ESD GROUNDING:
HWR-014
ESD Hardware Kit
ESD refers to the OPTIONAL static dissipative laminate used on the bench. The laminate has a
conductive under layer that comes in contact with the factory installed grounding bolts in the
worksurface. The ESD grounding kit, including the 10 ft. grounding wire must be attached and the
bench must be properly grounded to your facility earth ground.
(See below for grounding
cautions!)
The eyelet slips over the bolt end and the alligator clip attaches to ground. When tested
with a megohmmeter the ground bolts should test at 1 (1x10
6
) to 1000 (1x10
9
) in accordance with
EOS/ESD standards prescribed in EOS/ESD document S4.1-1990 Worksurfaces-Resistive
Characterization. For specific details on grounding the bench consult EOS/ESD document S6.1-1991
Grounding - Recommended Practice.
GROUNDING CAUTIONS:
1.) Ground each bench individually to ground,
NEVER t
o each other in a continuous daisy chain.
2.) ISOLATED ground receptacles should not be used to derive an ESD ground.
3.) The green wire in a standard wall duplex can be used as a ground if it has been absolutely
determined that the green wire is attached to earth ground in your facility, thereby providing a real
earth ground.
4.) Each component of an ESD station should be connected to the same common ground point. In
other words, use only ONE of the ground bolts as a path to ground. There are 2 installed for
convenience only, or in the event you purchase a continuous resistance monitor.
