Overview

The ABB SRG2-1 Signal Reference Grid Copper Connector (SKU: SRG2-1) is a high-conductivity wrought copper compression connector designed for secure grounding and bonding in signal reference grid applications. This connector accommodates wire ranges from #2 AWG to #1 AWG, providing a reliable termination point for critical grounding conductors in industrial and commercial installations. Key specifications include compatibility with pedestal posts up to 1 inch square or 1 to 1.25 inches round. The SRG2-1 features a plain finish and is installed using T&B Method Hex Compression with hydraulic tools TBM15 or TBM14M and dies 15527, 15528, or 15530, depending on cable size. Installation requires a torque of 275 in-lbs for the provided nut and bolt assembly. The connector's design supports single or dual crimp configurations, with the initial crimp positioned closest to the connector body when multiple crimps are required. For inspection, embossed die numbers on hex flats indicate the installing die used. All four bolt holes must be secured for proper installation. Applications include telecommunications infrastructure, power distribution systems, and industrial automation where dependable grounding is essential. The SRG2-1 ensures minimal signal interference and long-term corrosion resistance, making it suitable for demanding environments. Installation must comply with national and local electrical codes, and should be performed by a qualified electrician. Ordering note: Die selection depends on cable size—refer to Table 1 in the installation instructions for specific die codes.

How to Install the Signal Reference Grid Connector

This guide provides step-by-step instructions for installing the Signal Reference Grid Connector on a raised floor grounding system.

Estimated time: 30m

Tools needed:

Screwdriver, Wire brush, Crimping tool, Multimeter

Supplies needed:

Mounting screws, Nut and bolt, Connector body

  1. Secure the connector

    Locate the connector on the pedestal post and secure it into position by tightening the provided nut and bolt to 275 in-lbs.

  2. Prepare the cable

    Determine the areas along the length of the cable for terminations. Clean the cable of all visible dirt with a rough cloth or brush and ensure a bright copper finish by using a wire brush.

  3. Crimp the connector

    Match the proper die code number for the connector and cable size. Place the cable in the connector's cable bore, position it on one of the die halves, and perform the initial crimp closest to the connector body. If a second crimp is required, perform it afterward.
