Grounding kit SCHROFF for telescopic shelf 21120189

Grounding kit SCHROFF for telescopic shelf 21120189 is an accessory designed to provide a reliable earth connection for rack-mounted sliding shelves and the equipment installed on them. The kit is intended to be integrated during installation or maintenance of server and electronics cabinets to reduce the risk of electrostatic discharge and to help ensure safe, stable operation of connected devices. It is compatible with telescopic shelf assemblies that accept external grounding accessories and supports standard cabinet earthing practices.

Advantages

The grounding kit offers a straightforward mechanical and electrical connection between the telescopic shelf and the rack earth, ensuring consistent contact even when the shelf is extended or retracted. Constructed from conductive materials suited for grounding applications, the kit is built to withstand repeated movement and provide low-resistance paths to ground. Installation requires no modification to installed equipment and can be performed as part of routine cabinet setup or service procedures, helping to maintain EMC and safety compliance.

Suitable for

• Telecentric and telescopic sliding shelves in server racks and cabinets
• Server, network and storage equipment installed on sliding shelves
• Data centers, telecom closets and equipment rooms requiring reliable earthing
• Maintenance operations where shelf removal or movement may interrupt grounding

Key specifications

• Function: Provides electrical grounding/earthing for telescopic shelves and mounted equipment
• Material: Conductive metal components with corrosion-resistant finish for reliable contact
• Connection type: Mechanical fastening to shelf and rack frame with conductive interface
• Movement compatibility: Maintains electrical contact during shelf extension and retraction
• Operating environment: Designed for use inside standard equipment racks and cabinets in controlled data center or telecommunications environments

How to use

Mount the grounding kit to the telescopic shelf and the rack frame following the manufacturer's installation points and torque recommendations. Ensure mating surfaces are clean and free of paint or debris where conductive contact is required. Attach the grounding conductor to the rack earth point using the provided fasteners or an appropriate earth stud, and verify continuity with a multimeter to confirm a low-resistance path to ground. Re-check connections after any shelf movement or equipment changes.

Usage recommendations

Verify compatibility with the specific telescopic shelf model before installation and follow local earthing and safety regulations. Periodically inspect the grounding connection for corrosion or loosened fasteners and test continuity during maintenance intervals to ensure persistent low-resistance grounding.
