Connection and start-up
PREPARATION:
To
connect the amplifier to coaxial cables, you must first fit them
with F connectors 75 Ohm. F connectors are available in various
designs, so that direct connection of different cable diameters is
possible.
The following describes how to connect the amplifier and coaxial ca-
bles:
TASK
1. Plug the F connectors into the corresponding sockets of the
amplifier (input [6] and output [5]) and screw the outer ring of
the F connector tight.
2. Make sure the coaxial cables are laid with a sufficient bending
radius.
3. Connect the device to the mains voltage by inserting the mains
plug.
RESULT:
Th
e device is now ready for operation. The power indicator lights
up.
Configuration
The device is delivered with all attenuators in the forward and return
paths screwed in. To operate the amplifier, they must be set accord-
ing to the requirements of the cable network.
The jumper for setting the interstage slope is set to
0dB
NOTE: All attenuators in the forward and return paths have
an attenuation range greater than 15 dB, but the speci-
fied
characteristics can only be provided up to an attenuation
value of 15 dB.
ATTENTION: The device is delivered with all
attenuators screwed in to avoid a possible network
malfunction or the destruction of the device during
operation. This setting must not be changed in networks
that do not use a return path!
