Signal cable is routed to the signal termination enclosure. Ground the enclosure to an
isolated earth ground connector (when required).

Power Requirements
Install this display in accordance with any applicable local and national electrical codes.
This includes proper grounding and bonding of the display.
Do not connect the displays to any voltage other than that listed on the Daktronics
product label.
Note:
Conductors of circuits delivering power to a Daktronics display shall be sized
in accordance with local and national electrical codes so that the power
distribution system is capable of delivering full load power to the display while
maintaining a voltage within five percent of the nominal utility voltage.
Displays use single-phase power. Proper power installation is imperative for display
operation. Daktronics requires using a power disconnect switch with the display. Use a
disconnect so that all ungrounded conductors can be disconnected near the point of
power connection.
The disconnecting means must be either located in a direct line of sight from the display
or capable of being locked in the open position. This ensures that power will not be
reconnected while service personnel work on the display.
Grounding
All components of a display system—including but not limited to displays, 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 display system may void the warranty, disrupt
operation, damage equipment, and cause bodily harm or death.
Power Connection
Power is most often terminated externally to the J-box on displays. However, larger
displays require power to be terminated internally in the Power Termination Panel.
