2. Apply 48 VDC from your power supply or AC mains power (depending on whether amplifier
has optional power supply) to the amplifier with the supplied line cord. The fans will power on.
Check that all four fans are running.
3. Visually check the indicators on the front of the amplifier and verify the following:
a. The PWR ON indicator (green) is on.
b. All other LED indicators (red and yellow) are off.
4. Set the external exciter power level so that it is within the specified input power range and apply
the RF signal to the amplifier input port. The amplifier will deliver nominally 350W at the output
connector. The green exciter drive status LED will illuminate when the RF drive is detected.
This LED is meant to give the user a general indication that the exciter is active and is
delivering output power when troubleshooting an alarm condition. However, it does not indicate
that the minimum input power level has necessarily been reached.
5. Remove the RF input signal. The output power will drop to zero. Only the Power On indicator
will be illuminated. Amplifier is ready for use.
