Required Tools and Equipment
After you install the system ground lug, follow these steps to correctly attach the ESD wrist strap:
Before you begin
To connect the ground system, you need the following tools and materials:
• Grounding lug—A two-hole standard barrel lug. Supports up to 6 AWG wire. Supplied as part of accessory
• Grounding screws—Two M4 x 8mm (metric) pan-head screws. Supplied as part of the accessory kit.
• Grounding wire—Not supplied as part of accessory kit. The grounding wire should be sized according
Note
• 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.
Step 1 Attach the ESD wrist strap to bare skin as follows:
a. If you are using the ESD wrist strap supplied with the FRUs, open the wrist strap package and unwrap the ESD wrist
strap. Place the black conductive loop over your wrist and tighten the strap so that it makes good contact with your
bare skin.
b. If you are using an ESD wrist strap equipped with an alligator clip, open the package and remove the ESD wrist strap.
Locate the end of the wrist strap that attaches to your body and secure it to your bare skin.
Step 2
Grasp the spring or alligator clip on the ESD wrist strap and momentarily touch the clip to a bare metal spot (unpainted
surface) on the rack. We recommend that you touch the clip to an unpainted rack rail so that any built-up static charge is
then safely dissipated to the entire rack.
Step 3 To plug the strap into the port (and alternatively clip an alligator clip onto the grounding lug screws) attach either the
spring clip or the alligator clip to the ground lug screw.
a. If you are using the ESD wrist strap that is supplied with the FRUs, squeeze the spring clip jaws open, position the
spring clip to one side of the system ground lug screw head, and slide the spring clip over the lug screw head so that
the spring clip jaws close behind the lug screw head.

kit.
to local and national installation requirements. Depending on the power supply and system, a 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.
For safety on a ground fault, we recommend that you should avoid using a
grounding wire that is smaller than the power wire. The grudging wire must be
sized to meet local and national standard for installation requirements.
The spring clip jaws do not open wide enough to fit directly over the head of the lug screw or the lug
barrel.
