how to install Vertiv VR Rack Accessory VRA Copper BUS Bar

Before beginning installation, power down equipment and follow your facility’s safety procedures. Verify that the rack space is clear and that the 42U Vertiv VR Rack is accessible for mounting the VRA6042 copper bus bar. Use the included hardware and ensure all connections are clean and free of debris to maximize electrical contact and longevity.

Step 1: Prepare the rack and bus bar. Inspect the copper bus bar for any shipping damage and confirm that mounting holes align with the VR Rack’s rail interface. Clean any dust or oxidation from contact points if needed to ensure a solid electrical connection.

Step 2: Align with mounting pattern. Position the copper bus bar so that its mounting holes line up with the standard 19" rack rails of the 42U Vertiv VR Rack. Carefully orient the bar to optimize grounding path continuity across the rack frame and power distribution components.

Step 3: Secure the bus bar. Use the supplied mounting hardware to fasten the copper bus bar to the rack rails. Tighten hardware to the manufacturer’s recommended torque to avoid loosening during equipment movement or thermal cycling.

Step 4: Connect grounding/grounding-strap points. Attach any designated grounding straps or connectors to the bus bar as specified by your data-center grounding plan. Ensure secure, clean contact between the bus bar and the grounding points on the rack chassis and power distribution units if applicable.

Step 5: Verify continuity and integrity. Perform a continuity check across the grounding path and inspect all fasteners for tightness. Confirm that the bus bar is firmly mounted, with no loose components, to maintain reliable performance under load.

Step 6: Power up and test. Restore power to the equipment and monitor grounding stability, thermal behavior, and any electrical noise indicators. If you notice irregularities, re-check connections and torque, then re-test until the system shows a clean, stable electrical profile.
