MANUALE INGLESE AMPLIFICATORE HVLA700AY REV.0

PACKING
After removing the amplifier from its packing, that you have to keep conserved, verify carefully that it hasn’t
suffered damage in consequence of transport; in that case contact us immediately.
DISLOCATION
Place the amplifier in a way that all the controls are easily accessible and put it in a place far from souces of
heat. Is very important that the air circulates plentifully on every side of the amplifier setting it therefore far
from other objects.
GROUNDING
To avoid electrical shocks, RF and/or TVI interferencies, we advise you to connect the amplifier to a good
electrical safety ground with the proper terminal labeled “GROUND” placed on the back. The connection has to
be as much short as possible and with the suitable section. Do not connect with gas and water mains, radiators
and/or metallic structures. You must always connect the “GROUND” of the amplifier to the “GROUND” of the
transceiver.
ELECTRICAL CONNECTION
IMPORTANT: verify that the AC socket and the relative power line are according to law and that
they have the minimum characteristics to deliver the maximum power required by the amplifier.
CONNECTIONS
a) Connect, with a quality 50 ohms coaxial cable headed with PL259 connectors, the antenna SO-239 connector
of the transceiver to the SO-239 connector labeled “RF IN”, placed on the back of the amplifier.
b) Connect the antenna, with a quality 50 ohms coaxial cable headed with PL259 plug to the output SO-239
connector labeled “RF OUT” placed on the back of the amplifier.
NOTE:
In order to verify constantly the efficiency of the amplifier and of the antenna system, we recommend
to use a good “VSWR-Wattmeter” instrument connected to the antenna and to verify that, coaxial cable and
antenna, are able to bear the maximum power delivered by the amplifier.
c) Connect, with a shielded audio cable, the ALC input of the transceiver with the female RCA plug labeled “ALC
OUT” placed on the back of the amplifier.
NOTE:
refer to what is reported in the “APPENDIX” at the end of the manual.
d) Connect, with a shielded audio cable, the output of the transceiver dedicated to the drive of the linear
amplifier with the female RCA plug labeled “RELAY” placed on the back of the amplifier.
NOTE:
refer to what is reported in the “APPENDIX” at the end of the manual.
NOTE:
the switching occurs closing to ground the input and it can be done by a electromechanical contact
(relay) or by a signal with to ground going level; refer also to the user manual of the transceiver.
e) Connect the power cable to the AC socket verifying that the voltage value corresponds to the one of the
amplifier.
