Route power and signal cables into the scoreboard
from the rear. There are two plastic plugs for
conduit connection in the back. All power and
signal wiring terminates at the driver enclosure.
Drawing A-293354 illustrates the 16-column
driver used in Daktronics outdoor LED
scoreboards.
Figure 6: Power Terminal Block
To gain access to the driver enclosure, open the
access door or digit panel and remove the cover
from the enclosure. Refer to the component
locations drawings for the access location for your
scoreboard.
Connect power and signal cables at the appropriate
locations on the driver enclosure panel, shown in
Drawing A-293354 .
The conventional power termination panel has been eliminated from Daktronics
outdoor scoreboards; the power feeder circuit connects directly to a terminal block in
the driver enclosure, as shown in
Figure 6 above.
The terminal block is located in the lower right corner of the enclosure. Connect the
power wires as shown in the illustration. Refer to the driver engineering drawings
and the schematics listed at the beginning of this section for additional wiring details.
The schematics include a detailed illustration of the power termination.
Note: If a power receptacle is needed to operate the control console at the scoreboard
for troubleshooting, Daktronics recommends that an installation electrician provides
a 120 V outlet close to the disconnect box specifically for this purpose.
