EARTHING kit SCHROFF 21100-448 for 4U COMPTEC chassis

EARTHING kit SCHROFF 21100-448 for 4U COMPTEC chassis provides the necessary grounding components for installation in 4U rack enclosures. The kit is designed to create reliable chassis-to-rack and chassis-to-earth connections, helping to equalize potential, reduce electromagnetic interference and protect mounted electronics in server and industrial applications. Parts are shaped and spaced to match mounting points on compatible 4U COMPTEC chassis, allowing straightforward mechanical and electrical integration.

Advantages

The kit supplies a complete set of conductive parts and fasteners that are matched to 4U COMPTEC mounting geometry, minimizing the need for modification. Materials and plating are selected for corrosion resistance and stable conductivity to ensure long-term grounding performance. Using the kit helps maintain predictable grounding paths, which can reduce electrical noise and improve system reliability when installed correctly in rack environments.

Suitable for

• Grounding 4U COMPTEC server or industrial chassis in 19" rack systems
• Providing chassis-to-rack and chassis-to-earth connections during equipment installation
• Reducing electromagnetic interference in sensitive electronics installations
• Retrofit or new-build rack installations that require standardized earthing points

Key specifications

• Compatibility: designed for 4U COMPTEC chassis mounting points
• Function: provides chassis grounding and earthing connections
• Materials: conductive metal components with corrosion-resistant plating
• Includes: mounting-compatible parts and fastening hardware for direct fitting
• Application environment: server racks, industrial enclosures, telecom cabinets

How to use

Position the earthing kit components at the designated grounding points on the 4U COMPTEC chassis and align them with the corresponding rack or earth connection. Secure the conductive parts with the supplied fasteners, ensuring tight mechanical contact between metal surfaces to minimize contact resistance. Connect the earth conductor to the building ground or rack earthing rail following applicable electrical and safety standards. Verify continuity and low resistance of the grounding path with appropriate test equipment after installation.

Recommendations

Install and verify the earthing kit during initial chassis mounting or maintenance windows. Use proper torque for fasteners to preserve contact integrity, and periodically inspect connections for corrosion or loosening in high-vibration or humid environments. Follow site-specific grounding practices and local electrical codes when routing and connecting earth conductors.
