1.0 INTRODUCTION
Each ETS-Lindgren Double Electrically Isolated (DEI) Enclosure is tested at the
factory to verify that it provides the proper shielding.
1.1 ETS-LINDGREN PRODUCT INFORMATION BULLETIN
See the ETS-Lindgren Product Information Bulletin included with your shipment
for the following:
• Safety, regulatory, and other product marking information
• Steps to receive your shipment
• Steps to return a component for service
• ETS-Lindgren calibration service
• ETS-Lindgren contact information
Take care when
assembling the DEI
enclosure to avoid
causing an RF leak; an
RF leak can be created
by simply tightening a
bolt improperly.
An RF leak can
cause a large loss in
attenuation. At final
RF attenuation testing,
a low reading would
indicate a leak, or many
leaks, in the shielding.

3.0 BEFORE YOU BEGIN ASSEMBLY
3.1 INSPECT CONTACT EDGES
The most critical parts of each frame are the surfaces that connect the panels,
the two contact surfaces along the edges.
• Keep the contact edges clean at all times.
• As the room is being assembled, visually inspect all of the contact surfaces.
This inspection is especially important on an all metal enclosure (not a
screen room).
• The contact surfaces should be free of any paint, grease, dirt, and corrosion.
If the panels were stored in a damp environment, the edges may be
slightly corroded.
For information
on cleaning
contact surfaces, see
the Cleaning Contact
Surfaces section of
this guide.
Before assembling any
components, follow
the safety information
in the ETS-Lindgren
Product Information
Bulletin included with
your shipment.

4.0 ASSEMBLY AND INSTALLATION
4.1 OVERVIEW OF ASSEMBLY STEPS
1. Clean the area to be used for construction of the room.
2. Mark out the space on the floor where the room will be built.
3. To prevent damage to panels, remove panels from the crates or cartons only
as they are needed.
4. Locate, position, and bolt together the floor panels as shown in
the illustrations.
5. After the main floor panels are assembled, place the interior floor panels
(with floor tile) on top of them.
6. Attach the 4 in wide aluminum strips between each of the interior panels
and secure with the wood screws.
Wall and ceiling panels should be assembled as shown in the illustrations
7. Be sure to securely bolt the wall panel seams before inserting and
tightening the 4 in bolts into the floor panels.
8. Check alignment of the panels as they go together to avoid having to
disassemble and re adjust them later.
9. To ease insertion of the ceiling panels, loosen some of the 4 in bolts to allow
for some movement of the wall panels.
10. When inserting and tightening the 4 in bolts into the ceiling panels,
maintain solid contact along all of the seams.
4.2 ASSEMBLY STEPS
STEP 1 - CLEAN AREA
Remove all debris and clean the area where the enclosure is to be installed.
STEP 2 - MARK LOCATION
Use the illustrations in this manual to determine the area required for the
enclosure. Mark the location on the floor.
Review all
steps prior to
starting to assemble the
DEI enclosure.
Before assembling any
components, follow
the safety information
in the ETS-Lindgren
Product Information
Bulletin included with
your shipment.
To accommodate
a site with limited
access space, the
DEI enclosure can be
pre-assembled and
moved into position.
When moving a pre-
assembled enclosure,
take care to avoid
contact with all metal
objects (such as
ductwork).

12
STEP 3 - OPEN CRATE
STEP 4 - ASSEMBLE MAIN FLOOR PANELS
Open all crates
and cartons
in the numbered
sequence, which
indicates the order of
panel construction.
To prevent damage to
panels, remove panels
from the crates or
cartons only as they
are needed.
In numbered
order, place
the main floor panels
on the marks made in
step 2.
To remove a panel,
loosen the crate lumber
or disassemble the
crate. Do not force the
panel from the crate if it
becomes jammed.

13
STEP 5 - PLACE INTERIOR FLOOR PANELS
STEP 6 - ERECT WALL PANELS
FOR LARGE ROOMS:
Place the
interior floor
panels (with floor tile)
on top of the assembled
main floor panels.
Begin
construction
of the wall panels at the
end of floor panel
#1 and moving
in a clockwise,
numerical fashion.
Attach the
4 in wide
aluminum strips
between each of the
interior panels and
secure with the
wood screws.
Verify that the floor is
level before assembling
the DEI enclosure or
leaks will occur.

14
STEP 7 - BOLT WALL PANELS
STEP 8 - INSTALL FINISHED FLOOR
Tighten clamps
and align all
panels before inserting
and tightening the
4 in bolts.
Panels can
form leaks,
especially where floor
and wall panels are
joined. Before aligning
the panels, loosen all
bolts on a seam to
ensure a consistent
panel fit. The edges
of the wall and ceiling
panels or wall and floor
panels must
align perfectly.
For more
information
on correcting leaks,
see Correcting Leaks
section of this guide.
Check
alignment of
the panels as they go
together to avoid having
to disassemble and re
adjust them later.
Never use a hammer
directly on the shielding
material.

15
STEP 9 - PLACE CEILING PANELS
4.3 ELECTRICAL COMPONENTS
To ease
insertion of
the ceiling panels,
loosen some of the 4 in
bolts to allow for some
movement of the
wall panels.
Begin ceiling
panel assembly
by positioning the
lowest numbered panel
directly over floor
panel #1.
Place all
panels in the
direction shown in
the illustration.
When inserting
and tightening
the 4 in bolts into the
ceiling panels, maintain
solid contact along all of
the seams.
