The 09740/09741, 09835/09836 and
09820/09821/09825/09826/ are shipped with an
extra ring terminal so that the ground wire may
be cut to length during installation. The
09740/09741 and 09835/09836 feature a pair of
mounting holes designed to accommodate
standard #10 screws, allowing the units to be
mounted to the work bench.
Proper Grounding
Wrist straps, work surfaces, floor mats and other
electrostatic discharge (ESD) protective
products should be grounded to a common point
ground.
COMMON POINT GROUND
Per ANSI/EOS/ESD S6.1, Grounding paragraph
4.1.1 "Every element to be grounded at an ESD
protected station shall be connected to the same
common point ground."
ESD Handbook TR 20.20 paragraph 5.1.3 Basic
Grounding Requirements "The first step in
ensuring that everything in an EPA is at the
same electrical potential is to ground all
conductive components of the work area
(worksurfaces, people, equipment, etc.) to the
same electrical ground point. This point is called
the common point ground. The next step in
completing the ground circuit is to connect the
common point ground to the equipment ground
(third wire, green)."
If all elements are connected to the common
point ground, even if the equipment ground
connection is compromised, all workstation
elements will be connected and be at equi-
potential or at the same charge. Being at the
same electrostatic charge will mean that no
discharge should occur.
Connect the ground wire directly to the nearest
utility “green wire” ground point. In a properly
wired building, the “green wire” equipment
ground point may be the center screw of the
standard 110VAC outlet. Some special outlets
may “float” the center screw. Test before you
hook up.
Figure 7. Recommended grounding point.
Individual work stations must be individually
grounded to the “green wire” equipment ground.

Common Point Grounding Units
Installation Instructions
Description
Per ANSI/ESD S20.20, all conductors, including
personnel, must be electrically connected and
attached to a known ground. EOS/ESD S6.1
recommends hard ground, without resistor, of
worksurface or floor mats. Per ANSI/ESD
S20.20, ground fault circuit interrupters (GFCI)
should be considered to provide personnel
protection.
Desco offers a number of common point
grounds and wrist strap ground connectors
designed to ground multiple operators or items.
Figure 1. 09740/09741 wrist strap bench ground.
The 09740/09741 wrist strap bench ground is a
wrist strap ground connector and consists of a
mounting bracket with two standard banana
jacks installed and soldered to a ten foot ground
wire terminated with a ring terminal with a
0.200" hole.
The 09741 includes a wrist strap parking station.
See figure 2.
Figure 2. 09741 premium bench mounted
ground with parking station
The 09837 Multi Grounding Hub is designed for
use as either a wrist strap ground connector or
as a common point ground for all items to be
grounded at a bench (i.e. table mat ground cord,
floor mat ground cord, banana jack ground
block, etc.). The Multi Grounding Hub
Figure 3. 09837 Multi Grounding Hub
incorporates six standard banana jacks, and six
terminations for ring terminals (10-32 screw in
threaded holes).
Figure 4. 09835/09836 quad common point
ground
The 09835/09836 quad common point ground is
designed for use as either a wrist strap ground
connector or as a common point ground. The
quad ground incorporates four standard banana
jacks, a 10mm snap stud, and ten feet of ground
wire terminated with a ring terminal with a
0.200" I.D. hole. The model 09835 also
incorporates a 1 megohm resistor in series with
the snap stud.
Figure 5. 09820/09821/09825/09826
common point ground.
The 09820/09821/09825/09826 common point
ground is designed to ground bench mats by
snapping on the mat’s stud, and to provide a
convenient wrist strap ground connector. Items
09820/09821 incorporate two standard banana
jacks, a 10mm snap socket, and 10 feet of wire
terminated with a ring terminal with a 0.200" I.D.
hole. Items 09825/09826 have a 10mm snap
stud and 15 feet of wire. Items 09821/09826
also incorporate a one megohm resistor in
series with the snap.
Figure 6. All elements at the ESD work station
should be connected to the same common point
ground, such as 09837 Multi Grounding Hub.
