1 Notes about safety and hazards
• The head-end station is subject to the regulations of protection class I.
• Never operate the device without a protective earth connection, earth
connection to the device and potential equalisation!
• Observe the relevant VDE regulations, particularly VDE 0701 parts 1
and 200.
• Should the power cord need to be replaced, only use an OEM power
cord.
• Only replace fuses with fuses of the same type, and which also have the
same cut-off characteristics.
• Earth the SAT receiver system in accordance with DIN EN 50083,
part 1.
• Do not perform installation and service work during thunderstorms.
• Assembly, installation and servicing must be carried out by an authorised
electrician.
• Switch off the operating voltage of the system before beginning with as-
sembly or service work or pull out mains plug.
• Install the system …
- on a vibration-free wall or floor construction
- In a dry, dust-free environment
- In such a manner that it is protected from moisture, fumes, splashing
water and dampness
- Where it is protected from direct exposure to sunlight
- Not within the immediate vicinity of heat sources
- At an ambient temperature between –20 °C and +50 °C
• The device should only be installed in a room where the permissible am-
bient temperature range can be maintained, even during fluctuations in
climatic conditions.
• Ensure that the device is adequately ventilated.
• Do not cover the ventilation openings!
• During installation, make sure there is a minimum space of approx.
75 mm above, behind and underneath the device.
• Do not install the device in cabinets or recesses which are not venti-
lated.
• If additional fans are to be used to circulate the air, ensure that the system
will be shut down (disconnected from mains) should any one of the fans
fail.

• Do not place any vessels containing liquids on the device.
• Due to the risk of fires caused by lightning strikes, we recommend that
all mechanical parts (e.g. distributor, equipotential bonding rail, etc.) be
mounted on a non-combustible base. Wood panelling, wooden beams,
plastic covered panels and plastic panels are all examples of combusti-
ble bases.
• Avoid short circuits!
• Observe the relevant standards, regulations and guidelines on the
installation and operation of antenna systems.
• To ensure electromagnetic compatibility, make sure all connections are
tight and that the covers are screwed on securely.
• No liability is accepted for damage caused by faulty connections or
inappropriate handling of the device.
Take precautions to prevent static discharge when working on the device!

2.4 Description
Proper installation of the mounting bracket enables the OKB 416 head-end
station to be installed in a 19” cabinet as well as on a shelf or on a wall.
The head-end station is modular in design and can be equipped with 8
standard plug-in modules and 8 add-on modules. A current list of the stand-
ard and add-on modules can be found on the website “www.fuba.com”. This
head-end station is designed exclusively for use with these modules.
The various expansion options for the head-end station allow for the installa-
tion of a wide range of broadband cable systems.
Input SAT IF distributors can be upgraded to offer the highest degree of flex-
ibility for the distribution of input signals.
The power supply in the OKB 416 head-end station is designed to supply
power to components (e.g. LNB) connected upstream.
All HF output signals from the modules are combined via the inputs of the
active HF output collector and prepared for distribution through the HF output
socket.
When the head-end station is shipped from the factory, the default setting for
the output level of the HF output collector is maximum. Please set the master
output level to the value required for the respective cable system.
When the head-end station is switched on, the two-line LC display shows the
“SETUP” menu and the software version of the control unit. The head-end
station output level can be adjusted in this menu.
The operating software for the control unit and modules can be updated via
the 9-pin SUB-D socket of the head-end station using a PC or notebook and
the software “BE-Flash”. Current versions of the software can be found by
your FUBA distributor (www.fuba.com).
