out adjacent vents.

Mechanical Installation 3

Also, keep in mind the location of mounting clips and the clearance needed for the power and signal terminations on the back of the display shown in Figure 2. Display height and wind loading are also critical factors to consider. Consult the Shop Drawing, which is included with the display.

2.3 Display Mounting

To maintain the structural integrity of the display cabinet, keep a 90-degree angle between the cabinet and the lifting method.

If damage occurs because of improper lifting procedures, the warranty will be void.

General Mounting Procedure

Use Lift Bar and ALL Eyebolts

1. Lift the display into position on the support structure, following the example in Figure 3. Note: Do not attempt to permanently support the display by the eyebolts.

2. Weld or use 1/2" grade-5 (or stronger) bolts and hardware to secure ALL of the clip angles to the support structure as shown in the Shop Drawing which is included with the display. Note: Alternative mounting methods are acceptable as long as all bolt locations are used.

Figure 3: Correct Lifting

3. Refer to Section 3 for power routing and to the appropriate communication manual for signal connections to the display.

4. After installation is complete, carefully inspect the display for any holes that may allow water to seep into the display and seal any openings with silicone.

If the eyebolts on the top of the display were removed, plug the holes with bolts and the rubber-sealing washer that was removed with the eyebolt unless an overhead structure protects the area.

Section 3: Power Installation

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 null and void.

3.1 Conduit

Daktronics does not provide 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).

For power, displays have either a J-box or a 3/4" conduit access hole located near the lower right on the back of the display. For signal, displays have signal input quick connects or etched drilling guides for conduit.

3.2 Overview of Power/Signal Connection

1. Power to the display is terminated externally in most cases. Section 3.6 shows external wiring examples.

2. Possible methods for signal termination are shown in the various communication manuals.

3. Power is routed to the display through a fused disconnect switch capable of opening all ungrounded

power conductors. Install the disconnect within the line of sight of any personnel performing maintenance on the display, unless it can be locked in the open position.

Note: Displays are equipped with circuit breakers that carry a UL489 or UL1077 (IEC 60947, VDE 660) rating. These devices are intended only to protect the components within the display.

4. Route power conductors from the disconnect to the display through conduit following local code

specifications.

5. Display power terminates either to the J-box or internally at the power termination panel.

6. Connect the grounding conductor to the grounding lug on the back of the display.

7. Route signal cable to the signal termination enclosure. Ground the enclosure to an isolated earth-ground

connector (when required).

8. Route signal into the enclosure through conduit. The knockouts on the enclosure require the use of 3/4"

conduit.

9. Route signal quick-connect cables from the enclosure to the display either 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 cables be secured to protect them from weather or vandalism.

Mechanical Installation 5

3.3 Power Requirements

Install this display according to all applicable local and national electrical codes. This includes proper grounding and bonding of the display.

Do not connect the display to any voltage other than that listed on the Daktronics product label.

Displays use single-phase power. Proper power installation is imperative for display operation. Find power specifications on drawings shipped with the display.

Important Notes:

• Daktronics recommends that a separate circuit be run to the electronic display(s) to isolate it and prevent any issues that could be caused by line voltage fluctuations or high frequency noise on the power line caused by other types of equipment. A separate circuit also makes display maintenance and troubleshooting easier. Daktronics assumes no liability for any issues caused by line voltage fluctuations or other improper power conditions if these recommendations are not followed.

• Size conductors of circuits that deliver power to the display according to national and local electrical codes so the power distribution system delivers full-load power to the display while maintaining a voltage within 5 percent of the utility nominal voltage.

Main Disconnect

Daktronics requires using a power disconnect switch with the display. Use a disconnect so that all ungrounded conductors can be disconnected near the point of power connection.

Locate the disconnecting means either in a direct line of sight from the display or so it can be locked in the open position. This ensures that power is not reconnected while service personnel work on the display.

3.4 Power Grounding

Ground displays according to the provisions outlined in local and national electrical codes.

Install these displays using the provided ground and neutral conductors. The power cable must contain an isolated earth-ground conductor.

Do not connect neutral to ground at the disconnect or at the display. This violates electrical codes and voids the warranty.

3.5 Display Grounding

Connect the display system to earth ground as shown in Figure 4. Proper grounding 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

• 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, install additional grounding electrodes to reduce the resistance. The grounding electrode should be installed within 25' (7.6 m) of the base of the display and must be connected to the ground lug on the back of the display. Refer to Figure 4.

6 Power Installation

• Follow local and national codes: The material of an earth-ground electrode differs from region to region

and for conditions present at the site. Consult any local and national electrical codes that may apply.

• Support structure cannot be used as an earth-ground electrode: Daktronics does not recommend using

the support structure as an earth-ground electrode; concrete, primer, corrosion, and other factors make the support structure a poor ground.

Note: The support structure may be used as an earth-ground electrode only if designed to do so. A qualified inspector must approve the support structure and grounding methods.

• 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 any local and national electrical codes may be used.

3.6 Power Connection

Power is most often terminated externally to the J-box on displays. However, larger displays require power to be terminated internally in the Power Termination Panel.

For Displays With an External Power Termination J-box

Terminating hot, neutral, and ground wires at the J-box:

1. Route the power cable through conduit to the rear of

the display and into the power termination J-box (the J-box contains 3/4" threaded conduit fittings).

2. The J-box contains two or three wires plus a ground

coming from the interior of the display. These wires are pre-terminated to the power termination panel inside the display.

3. Inside the external J-box, connect the power wires to

the wires coming from the display interior using wire nuts. Refer to Figure 5 for 120 VAC and Figure 6 for 120/240 VAC.

Note: The following colors are used for the pre-terminated wires:
