Power Installation 7
3.3 Power Installation
The Daktronics Fuelight ™ displays are installed using the provided ground and neutral
conductors. For this type of installation, the power circuit must contain an isolated earth-
ground conductor. 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
ungrounded conductors can be disconnected.
To connect power to the display:
1. Connect power to the power harness (“pigtail”) inside the display, refer to Figure 6
for an example.
The power harness has a 5-pin plug at one end and three wires: black, white, and
green/yellow. The plug is connected to the mating plug on the transformer and
allows for easy disconnection of the power harness.
2. Use wire nuts to connect power wires to the power harness.
