Connect power and signal cables at the appropriate locations on the driver enclosure
panel, shown in
Drawing A-178197 .
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 9 . 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
drawing 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: Driver enclosures in some earlier Daktronics
scoreboards included a 120 V power receptacle. There is no 120 V receptacle in
Generation III displays. If you want power to operate the control console at the
scoreboard for troubleshooting, Daktronics recommends that you have the
installation electrician provide a 120 V outlet close to the disconnect box specifically
for this purpose.
Route signal cabling to the signal surge arrestor card in the upper left corner of the
driver enclosure. The connections are labeled to permit easy installation. At the
Signal In terminal block on the printed circuit board (PCB), connect the red signal
wire to the positive terminal, the black to the negative terminal, and the shield
(silver) wire to the shield terminal.
Note: It is important that the shield wire is properly connected to the shield terminal
on the signal surge arrestor card. Figure 10 illustrates the signal surge arrestor card
and connections.
For signal cable, Daktronics recommends, as a minimum, single-pair, shielded cable,
22 AWG (Daktronics part number W-1077). Two-pair shielded cable (Daktronics
