SECOND PHASE OF INSTALLATION
When all the phases of electrical connection are complete and checked, it is possible to close all the panels
of the equipment. Arrange all the other transmission system apparatus in their final positions. Included
with the T30000 unit is a kit of sleeves made from material which are used to close the three wide
access points which correspond to the entrance and exits of the RF cables and the hot air exit. The
application of the three sleeves is clear, their function is to prevent the ingress of insects or organic
vegetable material into the equipment. WARNING! Particular care should be taken with the
connection to the radiating system as the principal cause of functional problems within the first few
hours of operation is caused by an inefficient RF load. The connection phase of the radiating system is
particularly hazardous for the operator since he is not aided by an earth connection; the efficiency of
the earth connection can never be relied upon at radio frequency. The above information is very
important if the transmitter being installed is connected to a multiport radiating system (duplexer,
triplexer, etc...). In this case IT IS NECESSARY TO DISACTIVATE ALL THE TRANSMITTERS
CONNECTED TO THE SAME RADIATING SYSTEM. As in any installation of electronic
apparatus, the final operation is to check that all connections are correct, in particular with this unit it
is essential to ensure that the short-circuit safety connection has been removed from the high voltage
circuit.
