Operating and installation instructions
RF-KIT Power Amplifier RF2K-S
4. Preparing for operation
4.1 Unpacking
►
After unpacking, inspect the device for shipping damages.
►
Report any damage immediately to the delivering freight forwarder
or dealer. Keep the shipping box.
4.2 Scope of delivery
1x RF2K-S Power Amplifier
1x 120 V AC line cord
1x 240 V AC line cord
1x Short coaxial cable with 1x SMA connector (“Pigtail“)
1x Micro SD-Card for operating system
4.3 Selecting a location
Because of its weight the device must be situated on a stable surface.
►
Select a location for the device that ensures adequate air circulation
(at least 10 cm of free space in front of and behind the PA are
neccessary).
►
Avoid locations with extreme heat or cold, high humidity and
vibrations.
Avoid operation near TV sets, television antennas, radios and other elec-
tromagnetic sources.
4.4 Grounding
WARNING!
NEVER connect the Ground connector (11) to a
gas or power line, as this may cause an explosion
or a electric shock!
To prevent electric shock, television interference (TVI), radio interference
(BCI) and similar problems:
►
Ground the device via the Ground connector (11) at its back.
For best results, use a copper wire with large cross-section to connect
to a copper rod, as long as possible, buried in conductive soil.
►
Keep the length of this copper wire as short as possible!
4.5 Connecting exciter
►
Connect the antenna socket of the exciter (a transceiver in general)
to the connector TRX (17) of the PA via a coaxial cable.
4.6 Connecting PTT-cable
►
Connect the PTT connector of the exciter (a transceiver in general)
to the connector PTT (7) of the PA via a RCA cable.
At the center contact (+) of the connector PTT (7) +5 V are
present.
4.7 Preparing LAN connection
►
Connect a ethernet cable to the LAN (13) socket.
►
Connect the ethernet cable to the router / switch of your local area net-
work.
4.8 Connecting antenna(s)
Do NOT transmit without an antenna or dummy load connected! Select
one or more 50 Ω antennas or dummy load with 50 Ω lead and more than
2 kW rated power.
►
Connect 1-4 antenna(s) to the desired 50 Ω antenna socket using
suitable coaxial cable with as little loss of power as possible, and pro-
fessionally mounted SO-239 plugs to connector ANT 1 (6), ANT 2 (5),
ANT 3 (3), ANT 4 (4).
ANT 1 (6) is looped through as long as device is “off“.
4.9 AC Line cord connection
The device works with mains voltages between 90 and 290 V AC. We re-
commend the use of 200-240 V / 50-60 Hz AC to ensure the full performan-
ce of the device.
If the device is operated at 110 V, the maximum output power drops from
approximately 2000 W to approximately 900 W.
►
Connect the device with the included line cord via Power jack (9) to a
properly installed power outlet.
