6 Amplifiers
When the transmitter is delivered, one or two exciters and an R&S NetCCU800 are already
mounted in the rack. The amplifiers, however, are not and must be retrofitted in the rack.
6.1 Installing Amplifiers
Note Before installing the amplifier, make sure that the ventilation covers on the amplifier slots
provided in the frame are open on both sides. Remove the covers if necessary.
Note It is advisable to install the amplifiers in sequence starting at the top and working down to
the bottom.
Install the amplifiers as follows:
1. Carefully remove the amplifier from its packaging.
2. Select the installation position provided for the amplifier in the transmitter rack.
3. Place the amplifier on the guide rails and slide it carefully into the rack as far as it will go.
The amplifier is guided onto the connections by means of guide pins on the rear panel.
4. Secure the amplifier in place using the 4 screws of the two front brackets on the rack.
5. To install additional amplifiers, repeat steps 1 to 4.

WARNING!
Always make sure that the power supply is disconnected before commencing any installa-
tion work on the transmitter rack. This will prevent injury caused by electric shock and
damage to the instruments.
CAUTION!
Always have a second person assist you in installing the amplifiers as the instruments are
very heavy (approx. 28 kg).
