1 Ensure the prime power is within the specified limits of the amplifier.
The correct power input connector pins must be used. These pins
are determined by the voltage level and the prime power source.
Refer to the appendix titled Mechanical Drawings and the chapter
titled Unpacking and Installation for connector pin outs.
2. If the amplifier is installed in a cabinet ensure that the exhaust air
from the amplifier is vented to the outside of the cabinet so that the
warm air is not recirculated into the amplifier intake.
3. Ensure that the RF Output is terminated with a load capable of
dissipating the power of the amplifier. This load should have a
maximum VSWR of 1.3:1.
4. Ensure that the RF drive signal is within the frequency range of the
amplifier specification. Refer to the appendix titled Specifications for
frequency and rated power gain.
Do not exceed the RF Input power limit as defined in
the product specification. Doing so will cause a Helix
Current Fault. Failure to comply could result in
permanent damage to the amplifier.
Überschreiten Sie nicht die in der Produktspezifikation
angegebene Begrenzung der RF-Eingangsspannung.
Sie verursachen sonst einen Helix Strom mangel.
Nichtbeachtung kann zu einer bleibenden Schädigung
der Verstärker führen.
To prevent XTD electrical problems the power ON/OFF
switch sequence must be followed exactly. Failure to
comply could result in equipment damage.
Zur Vermeidung elektrischer Probleme bei der XTD
muss die Schaltablauffolge Power ON/OFF exakt
eingehalten werden. Nichtbeachtung dieses Ablaufs
kann Schäden am Gerät zur Folge haben.
