1 notes about s afet y and ha z ards
• The head-end station is subject to the regulations of protection class I.
• Never operate the device without a protective earth connection, earth con-
nection to the device and potential equalisation!
• The standards EN/DIN EN 50083-2 resp. IEC/EN/DIN EN 60728-11 must
be observed.
• Observe the relevant country-specific standards, regulations and guidelines
on the installation and operation of antenna systems.
• Replace mains cable and power supply unit only by original spare parts.
• 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.
• The device should only be installed in a room where the permissible am-
bient temperature range of 0°C…+50°C can be maintained, even during
fluctuations in climatic conditions.
• To avoid too strong heating of the head-end station it is not admissible to
mount them one upon the other without using thermic precautions (e.g.
permanently air recirculation, ventilation, heat deflectors etc.).
• Do not install the device in cabinets or recesses which are not ventilated.
• 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.
• In case of the formation of condensation wait until the system is completely dried.
• Do not cover the ventilation openings!
• During installation, observe a minimum distance of
- 500 mm above/below and 75 mm behind the device at wall mounting,
- 500 mm above and 75 mm below/behind the device at upright mounting,
- 200 mm above/below and 100 mm behind the device at mounting in a
19" cabinet.
• 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 wa-
ter and dampness
- Where it is protected from direct exposure to sunlight
- Not within the immediate vicinity of heat sources
• Do not place any vessels containing liquids on the device.
• Do not place anything on the head-end station which could initiate fires
(e.g. candles).

- 4 - STC 160
• Due to the risk of fires caused by lightning strikes, we recommend that all me-
chanical parts (e.g. distributor, equipotential bonding rail, etc.) be mounted
on a non-combustible base. Wood panelling, wooden beams, plastic cov-
ered panels and plastic panels are all examples of combustible bases.
• Avoid short circuits!
• 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 inap-
propriate handling of the device.
Take precautions to prevent static discharge when working on the device
and the modules!
Electronic devices should never be disposed of in the household rubbish. In
accordance with directive 2002/96/EC of the European Parliament and the
European Council from January 27, 2003 which addresses old electronic and
electrical devices, such devices must be disposed of at a designated collection
facility. At the end of its service life, please take your device to one of these
public collection facilities for proper disposal.

2.5 desC r i p t i on
Proper installation of the mounting bracket enables the STC 160 head-end sta-
tion to be installed in a 19" cabinet as well as on a wall or upright standing.
The head-end station is modular in design and can be equipped with 8 stand-
ard plug-in modules and 8 add-on modules. A current list of the standard and
add-on modules can be found on the website "www.mygss.eu". 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 and an output collector can be upgraded to offer the
highest degree of flexibility for the distribution of the signals.
The power supply in the STC 160 head-end station is designed to supply
power to components (e.g. LNB) connected upstream.
All RF output signals from the modules are combined via the inputs of a retro-
fitted active RF output collector and prepared for distribution through the RF
output socket.
When the head-end station is shipped from the factory, the default setting for
the control voltage for a RF output collector is maximum. If necessary 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 sta-
tion output level can be adjusted in submenu "OUTPUT", the output standard
can be adjusted in submenu "NORM". Set a 4-digit PIN in menu "PIN" to
protect the control panel from unauthorized access.
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 on the
website "www.mygss.eu".

– Install the head-end station vibration-free.
Avoid, for example, mounting the head-end station onto a lift shaft or any
other wall or floor construction that vibrates in a similar way.
– To avoid too strong heating of the head-end stations it is not admissible
to mount them one upon the other without using thermic precautions (e.g.
permanently air recirculation, ventilation, heat deflectors etc.).
– Using the supplied mounting brackets, the head-end station can be mounted
to a wall, upright standing, or in a 19" cabinet. Before proceeding, ensure
that the minimum distance requirements (500 mm above/below and 75
mm behind the device at wall mounting / 500 mm above and 75 mm be-
low/behind the device at upright mounting / 200 mm above/below and
100 mm behind the device at mounting in a 19" cabinet) will be met.
– If mounting to a wall or on a shelf, ensure that ...
- The wall or the shelf can support the weight of the head-end station
- There is adequate air conditioning
- The permissible ambient temperature will be maintained
– If mounting inside a 19" cabinet, ensure that ...
- there is adequate air conditioning.
- the permissible ambient temperature will be maintained.
- the mounting rack in the cabinet can support the weight of the head-end
station.
Note:
To maintain an ambient temperature of < 50 °C, use an additional fan or a
safety temperature limiter with reclosing interlock if necessary.
