10 IF2 Network Reader User Guide
Establish the earth ground connection by attaching a ground wire or braid to one
of the mounting nuts next to the data interface connectors or to any antenna ter-
minal. The base of the IF2 case is magnesium and this surface will NOT provide
adequate grounding.
How to Provide Adequate Heat Sinking
The IF2 contains thermal protection to prevent it from being damaged by operation
at high temperatures. This protection disables the transmitter if it gets too hot. The
IF2 will not overheat in most cases if the ambient temperature is cooler than 40
º
C
(104
º
F).
Adding a heat sink to the rear plate of the IF2 may provide adequate cooling to
allow continuous reading operation in high temperature environments, such as
what you might encounter inside of an unventilated enclosure. Periodic external
triggering of the IF2 to read tags will help keep the internal temperatures low
enough to operate without an additional heat sink.
Note: Make sure you provide adequate heat sinking in high temperature environments if
you intend to leave the IF2 reading tags continuously. If you externally trigger the IF2
to read a tag for two seconds every 30 seconds, it will not require additional heat
sinking.
Install the IF2
1. Choose a mounting location that meets these environmental requirements:
• Operating temperature between
-20
º
C (-4
º
F) and 55
º
C (131
º
F).
• Storage temperature between
-30
º
C (-22
º
F) and 70
º
C (158
º
F).
• Humidity (non-condensing) between 5% to 95%.
2. Provide an adequate heat sink if the reader will operate continually or is
mounted outside or in an enclosure.
3. Use the IF2 Network Reader Drilling Template Instructions to drill holes in the
mounting location.
4. Mount the IF2 using your parts and screws.
