Detail Text Description
A technical schematic diagram depicting a typical riser for site lighting power source. At the top, the diagram features supervisory control with several electrical components, including numbered wires and labeled components such as CR1, CR2, CR3, and others. There are connections leading to DDC – DI and various conduit lines represented by different line styles.
In the middle schematic, a contactor for control wiring diagram is provided, showing an arrangement of fusing, relays, contactors, and pilot lights.
Beneath this various technical notes labeled as NOTE 1, NOTE 2, and NOTE 3 provide instructions and specifications for installation, such as conduit sizing, circuit types, and power requirements. The diagram also includes references to site-specific components like a lighting contactor and panel board integration specifics.
The site lighting contactor is controlled by a local DDC circuit, or by photocell when DDC is not available.
