Each uses a 120/240VAC single-phase or 120/208 three-phase power source. Do not connect the displays to any voltage other than what is listed on the Daktronics product label. Proper power installation is imperative for proper display operation. The following sub-sections give details of display power installation. -
Page 29: Grounding
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 is higher than 10 ohms, it will be necessary to install additional grounding electrodes to reduce the resistance. -
Page 30: Main Disconnect
Power Installation There are two considerations for power installation: installation with ground and neutral conductors provided and installation with only a neutral conductor provided. For these displays, installation with ground and neutral conductors provided is used. Installation with Ground and Neutral Conducto s Provided For this type of installation, the power cable must contain an isolated earth-ground conductor. -
