RF Exposure Guidelines
The following MPE (maximum permissible exposure) calculations have been produced
in accordance with the guidelines of EN 50383/EN 50385. These calculations
represent examples only and do not include every possible combination of output
power and antenna gain.
Occupational is defined as: "The occupationally exposed population consists of adults
who are generally exposed under known conditions and are trained to be aware of
potential risk and to take appropriate precautions".

Information
The Eclipse radio has the +ve pin on its dc power supply connector
fastened directly to the chassis. It must be used with a -48 Vdc
power supply which has a +ve earth; the power supply earth
conductor is the +ve supply to the radio.
• There must be no switching or disconnecting devices in this earth
conductor between the dc power supply and the point of
connection to an Eclipse system.
• The power supply must be located in the same premises as the
Eclipse system.
An appropriate power supply disconnect device should be provided
as part of the building installation.
If the Eclipse indoor unit is installed in a closed or multi-unit rack
assembly, the operating ambient temperature of the rack
environment may be greater than room ambient. The maximum
ambient temperature (Tmra) of +45° Celsius (113° F) applies to
the immediate operating environment of the Eclipse indoor unit,
which, if installed in a rack, is the ambient within the rack.
The Eclipse system must be installed in restricted access sites. The
indoor unit and associated power supply must be installed in
restricted areas, such as dedicated equipment rooms, closets,
cabinets, or the like. Access to the tower and ODU/antenna location
must be restricted
For USA:
Note:
In restricted access areas install the Eclipse system in accordance
with articles 110-26 and 110-27 of the 2002 National Electrical
Code ANSI/NFPA 70, or to any subsequent update to this code for
the relevant articles.
