Connecting the System Ground
The system (NEBS) ground provides additional grounding for EMI shielding requirements and is
intended to satisfy the Telcordia Technologies NEBS requirements for supplemental bonding and
grounding connections.
Note The ground lug and the ground lug screws are supplied as part of the accessory kit. The ground wire and
the required tools are not supplied as part of the accessory kit.
To assemble and connect the system ground, you need the following tools and materials:
• Ground lug—A two-hole standard 90-degree barrel lug. Supports up to 6 AWG wire.
• Ground screws—Two M4 x 8-mm pan-head screws.
• Ground wire—The ground wire should be sized according to local and national installation
requirements. Commercially available 12 AWG to 6 AWG wire is recommended. The length of the
ground wire depends on the proximity of the switch to proper grounding facilities.
• Number 1 Phillips screwdriver.
• Wire-stripping tool to remove the insulation from the ground wire.
• Crimping tool to crimp the ground wire to the ground lug.
To assemble the ground lug and cable and attach them to the ground pad (see Figure 7), follow these
steps:
Step 1 Use a wire-stripping tool to remove approximately 0.75 inch (19 mm) of the covering from the end of
the ground wire.
Step 2 Insert the stripped end of the ground wire into the open end of the ground lug and crimp the barrel of the
ground lug. Verify that the ground wire is secure in the ground lug.
