Installation manual
Safety and Warranty 
GENERAL 
All cables for the Fleet33 system are shielded and should not be affected by 
magnetic fields. However, if possible do not run cables parallel to AC wiring – 
failing to do so might cause the equipment to be faulty or working properly. 
SERVICE 
User access to the interior of the Transceiver Unit is prohibited. Only 
technicians authorised by Thrane & Thrane A/S may service the unit - failing to 
do so will void the warranty. Access to the interior of the Antenna Unit is 
allowed, but only for replacement of certain modules - as described in this 
manual. General service on the unit may only be performed by a technician 
authorised by Thrane & Thrane A/S - failing to do so may void the warranty. 
RADAR SAFETY DISTANCE 
Do not move the antenna closer to radars than the minimum safety distance 
specified in this manual - this will possibly damage the antenna eventually. 
Equipment must be installed with a minimum safe distance to magnetic 
steering compass of at least 1.1 m. Personal safe distance is 1.3 m from the 
antenna while it is transmitting. 
GROUNDING, CABLES AND CONNECTIONS 
The Transceiver Unit must be grounded at its grounding stud. 
The shielded cables must generally be grounded in both ends, except for the 
cable between transceiver and Cradle, which shall not be grounded in the 
Cradle end. Connections of all types of equipment must be done while the unit 
is switched off. 
Do not extend the cables beyond those specified for the equipment – except 
the cable between the transceiver Unit and the antenna unit. This can be 
extended if it complies with the specified data concerning cable losses etc.
