Rack accessory Rittal 7545.000 vertical grounding bar for VX and VX IT racks

The Rittal 7545.000 vertical grounding bar is a dedicated rack accessory developed for use with Rittal VX and VX IT server and network racks. It provides a continuous vertical earthing path inside the enclosure, allowing reliable equipotential bonding of rack frames, subracks, cable management parts and mounted components. The grounding bar supports compliance with electrical safety practices in data centres, server rooms and network cabinets by offering a fixed, accessible connection point for protective conductors and bonding straps.

Advantages

The vertical grounding bar is constructed to integrate with VX and VX IT racks, offering a durable metal conductor that spans the rack height for consistent potential equalization. Its form factor minimises interference with mounted equipment and cable routing while supplying multiple attachment points for grounding conductors. This accessory simplifies installation of protective earthing, reduces the need for ad hoc bonding solutions and helps maintain a tidy internal rack layout.

Suitable for

• Establishing equipotential bonding in server racks and network cabinets
• Connecting protective earth conductors for rack-mounted equipment and PDUs
• Data centres, server rooms and network closets using Rittal VX or VX IT enclosures
• Retrofit grounding in existing racks where a dedicated conductor path is required

When it may not be suitable

This vertical grounding bar is specifically designed for compatibility with Rittal VX and VX IT rack systems. It may not fit non-Rittal enclosures or racks with different mounting geometries. If a full-cabinet equipotential bonding solution is already present or if local regulations require alternative earthing arrangements, this single-bar accessory alone may not fulfil all compliance requirements.

Key specifications

• Form factor: vertical grounding bar sized for full rack height
• Material: conductive metal suitable for protective earthing
• Mounting: designed to attach to internal rack mounting points of VX and VX IT enclosures
• Attachment points: multiple grounding connection locations along the bar
• Application environment: indoor use in data centres, server rooms and network cabinets

How to use

Mount the vertical grounding bar inside the VX or VX IT rack following the rack manufacturer’s mounting guidance. Secure the bar to the internal frame at the specified mounting positions, then attach protective earth conductors or bonding straps to the provided connection points. Ensure all connections are tightened to the recommended torque and that conductor cross-sections meet local electrical codes. Verify continuity between the bar and the building protective earth before energising equipment.

What to consider before purchase

• Confirm compatibility with Rittal VX or VX IT rack models and internal mounting layout
• Check required grounding conductor size and local earthing regulations
• Ensure sufficient clearance for equipment and cable routing after installation
• Plan for connection to the building protective earth or a central bonding point

Usage recommendations

Use the grounding bar as part of a complete equipotential bonding strategy: connect rack frames, PDUs and cable management metal parts to the bar, then link the bar to the building protective earth using appropriately sized conductors and approved terminations. Regularly inspect connections for tightness and corrosion to maintain electrical continuity and safety.
