Grounding Static Protected Worksurfaces
In order to prevent a possible electrical
shock hazard to personnel, the static
protected laminate should not be directly
connected to ground at any point.
Recommended grounding procedures
suggest installing an in-line 1 MEG OHM
current limiting resistor between the static
protected laminate and the ground.
Electrical (Hydro) grounding circuits may
not be at actual ground potential. It is
recommended that a separate ground
circuit be installed for the static protected
worksurface.
If your worksurface was not supplied with a
factory drilled grounding location, use a
7/32” drill bit to drill into the worksurface in
the desired location ensuring that no
structure will obstruct the bolt. IT IS
IMPORTANT TO USE THE CORRECT
SIZE DRILL BIT TO ENSURE PROPER CONTACT WITH THE CONDUCTIVE LAYER. Install the
brass ground bolt. Lightly hammer the knurl into the worksurface until the bottom of the bolt head is
flush with the laminate. Install washer, brass nut, ground lead, and brass nut as shown. Do not over
tighten the nut, snug down firmly to ensure contact between the bolt and the laminate.
Common Point Ground Block
The purpose of a common point ground
block is to bring all required ground leads
to a common ground point. If a common
point ground block is required, it should be
mounted (using the attached adhesive
strips) on the underside of the worksurface
in a convenient place, out of the way but
accessible from both sides. Note one side
of the base is embossed with the indication
1 MEG OHM. All connections made on
the other side of the common point ground
block will be connected directly to ground.
Connect ground leads from the brass
ground bolt and the dual wrist strap
receptacle to the direct to ground side of the common point ground block. Ground leads from any
electrical equipment should also be connected to the direct to ground side. Ground leads from the
metal frame of the workstation and/or other metal accessories should be connected to the one mega
ohm side of the ground block. Ensure all ground leads are tucked away neatly to prevent accidental
disruption of ground connections.
