9 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 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

10 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. Remove the bottom two modules from the second column on the left side of the display with a 1 / 8 hex head wrench. A component layout is shown in Figure 7.

Customers who follow the program guidelines explained below will receive this service.

Fill out and attach the enclosed UPS shipping document. c. Ship the part to Daktronics. 3. A charge will be made for the replacement part immediately, unless a qualifying service agreement is in place. In most circumstances, the replacement part will be invoiced at the time it is shipped. If the failed part or replacement part is not returned to Daktronics within 3 weeks of the ship date, Daktronics will assume that the customer is purchasing the replacement part and will send an invoice for the value of the new sale part. If the part or parts are returned within 2 weeks of the second invoice date, Daktronics will credit the customer for the second invoice. If after 2 weeks Daktronics has still not received the parts back, the customer must pay the second invoice and will not be credited for the return of the failed part. Daktronics reserves the right to refuse parts that have been damaged due to acts of nature or causes other than normal wear and tear. Daktronics Exchange and Repair & Return Programs 32
