Establishing System Ground
Before you begin
Warning
Before performing any of the following procedures, ensure that power is removed from the DC circuit.
Statement 1003
Warning Use copper conductors only. Statement 1025
Warning When stranded wiring is required, use approved wiring terminations, such as closed-loop or spade-type with
upturned lugs. These terminations should be the appropriate size for the wires and should clamp both the
insulation and conductor. Statement 1002
Warning When installing or replacing the unit, the ground connection must always be made first and disconnected last.
Statement 1046
To connect the system ground, you require the following tools and materials:
• Grounding lug—A two-hole grounding lug, which supports up to 6 AWG size. Supplied as part of the
standard accessory kit.
• Grounding screws—Two M4 x 8 mm (metric) pan-head screws. Supplied as part of the standard accessory
kit.
• Grounding wire—The grounding wire should be sized according to local and national installation
requirements. Depending on the power supply and system, a 12 to 6 AWG copper conductor is required
for U.S. installations. Commercially available 6-AWG wire is recommended. The length of the grounding
wire depends on the proximity of the switch to proper grounding facilities.
• No. 1 Phillips screwdriver.
• Crimping tool to crimp the grounding wire to the grounding lug.
• Wire-stripping tool to remove the insulation from the grounding wire.
Procedure
Step 1
Use a wire-stripping tool to remove approximately 0.75 inches (19 mm) of the covering from the end of the
grounding wire.
Step 2
Insert the stripped end of the grounding wire into the open end of the grounding lug.
Step 3 Crimp the grounding wire in the barrel of the grounding lug. Verify that the ground wire is securely attached
to the ground lug.
Step 4 Secure the grounding lug to the system ground connector with two M4 screws. Ensure that the grounding lug
and the grounding wire do not interfere with other switch hardware or rack equipment.
