Grounding set SCHROFF 21100-490 — earthing kit for electronic racks and enclosures, 1 set

Grounding set SCHROFF 21100-490 is a single-set earthing kit designed to provide a dependable equipotential connection between electronic racks, enclosures and the building earth. Supplied as a complete kit, it is intended for installation in server racks, telecommunication cabinets and industrial enclosures to reduce electrical noise, prevent potential differences between chassis and protect equipment and personnel from stray voltages.

Advantages

The kit offers a compact, ready-to-install solution that simplifies grounding across multiple chassis and metallic structures. It is engineered for reliable conductivity and mechanical durability, enabling consistent earthing contact under typical rack and enclosure mounting conditions. By establishing a common reference potential, the set contributes to reduced electromagnetic interference and improved safety without requiring extensive site modification.

Suitable for

• Server racks and data center cabinets
• Telecommunication and network enclosures
• Industrial control cabinets and switchgear
• Retrofit grounding of existing equipment racks

Key specifications

• Purpose: Establish equipotential bonding between chassis and building earth
• Contents: Complete single-set earthing components for one installation
• Material characteristics: Conductive materials designed for low-resistance connection and mechanical robustness
• Compatibility: Suitable for standard electronic racks and metal enclosures used in IT, telecom and industrial environments
• Mounting: Components intended for fixed attachment to rack or enclosure chassis

How to use

Install the grounding set by attaching the provided conductive elements to the rack or enclosure chassis and connecting the kit’s bonding conductor to the building earth or designated earthing point. Ensure all contact surfaces are clean and free of paint, corrosion or other insulating coatings to achieve low-resistance connections. Tighten fasteners to the specified torque where applicable and route the bonding conductor to avoid sharp edges or moving parts.

Usage recommendations

Verify local grounding regulations and site earthing practices prior to installation. Use appropriate personal protective equipment and de-energize circuits when making connections. Periodically inspect grounding connections for corrosion, looseness or damage and maintain good mechanical and electrical contact to ensure ongoing safety and noise reduction.
