Vertiv VR Rack Accessory VRA6043: Copper BUS Bar for 48U Racks

The Vertiv™ VR Rack Accessory VRA6043 Copper BUS Bar is a purpose-built solution designed to deliver reliable grounding, effective equipment bonding, and streamlined thermal management in modern data centers. Built to integrate seamlessly with Vertiv VR Rack systems, this copper bus bar establishes a low-impedance common ground across the entire 48U rack, helping to minimize electrical noise, reduce potential differences between devices, and enhance overall system safety. In dense equipment environments where consistent grounding and efficient heat transfer are critical, the VRA6043 stands out as a robust, long-lasting addition that supports uptime, reliability, and efficient cooling performance.

• Common ground and robust bonding: The copper bus bar provides a low-resistance, continuous bonding path across all mounted devices in the VR rack. By creating a shared ground, it minimizes ground loops and potential differences between equipment, which can lead to reduced electromagnetic interference (EMI) and improved signal integrity for servers, storage, and networking gear.
• Designed for 48U Vertiv VR Rack configurations: Specifically engineered to fit 48U VR Rack footprints, the VRA6043 ensures a secure, precise installation that aligns with Vertiv’s mounting standards. This compatibility simplifies deployment in data centers that rely on Vertiv VR Rack infrastructure, enabling quicker onboarding and consistent performance across cabinets.
• Enhanced heat dissipation through conductive bonding: Copper’s excellent thermal conductivity allows the VRA6043 to participate in heat distribution within the rack. By providing an efficient conduction path, it helps spread heat away from critical components and toward the rack’s cooling system, complementing the built-in thermal management of the cabinet.
• Durable, corrosion-resistant construction: Crafted from high-quality copper, the BUS Bar resists corrosion and maintains reliable conductivity in challenging data center environments. A protective finish further extends lifetime, reducing maintenance needs and ensuring stable performance over time.
• Easy integration and maintenance-friendly: The VRA6043 is designed for straightforward integration with existing VR Rack hardware. Its simple installation procedure minimizes downtime, while the durable build reduces the frequency of servicing. Regular inspections of grounding connections maintain optimal bonding integrity for years to come.

how to install Vertiv VR Rack Accessory

• Prepare the rack: Before installation, power down equipment as applicable and verify that the rack enclosure is properly grounded. Clear mounting areas to ensure a clean, unobstructed bonding plane where the copper BUS Bar will be installed.
• Verify compatibility and orientation: Align the VRA6043 with the rack’s mounting holes or attachment points designed for this accessory. Confirm that the bus bar will span the intended bonding plane to maximize ground continuity across all devices within the 48U cabinet.
• Secure the bus bar: Use the supplied hardware to fasten the copper BUS Bar to the rack structure. Tighten hardware to manufacturer-recommended torque without overtightening, ensuring a secure, vibration-resistant connection that maintains low electrical resistance over time.
• Connect equipment grounding conductors: Attach grounding/earthing conductors from devices within the rack to the bus bar. Ensure all connections are clean, tight, and free of oxidation to preserve a solid bonding path and minimize contact resistance.
• Test the bonding path and cooling synergy: After installation, perform a continuity check to verify a continuous ground path across the cabinet. If possible, conduct a basic thermal test to observe how the conductive bonding interacts with the rack’s cooling strategy and ensure there are no hotspots around critical components.
