Grounding methods

There are several methods for grounding. Use one or more of the following methods when handling
or installing electrostatic sensitive parts:
Use a wrist strap connected by a ground cord to a grounded workstation or computer chassis.
Wrist straps are flexible straps with a minimum of 1 megohm ±10 percent resistance in the
ground cords. To provide proper ground, wear the strap snug against the skin.
Use heel straps, toe straps, or boot straps at standing workstations. Wear the straps on both
feet when standing on conductive floors or dissipating floor mats.
Use conductive field service tools.
Use a portable field service kit with a folding static-dissipating work mat.
If you do not have any of the suggested equipment for proper grounding, have an HP-authorized
reseller install the part.
NOTE: For more information on static electricity or assistance with product installation, contact
your HP-authorized reseller.
