Siemens 6SL31621AF000AA1 Shield Connection Clamp

Product Description

The SIEMENS 6SL31621AF000AA1 is a shield connection clamp designed to establish a reliable EMC-compliant shielding connection on drive system cables. It provides a low-impedance bond between the cable shield and the drive chassis, reducing electromagnetic interference in variable frequency drive (VFD) and servo drive installations. The clamp is a hardware accessory used by licensed electricians and drive systems technicians during the commissioning or service of Siemens SINAMICS and similar drive platforms. At 0.882 pounds, it is a compact component that mounts directly to the drive cabinet rail or shield bus.

This shield connection clamp is used in industrial and commercial electrical installations where EMC compliance is required for motor cable shielding. Typical applications include variable speed drive panels, servo control cabinets, and motion control enclosures where proper cable shielding termination is critical to system performance and regulatory compliance. It is installed during initial drive commissioning or when retrofitting existing cable management assemblies.

Key Features

• Provides low-impedance EMC shielding connection for drive system cables
• Designed for use with Siemens SINAMICS drive series shield bus systems
• Compact, lightweight construction at 0.882 pounds
• Supports proper cable shield termination to reduce radiated and conducted interference
• Mounts to standard drive cabinet rail or shield connection bar

Compatibility

Designed as an OEM-style accessory for Siemens drive system installations requiring EMC-compliant cable shield termination. Refer to the specific drive system documentation to confirm fitment before installation.

Installation Notes

Installation should be performed by a licensed electrician or qualified drive systems technician familiar with NEC requirements and EMC wiring practices. De-energize and lock out the drive system completely before handling any internal wiring or shield connection hardware. Ensure the cable shield is trimmed and prepared per the drive manufacturer guidelines before securing the clamp. Do not overtighten the clamp onto the shield braid, as this can damage the cable.
