of the control enclosure and terminated at TBL1. Refer to
Detail “A” of DWG-5115728 .
A voltage surge protector (part # A-1129) is provided
(shipped inside the control enclosure) for additional
protection at the main breaker panel. Refer to Figure 12 and
Detail “B” of DWG-5115728 .
Signal IN
A minimum of 2-core, multimode 50-micron fiber optic cable must be run in conduit from
the fiber conversion box location to the sound cabinet control enclosure (FPP2). Refer
to Detail “D” of DWG-5115728 . If included with a Daktronics scoreboard or display, the
sound system may share a fiber optic cable run, requiring additional cores.

polarity when wiring them. Confirm the proper connections by referring to Detail “A”
of DWG-5115728 .
Note: To prevent the possibility of short circuits, strip each wire 8 mm and tighten the
screw connection terminal to a minimum torque of 0.6 Nm.
