VOLUME I, CHAPTER 1, HEALTH AND SAFETY
Topic Information
Maximum Ambient
Temperature
The maximum ambient temperature (Tmra) for Eclipse indoor units
is +55° C (131° F). Special conditions apply to the INUs - for more
information see Power Consumption within Power Supply on page
61. To ensure correct operation and to maximize long term
component reliability, ambient temperatures must not be exceeded.
Operational specification compliance is not guaranteed for higher
ambients.
Mechanical Loading When installing an indoor unit in a rack, ensure the rack is securely
anchored. Ensure that the additional loading of an Eclipse indoor unit
or units will not cause any reduction in the mechanical stability of the
rack.
Power Supply
Connection
The Eclipse INUs and IDUs 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.
On those high power IRU 600s that support an integral wide-mouth
+/-21 to +/-60 Vdc input, 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 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 a 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.
