Installing 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.
To connect the system ground, you need the following tools and materials:
Note The grounding lug and the grounding lug screws are supplied as part of the accessory kit. The grounding
wire and the tools are not supplied as part of the accessory kit.
• Grounding lug—A two-hole standard 90-degree barrel lug. Supports up to 6 AWG wire.
• Grounding screws—Two M4 x 8 mm pan-head screws.
• Grounding wire—The grounding wire should be sized according to local and national installation
requirements. Depending on the power supply and system, a 12
AWG to 6 AWG copper conductor
is required for U.S. installations. We recommend that you use commercially available 6
AWG wire.
The length of the grounding wire depends on the proximity of the switch to proper grounding
facilities.
• No. 1 Phillips screwdriver.
• Wire-stripping tool to remove the insulation from the grounding wire.
• Crimping tool to crimp the grounding wire to the grounding lug.
