3.1 Preparing for Power Connection
• A power termination box is provided on the back of the display. If the installation of the
display does not allow for the use of this enclosure, refer to Section 3.6 for information
on the internal wiring for the power.
• 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.
• Power conductors from the disconnect to the display should be routed through conduit
in agreement with local code.
• Display power will terminate to the display at the external power termination J-box
mounted to the back of the display.
• Connect the grounding electrode conductor at the grounding lug on the display at this
time.
3.2 Conduit
Daktronics does not include the conduit. Separate conduit must be used to route:
• Power
• Signal IN wires to the display, when applicable
