Daktronics BA-1518 Multi-Section Outdoor LED Scoreboard - Manual (Page 28)

22 Electrical Installation
1. On the upper section, open the appropriate access panel to locate the bundle of
interconnect cable coming from the driver.
Note: Additional panels may be opened for easier access when routing the cable.
2. Route the interconnect cable through the hole in the bottom of the upper cabinet
through the hole in the top of the lower cabinet, and plug it into the driver.
 If the lower section contains the master driver, the harness will connect to J42.
 If the lower section contains the slave driver, the harness will connect to P43.
3. With four-section scoreboards, be sure to also connect any plugs extending from the
right side of the left cabinets to the corresponding jacks on the left side of the right
cabinets.
Note: Similar connections exist between the upper and lower cabinets of multi-
section, single-driver scoreboards as well.
4.6 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.
