Attachment 4 Photos.pdf

This file is Attachment 4 Photos, a visual appendix containing four photographs of industrial control systems and electrical equipment installations.

The photographs depict various configurations of control panels and system components: Page 1 shows an open blue metal enclosure containing circuit boards, relays, transformers, and wiring assemblies viewed from above. Page 2 displays a blue dual-unit cabinet mounted on a wall, with ventilation grilles and warning labels visible on each section. Page 3 shows an open gray metal cabinet containing a green circuit board with multiple connectors, colored wiring harnesses, power supplies, and associated electrical components. Page 4 presents a gray two-tier wall-mounted enclosure labeled "TACO" and "ThyssenKrupp Elevator" with ventilation louvers and a yellow warning label. These images appear to document existing equipment configurations, possible system upgrades, or reference installations relevant to a contract requirement, though no specific technical specifications or performance requirements are detailed in the photographs themselves.
