Control cable
With the control cable ensures switching from reception to transmission. The cable is shielded. On the
side of the power amplifier a CINCH-socket is used. On the side of your transceiver you have to use a
socket suitable for this transceiver. During transmitting the middle pin is connected to the ground.
The relays of the OM3006 have to be switched earlier than HF is applied (cold switching).
Modern transceivers have a time delay between PTT switching and power output.
If you are using and older transceiver or transmitters without time delay we recommend to connect the
PA in such a way that the transmit/ receive switch is connected with the KEY IN socket of the
amplifier. The KEY OUT socket is to be connected with the PTT socket at the transceiver.
The amplifier is equipped with two safety devices, which ensure that the Output relay is not switched
under power mistakenly (hot switching).
MAIN SUPPLY:
The amplifier is connected to the mains with 2 cables with an EURO end. Each cable is to be
switched to another phase of your main supply system! Both of them have to be able to deliver a
power of 2.5 kVA !
If you use only one phase, you have to connect both cables to this one phase ! Your main supply
has to be able to deliver 3,5 kVA on this one phase! In this case the power amplifier can’t
deliver full output!
ATTENTION:
In each case the power amplifier has to be connected
to your main supply system with the 2 cables!
Normally the amplifier is used at 2 phases. If there is
only one phase connect the 2 cables to this one!
Grounding
The amplifier has to be grounded properly! Connect the screw on the rear panel of the amplifier to
your local grounding system with a copper-cable, use a cross-section of 4 mm
2
at least.
Connect your transceiver to the same grounding system of your shack carefully!
If you use a power amplifier with higher output you have to be aware that your grounding system
works properly. All parts have to be grounded to the same system. Use short cables and make sure
that there are good contacts! Otherwise you run the risk of damaging your equipment, having
problems with TVI/BCI or your signal may be distorted.
