Electrical Installation

Signal IN
A minimum of 2-core, multimode 50-micron fiber optic cable must be run in conduit
from the fiber conversion box location and terminated in a fiber splice box near the
sound cabinet. Fiber patch cables (part # W-1512) will then run in conduit to the control
enclosure media converter (FCC2). Refer to Detail “C” and Detail “E” of DWG-984140 .
If there is no fiber splice box, the fiber is terminated directly to the media converter. If
included with a Daktronics scoreboard or display, the sound system may share a fiber
optic cable run, requiring additional cores.
For the analog backup signal, 1 pair, 22 AWG cable (part # W-1615) must also be run in
conduit from the fiber conversion box location to the sound cabinet control enclosure
(TRX1). Refer to Detail “E” of DWG-984140 . The analog backup cable may pass through,
but not terminate in, a fiber splice box.
Grounding
All components of an audio system – including but not limited to control equipment,
and connected peripheral equipment – must be electrically grounded. Only qualified
individuals may perform electrical work, including verification of ground resistance.
Daktronics is not responsible for improper grounding or damage incurred as a result of
improper grounding.
Grounding methods must meet the provisions of all applicable local and national codes.
Inspect and verify all grounding methods meet the provisions of all applicable local and
national codes.
Proper grounding is necessary for reliable equipment operation and general electrical
safety. Failure to properly ground the sound system may void the warranty, disrupt
operation, damage equipment, and cause bodily harm or death.
Lightning Protection
The use of a disconnect near the system to completely cut all current-carrying lines
significantly protects the circuits against lightning damage. In order for this device to
provide protection, the power must be disconnected when the system is not in use.

IMPORTANT NOTES:
• The fiber box shall not be exposed to dripping or splashing, and no objects filled with
liquid shall be placed on the fiber box.
• The fiber box consists of Class 1 construction and shall be connected to a mains
socket outlet with a protective earth-ground connection.
• The fiber box utilizes a power cord with wiring inlet as a means for disconnection from
power. This means of disconnection shall remain readily operable in all cases.
Refer to Figure 12 for external fiber conversion box connections and Figure 13 for internal
connections and component locations.
Refer to Detail “A” in
DWG-984140 for analog backup connection and Detail “B” for fiber
connection. DWG-1095894 provides a detailed wiring schematic.
