Electrical

Power Termination

Junction boxes ship separately from the display and are supplied for landing power. Refer to the contract-specific Riser Diagram for junction box locations. Field power must be terminated in each junction box. The connections from the breaker panel to each junction box must be performed by a licensed electrician. Refer to Figure 1.
Figure 1: Power Entrance

The junction box can power multiple sections on a three-phase 20 A circuit. Power is daisy-chained internally with factory-supplied harnessing. Refer to the contract-specific Riser Diagram for field power locations within the display.

Signal Interconnection

1. Identify the appropriate router based on the display’s pixel pitch:
   • 3.9 mm & 5.9 mm – Mini ProLink router (mini PLR). Refer to Figure 2.
     Figure 2: Mini PLR
     
   • 10 mm – ProLink router (PLR). Refer for Figure 3.
     Figure 3: PLR
     
2. Use the supplied hardware to place the Mini PLR(s) or PLRs at the locations specified on DWG-5487197 and the contract-specific Signal Interconnect Drawing and Riser Diagram. Refer to Figure 4.
   Figure 4: Mount PLR
   
3. Route the field fiber cable (from the control location) through the signal entrance, then terminate. Refer to Figure 5.
   Figure 5: Fiber Cable
   
4. Use the supplied power cable (Daktronics part number 0A-2453-7005) to connect the Mini PLR or PLR to the power supply fan connector.
   Refer to Figure 6 and Figure 7.

5. Connect the field-terminated fiber cable to Fiber Port A on the first Mini PLR or PLR in the system (typically the upper-right corner of the first cabinet when viewed from the rear). Refer to Figure 6 and Figure 7.
6. Route the supplied fiber cables from Fiber Port B on the first Mini PLR or PLR to Fiber Port A on the next Mini PLR or PLR. Refer to Figure 6 and Figure 7. Depending on the number of Mini PLRs or PLRs, this process is continued until Fiber Port A on the final Mini PLR or PLR in the chain is connected. Refer to the contract-specific Signal Interconnect Drawing.
7. Route the supplied SATA cable from SATA Port A on the PLR to SATA Port A on the first module.
   SATA connection between cabinets may be required depending on the overall display size.
   Use the supplied SATA cables to connect the cabinets. Refer to Figure 8. Cabinet-to-cabinet SATA connections are made via cables secured to the top of each module column. Refer to the Signal Interconnect Drawing for data routing information.
