Connect power and signal cables at the appropriate
locations on the driver enclosure panel, shown in
Drawings A-284920 and A-284922 .
Electrical Installation
44
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 7 . 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
to the schematics listed at the beginning of this section for
additional wiring details. The schematics
include a
detailed illustration of the power
termination.
Figure 7: Power Terminal Block
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.
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 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.
Figure 8: Signal Surge Arrestor Card
Note: It is important that the shield wire is properly connected to
the shield terminal on the signal surge arrestor card. Figure 8
illustrates the signal surge arrestor card and connectors.
For signal cable, Daktronics recommends, as a minimum, single-
pair, shielded cable, 22 AWG (Daktronics part number W-1077).
Two-pair shielded cable (Daktronics part W-1614) is preferred.
Fiber Optic
Another common signal communication method is using fiber
optic cabling. A minimum cabling of multi-mode; 62.5/125 um;
and 2-core fiber cable is recommended. (Daktronics part number is
W-1242.) See
Figure 9 for the location of fiber connector on the
LED driver. (See Drawing A-288137 for the complete image of the
LED driver.)
