Page 24: Power
Displays must be grounded according to the provisions outlined in Article 250 of the ® National Electrical Code . Daktronics requires a resistance to ground of 10 ohms or less. The display system must be connected to earth-ground. Proper grounding is necessary for reliable equipment operation. -
Page 25: Power Installation
Article 250 of the National Electric Code may be used. Daktronics requires that the resistance to ground be 10 ohms or less. If the resistance to ground in higher than 10 ohms it will be necessary to install additional grounding electrodes to reduce the resistance. -
Page 26: Power Connection
Installation with Only a Neutral Conductor Provided Installations where no grounding conductor is provided must comply with article 250-32 of the National Electrical Code. If the installation in question meets all of the requirements of article 250-32, the following guidelines must be observed: •... -
Page 27: Main Disconnect
Main Disconnect The National Electrical Code requires the use of a lockable power disconnect near the display.
