Eclipse Installation Manual
RF Exposure
To ensure compliance with the FCC RF exposure requirements, a minimum distance of
20 meters must be maintained between the antenna and any persons whilst the unit is
operational. This calculation is based on the maximum conducted power and
maximum antenna gain.
Power Supply
Connection
The Eclipse INUs have the +ve pin on their dc power supply
connector connected to chassis ground. It must be used with a
-48 Vdc power supply which has a +ve ground; the power supply
ground conductor is the +ve supply to the radio. For NEBS
compliance the battery return connection is to be treated as a
common DC return (DC-C), as defined in GR-1089-CORE.
• There must be no switching or disconnecting devices in this
ground conductor between the dc power supply and the point of
connection to an Eclipse system.
The Eclipse High Power IRU 600 supports wide-mouth +/-21 to
+/-60 Vdc operation. Both pins on its power supply connector are
isolated from chassis ground. For NEBS compliance the battery
return connection is to be treated as an isolated DC return (DC-I),
as defined in GR-1089-CORE.
The power supply for an Eclipse system must be located in the same
premises as the Eclipse system.
Power Supply
Disconnect
An appropriate power supply disconnect device should be provided
as part of the building installation.
Rack Mount
Temperature
Considerations
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.
Restricted Access 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 antenna location must
be restricted
Note: For USA:
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.
