Power Consumption 

The equipment is rated for operation over the range 100 - 240 Volts AC. It has a maximum power 
consumption of 60 Watts, and draws a maximum of 600 mA. 

4.3 

Fuses 

The LNA is fitted with two fuses - one each for line and neutral connections. These are contained 
within the body of the IEC power inlet connector, behind a small plastic flap. 

For 115 and 230 volt AC operation, use T1.25A, 20mm fuses. 

4.4 

Cables and Connectors 

The LNA is shipped with a line inlet cable suitable for use in the country of operation.  

If it is necessary to replace this cable, make sure the replacement has an equivalent specification. 

Examples of acceptable ratings for the cable include HAR, BASEC and HOXXX-X.  

Examples of acceptable connector ratings include VDE, NF-USE, UL, CSA, OVE, CEBEC, 
NEMKO, DEMKO, BS1636A, BSI, SETI, IMQ, KEMA-KEUR and SEV. 

4.5 

Operating Requirements for Regulatory Compliance 

To maintain continued compliance with the European Directives: 

 

Make connections to the Tx and Rx IF ports (Type N or Type F connectors using a good 
quality coaxial cable - for example 50 

 or 75 

 

Make sure all D type connectors attached to the rear panel have back-shells that provide 
continuous metallic shielding. Cable with a continuous outer shield (either foil or braid, or 
both) must be used, and the shield must be bonded to the backshell. 

 

Make sure the equipment operates with its cover on at all times. If it becomes necessary 
to remove the cover, make sure that the cover is correctly reinstalled before normal 
operation resumes.
