Electrical Installation
4-4
Connect the power wires as shown in the illustration. Refer 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 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.
It is important that the shield wire is properly connected to the shield
terminal on the signal surge arrestor card. Figure 6 illustrates the printed circuit
board and the terminal blocks.
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-1234) is preferred.
For additional information on signal connection, refer to the All Sport 5000 Series
control console operation manual,
ED-11976 .
