Information
When installing an indoor unit in a rack, ensure the rack is securely anchored.
Ensure that the additional loading of a 9500 MXC indoor unit or units will not
cause any reduction in the mechanical stability of the rack.
The 9500 MXC 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 a 9500 MXC
system.
• The power supply must be located in the same premises as the 9500 MXC
system.
An appropriate power supply disconnect device should be provided as part of
the building installation.
If the 9500 MXC 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
9500 MXC indoor unit, which, if installed in a rack, is the ambient within the
rack.
The 9500 MXC 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
Note: For USA:
In restricted access areas install the 9500 MXC system in
accordance with articles 110-26 and 110-27 of the 2002 National
Electrical Code ANSI/NFPA 70.
