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

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

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.

Figure 6: Correct Grounding

Important points about grounding:

• 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.

• Support structure cannot be used as an earth-ground electrode

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

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

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.
