## Summary description

Rittal DK 7544.000 is a vertical grounding busbar designed for VX and VX IT enclosures. Supplied as a single multicolour unit, it provides a dedicated earth connection point along the cabinet interior. Suitable for equipping server racks and industrial control cabinets where a reliable vertical earthing conductor is required for safety and EMC management.

## Long description

Rittal DK 7544.000 is a vertical grounding busbar designed for VX and VX IT enclosures, length 1145 mm. Supplied as a single multicolour unit, the busbar provides a dedicated earth connection point inside server racks and industrial control cabinets. The product supports star earthing of cable clamp straps in patch panels and features fully adjustable earth terminals. The rail has an approximate current carrying capacity of 200 A, enabling reliable protective and equipotential bonding for enclosure installations where a vertical earthing conductor is required for safety and EMC management.
Advantages
The grounding busbar offers a compact vertical design that integrates with VX and VX IT cabinet interiors without occupying horizontal mounting space. Fully adjustable earth terminals allow flexible connection of multiple equipotential bonding conductors and cable straps. The multicolour finish makes identification and orderly wiring straightforward. With an approximate 200 A current carrying capacity, the rail supports typical rack and control-cabinet grounding needs while facilitating star earthing arrangements for improved EMC and safety performance.
Suitable for (tasks / use cases)
 Vertical grounding inside Rittal VX and VX IT server racks and network cabinets
 Equipotential bonding and star earthing of patch panel cable clamp straps
 Grounding multiple modules and equipment inside industrial control cabinets
 Retrofitting or upgrading earthing points in existing enclosures
When it may not be suitable
The DK 7544.000 busbar is designed specifically for VX and VX IT enclosures; it may not fit or mount correctly in cabinets from other manufacturers or different Rittal series without compatible mounting provisions. It is intended as an enclosure grounding conductor and is not a substitute for larger building earthing conductors or main earthing systems where higher continuous current carrying capacity or different mechanical formats are required.
Key specifications
 Form factor: vertical busbar for inside-cabinet mounting
 Compatible enclosures: Rittal VX and VX IT series
 Length: 1145 mm
 Supply configuration: single multicolour unit with adjustable earth terminals
 Functionality: supports star earthing of cable clamp straps and equipotential bonding

How to use
Mount the vertical grounding busbar onto the designated interior profile or mounting points of a VX or VX IT enclosure, following Rittal cabinet installation guidelines. Connect the enclosure main earth conductor to the busbar, then attach individual equipment and cable-strapping earth conductors to the adjustable earth terminals to implement a star earthing layout. Ensure mechanical fastening is secure and electrical terminations are tightened to the torque values specified by local electrical standards. Verify continuity and resistance of the grounding connections as part of commissioning and periodic maintenance.
What to consider before purchase
 Confirm cabinet compatibility with Rittal VX or VX IT mounting profiles and available interior space for a 1145 mm vertical rail
 Check that the approximate 200 A current carrying capacity meets the earthing requirements of your installation
 Plan the number and type of earth conductors and terminal adapters needed for your equipment and cable clamp straps
 Verify local electrical codes for grounding and bonding practices to ensure compliance
Usage recommendations
For reliable EMC and safety performance, use the busbar as the central enclosure earth point and arrange individual equipment earths in a star configuration. Inspect terminations after installation and include the busbar in periodic grounding system checks to ensure low-resistance continuity.
