PRELIMINARY PRECAUTIONS

Before you start to install the amplifier, fully read this manual. Carefully remove the amplifier from
its boxes and packaging materials and inspect for physical damage incurred during shipping.
If any damage is found contact immediately your supplier.
Keep the original boxes and packaging materials; if factory service is required, the amplifier must
be shipped using the original boxes and packaging materials.

5.1 Amplifier location

The amplifier must be located in a cool and dry area with large space around the amplifier to allow
good ventilation to all surfaces and free flow of the air. Don't obstruct the entries for cooling
present in the cover of the amplifier and don't place the amplifier near walls or other obstacles.
Reduced airflow conditions can severely damage the amplifier ! ! !
5.2 Connection to AC power supply
The amplifier features an internal high efficiency switching power supply. It accepts the wide AC
line voltage ranging from 100 VAC to 264 VAC 50/60 Hz automatically. Before connecting the
amplifier verify that your mains supply is in accordance with the specifications of the amplifier. The
amplifier must be connected directly to the mains supply with the supplied AC power cord, without
the use of adaptors or other accessories. Before connecting the amplifier to your mains supply, be
sure that the supply is correctly wired and rated for the current drawn by the amplifier (up to 10
A). The installation leads must be at least 1,5 mm² or #15 AWG. If you connect the amplifier to a
different mains outlet, be sure that you check it, too.
5.3 Ground
Connect the ground stud of the amplifier (on the rear panel, marked "GROUND") to the station's
grounding system. A proper ground connection will result in reduced RF strays or noises and avoid
points of RF high voltages during transmission on metallic objects that may come into contact with
the operator.
5.4 Antenna
The amplifier is designed for use with antennas that present an impedance of 50 ohms at the
operating frequency. Connect a coaxial cable from the amplifier output (on the rear panel, marked
"ANT A" and "ANT B") with a PL-259 plug to the antenna for the respective band. We
recommend, that you use RG213 or better coaxial cable. If antenna VSWR is high at operating
band , the antenna has to be adjusted for lower VSWR; in this condition an antenna tuner must be
inserted.
