4 Electrical Installation
This section explains the steps necessary to make final electrical connections to the
display from the primary power source. For display-specific power requirements, refer to
the Shop Drawing or label on the rear of the display. Follow all installation guidelines.
Warnings and Disclaimers
• Ensure that all electrical work meets or exceeds all local or national electrical codes.
• Provide the required power to the display as listed on the product labels,
specifications, or site-specific riser drawings. The conductor size may vary based on
the length of the power run.
• Consider implementing a separate circuit for the display using an isolation
transformer or dedicated transformer.
• Daktronics assumes no liability for any issues caused by line voltage fluctuations or
other improper power conditions.
Important Notes
• Qualified personnel must perform electrical installations to prevent injury to personnel
and damage to the equipment.
• Daktronics engineering staff must approve any changes made to the display. Before
altering the display, submit detailed drawings for the proposed modifications to the
Daktronics engineering staff for evaluation and approval, or the warranty will be void.
• Improper installation could result in serious damage to the equipment and could be
hazardous to personnel.
• Size conductors of circuits that deliver power to the display according to national
and local electrical codes so the power distribution system delivers full-load power to
the display while maintaining a voltage within 5% of the utility nominal voltage.
Power Requirements
• Install the display according to all applicable local and national electrical codes. This
includes proper grounding and bonding of the display.
• Do not connect the display to any voltage other than that listed on the Daktronics
product label.
• Displays use single-phase power. Proper power installation is imperative for display
operation.
Main Disconnect
Daktronics requires using a power disconnect switch with the display. A disconnect allows
all ungrounded conductors to be disconnected near the point of power connection.
Locate the disconnecting means either in a direct line of sight from the display or so it
can be locked in the open position. This ensures that power is not reconnected while
service personnel work on the display.
