Connection
Power and signal cables are routed into the display from the rear via separate conduits.
All power and signal wiring terminates at the primary driver enclosure. Note that systems
with radio control typically only require signal wiring for backup purposes.
Refer to the component location drawings attached to the product specification sheets
listed in Appendix A for precise power/signal termination location for each model. For
modular and hybrid football scoreboard component locations, refer to the service
manual listed in Troubleshooting (p�2) .
1� Look for a warning label similar to Figure 18
to locate the access panel to the driver
enclosure.
2� Remove the screws or loosen the latches to
open the access door panel.
3� Remove the metal cover of the driver
enclosure by lifting it up, then back and down to expose the driver components.
4� Connect the power wires coming through the rear of the display to the power
terminal blocks, as shown in Figure 19 .
Some modular scoreboard sections do not receive power via terminal block. Instead, an
interconnect harness routes from the nearest scoreboard section. Refer to Power/Signal
Connections Between Sections (p�22) .
Note: If a power receptacle is needed to operate the control console at the display
for troubleshooting, an installation electrician must provide an outlet close to the
disconnect box specifically for this purpose.
