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 display's back. Electrical Installation Preparation Follow all installation guidelines Route power to the display through a disconnect switch Provide the required power per display requirements Follow all local and national electrical codes Do not wire the display to a timer or light sensor, ensuring the eccb display has power at all times Do not connect the display to any voltage other than that listed on the product label Do not connect the neutral to the ground at the disconnect or the display Electrical Requirements Do not connect displays to any voltage other than that listed on the display product label. Galaxy eccb displays have a voltage input of 100-240 VAC and a frequency input of 50/60 Hz. Galaxy eccb displays do not operate on 277 VAC. Connecting 277 VAC may damage internal components and will void the display's warranty. A dedicated circuit can be shared among all components of the sign structure (including Galaxy eccb displays and fluorescent lighting), but only if the circuit is not controlled by timers or external light sensors. If a circuit is controlled by these devices, either assign the eccb to a separate circuit so it has power at all times or disconnect the timers or external light sensors. The eccb display cannot share a circuit with external electrical devices such as air compressors or island lighting. A dedicated circuit is defined as one hot, one neutral, and one ground wire. Maximum amperage will vary with the number and size of Galaxy eccb displays connected. Follow all local and national electrical codes during electrical installation. Note: Displays must be fed by a branch circuit no larger than 20A. Failure to meet wiring and over-current protection device requirements may violate local and national electrical codes and will void the display warranty. Note: Size circuits according to local and national codes so the power distribution system delivers full-load power to the display while maintaining a voltage within 5 percent of the nominal voltage. Main Disconnect Daktronics requires installation of a power disconnect switch with the display so all ungrounded conductors can be disconnected near the point of power connection. Electrical Installation 5
Electrical Installation Only qualified individuals should perform power routing and termination to the display. It is the electrical contractor's responsibility to ensure that all electrical work meets or exceeds local and national codes. Improper installation could result in serious damage to the equipment and could be hazardous to personnel. Verify the existing disconnect switch (circuit breaker) has a rating that will handle the Galaxy eccb display and the remaining sign load. If the rating of the branch circuit and or disconnect switch is exceeded then a new disconnect switch and possibly additional branch circuits may be required. 1. Disconnect power to the display. 2.
