Installation instructions
3500782-0001 Revision E
specifications. The cable must not be cut to a shorter length, nor must
any cables be added to the cable run.
•
It is essential that only the supplied cable is used. Third party cables may
not be used; their use will invalidate the warranty of the ODU and may
cause system malfunction.
•
It is important not to stress the connection to the ODU during installation
of the coaxial ODU cable.
•
The minimum bend radius of the cable is 2” (50mm) however; it is
recommended that a 4” (100mm) bend radius be used.
•
Any modification to these rules must be approved by Hughes and
Inmarsat prior to the installation.

3.
Weatherproof the connection using self-amalgamating tape (not provided).
4.
Route the cable to the 9502 IDU avoiding any sharp bends, extremes in
temperature, and compression of the cable.
