3.6 Lightning Protection
The use of a disconnect near the scoreboard to completely cut all current-carrying lines
significantly protects the circuits against lightning damage. In order for this system to
provide protection, the power must be disconnected when the scoreboard is not in use.
The control console should also be disconnected from power and from the signal junction box
when the system is not in use. The same surges that may damage the scoreboard’s driver can
also damage the console’s circuitry.
