Power Installation 13
3.6 Power Routing in the Display
A general power routing, shown in Figure 16, is summarized as follows. The numbers in this
list correspond with the numbers in the diagram.
1.
Power terminates to the J-box on the right end of the display or internally to the
power termination panel.
2.
If terminating at the J-box, power continues through pre-terminated wires to the
power termination panel, which includes the transformer and filter.
3.
From the termination panel, power travels through the transformer which adjusts
power to appropriate voltage for use by the controller.
4.
Power is routed from the power panel to the power supplies/filters which run the
modules.
5. Power is also sent to the fans and to the thermostat.
Note: Power supplies are preset to proper voltage levels. Depending on the pixel count and
LED color, either 3.6 VDC or 5.3 VDC power supplies are used to power the modules.
Contact Daktronics Customer Service for correct voltage settings.
