shoes. These foot grounders
include a molded external
resistor and a permanently
attached grounding tab.
1. Place foot grounder
on the shoe so that the
blue lining is making
contact with the shoe.
2. Insert the grounding tab
inside of the shoe and
under the foot.Make
sure that a solid
contact is made
between the sock
and body. Cut
grounding tab to
desired length.
3. Pull the
strap through the D-ring
and clinch down for a snug,
comfortable fit.
4. Test each foot grounder
to confirm proper
installation.
HEEL GROUNDER WITH SNAP-LOC
FASTENING SYSTEM
The Desco model 07515, 07522, and 07523 heel
grounders are equipped with a Snap-Loc quick
release fastening system. The model 07515 has a
cup and lining that will not mar shoes or floors. The
07515 has a molded exterior 2 megohm resistor,
while the 07522 and 07523 have a 1 megohm flat
“flex” resistor.
1. Insert the grounding tab inside
of the shoe and under the foot.
Make sure that a solid
contact is made between
the sock and body. Cut
grounding tab to desired
length.
2. Fit the heel cup snugly to
shoe and connect the Snap-Loc
fastener together. Adjust elastic
strap for comfortable fit. Tuck
excess elastic strap behind itself.
3. Test each heel grounder to confirm proper installation.
Cleaning
Foot grounders are to ground static charges, while
dirt generally provides an insulative layer adversely
effecting reliability. For proper operation, the Foot
Grounder and its conductive strip must be kept clean.
The rubber portion of the Foot Grounder should be
cleaned using Desco’s Rezstore™ Antistatic Surface
& Mat Cleaner or “Static-Wipes” wipers. An alternative
would be to clean using isopropyl alcohol. The Desco
cleaning products are specially formulated for cleaning
ESD control components and are silicone free. This is
critical as silicone is an insulator. Desco ESD
cleaners should not be used to clean the nylon
polyester grounding tab.
Foot Grounders can be safely hand or machine
washed on gentle cycle. Mild detergents, such as
Woolite
®
or a liquid dish washing product and warm
water are recommended. However, care must be taken
to ensure that these detergents are silicone free.
Installation
HOOK & LOOP AND MARR RESISTANT
HEEL GROUNDERS
Desco model 07560, 17200, 17202, 17210, 17250,
and 17252 heel grounders are designed for use on
standard shoes. All Desco foot grounders can be
easily adjusted to fit the individual wearer. Desco heel
grounders have a dissipative lining that will not mar
white or light colored shoes. Models 07560, 17200,
17202, and 17252 have a current limiting one or two
megohm resistor in series with the grounding tab.
Models 17250 and 17210 have no resistor.
1. Place the foot grounder on
the shoe so that the lining is
making contact with the
shoe.
2. Insert the grounding
tab inside of the shoe
and under the foot.
Make sure that a solid
contact is made between
the sock and body. Cut
grounding tab to desired
length.
3. Fasten hook and
loop straps together,
securing foot grounder
firmly on shoe.
4. Test each foot
grounder to confirm
proper installation.
D-RING HEEL GROUNDERS
Desco model 07590 and 07593 heel grounders are
equipped with an elastic D-ring fastening system
which provides snug cinching of the ankle strap and
allows "flex" during walking. They are designed for
use on most types of shoes and boots. The light blue
lining prevents marring on white or light colored

Foot Grounders - Grounding,
Testing, and Maintenance
Description
Desco’s complete line of foot grounders has been
created to provide a continuous ground path between
the operator and a properly grounded ESD protected
flooring. Foot grounders are designed for use in
applications where user mobility is required, such as
wave solder, kitting, and quality control. Per
ANSI/ESD S20.20 Paragraph 6.2.2.2, “ESD
protective flooring used with approved footwear, may
be used as an alternative to the wrist strap system for
standing operations.” Foot grounders quickly and
effectively drain the static charges which collect on
personnel during normal, everyday activities.
General Guidelines
1. It is recommended that foot grounders be worn on
both feet, in order to assure that a continuous path to
ground is maintained.
2. Grounding tabs should be tucked inside the shoe
with as much contact area as possible to the bottom
of the stockinged foot. Foot grounders rely upon the
perspiration in the shoe to sustain electrical contact
between the conductive grounding tab and the body.
3. Foot grounders should be used in conjunction with
floor surfaces which have a surface resistance of less
than 1 x 10 9 ohms.
4. A current limiting one or two megohm resistor in
series with the grounding tab is recommended.
Models 07504, 07505, 07506, 07507, 07508, 07509,
07515, 07522, 07523, 07560, 07590, 07593, 07595,
17200, 17202, 17222, 17252, 17280, 17281, and
17282 are listed.
Testing Your Foot Grounders
The best test of your foot grounder is one that
includes all three components: the individual foot
grounder, the grounding tab and the interface
between the grounding tab and the wearer’s sweat
layer.
Desco has testers designed to properly test foot
grounders. For more detailed information on these
testers, ask for technical bulletins TB-2040 (19252,
19253), and/or TB-3000 (98280).
If you obtain a fail reading from the tester you should
stop working and clean the foot ground and
grounding tab. Retest after cleaning. If the unit still
fails, replace the foot grounder. Retest the system
before beginning work.
