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.
