Radio Interference Sources (for Guidance Only)

In general the FAU will be unaffected by radio transmissions operating in the vicinity
of an installation. However, there are a small number of situations close to radio
transmitters where care should be taken in assessing the suitability of the site for
installing an FAU. If due care is not taken possible mis-operation of the FAU may
result or, in extreme cases, even damage.
NOTE:
assumed throughout.
General Radar
An FAU may suffer damage if placed closer than:
• 250 m of a general radar station operating near to the FAU receive band.
• 150 m of a general radar station operating in the 5 GHz region.
Fixed Radio Services Operating in the FAU Receive Band
An FAU may be rendered inoperable if placed closer than:
• 150 m from the centre boresight of a digital point-to-point microwave radio link.
• 700 m of a digital point-to-multipoint base station using an omni-directional

Cable Routing

The recommended cable types for use with the FAU allow the following maximum
separations:
Cable between FAU and DC Power Supply
For all applications, the cable between the FAU and its DC power supply should be
kept as short as possible, up to a maximum separation of 50 metres using standard
power cable. See Technical Data - Cables, for recommended cable types. Refer to
"Power Cable Lengths" on page 24 for relationship between cable gauge and
maximum length.
