18 Electrical Installation
Installation with Ground and Neutral Conductors Provided
For this type of installation, the power circuit must contain an isolated earth-ground
conductor. In this circumstance, do not connect neutral to ground at the disconnect or at the
display as this would violate electrical codes and void the warranty. Use a disconnect so that
all ungrounded lines can be disconnected. The National Electrical Code requires the use of a
lockable power disconnect within sight of or at the display.
Installation with Only a Neutral Conductor Provided
Installations where no grounding conductor is provided must comply with Article 250-32 of
the National Electrical Code. If the installation in question meets all of the requirements of
Article 250-32, the following guidelines must be observed:
 Connect the grounding electrode cable at the local disconnect, never at the display
driver/power enclosure.
 Use a disconnect that opens all of the ungrounded phase conductors.
Single-Court Power Connection
Both power and signal cables are routed into the scoreboard from the rear through two
plastic plugs for conduit connection. All power and signal wiring terminates at the master
driver enclosure. Note that systems with radio control do not require external signal wiring.
Look for a warning label similar to Figure 17 to locate the
front access panel to the driver enclosure. 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. Remove
the screws or loosen the latches to open the access door panel.
Remove the metal cover of the driver enclosure to expose the driver components (Figure 18).
Connect the appropriate wires coming through the rear of the scoreboard to the power
terminal block, as shown in Figure 18.
