1 notes about safe t y 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 con-
nection to the device and potential equalisation!
• Observe the relevant VDE regulations.
• If the power cord needs to be replaced, only use an OEM power cord (EMC).
• The standards EN/DIN EN 50083 resp. IEC/EN/DIN EN 60728 must be
observed, especially concerning equipotential bonding and earthing .
• Observe the relevant standards, regulations and guidelines on the installa-
tion and operation of antenna systems.
• Before starting installation or service work disconnect the receiving system
from mains. For a complete disconnection from the mains, the mains plug
must be pulled out of the mains socket. Ensure that the mains plug can be
pulled out without difficulties.
• Do not perform installation and service work during thunderstorms.
• Assembly, installation and servicing must be carried out by an authorised
electrician.
• The head-end station should only be installed in a room where the permissi-
ble ambient temperature range (0 °C and +50 °C ) can be maintained, even
during fluctuations in climatic conditions.
• Make sure there is a minimum space
- at wall mounting 50 cm above and below
- at mounting in a 19" cabinet 20 cm above and below, as well as 10 cm
behind.
• 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.).
• 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.
• Install the head-end station
- 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
- on a vibration-free wall or floor construction
- not within the immediate vicinity of heat sources
• In case of the formation of condensation wait until the system is completely
dried.
• Ensure that the head-end station is adequately ventilated.

- 5 - STC 816 R
• Do not cover the ventilation openings!
• Do not install the head end in cabinets or recesses which are not ventilated.
• Do not place any vessels containing liquids on the head-end station.
• Do not place anything on the head-end station which could initiate fires
(e.g. candles).
• 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 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.
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 desCri p ti on
The head-end station has a modular structure and can hold up to 8 Standard
cassettes. You can find a list of the current Standard cassettes at the website
"www.mygss.eu". This head-end station is designed exclusively for use with
cassettes of the Standard marketing programme. The various expansion op-
tions for the head-end station allow for the installation of a wide range of
broadband cable systems.
The redundant power supply consisting of 2 complete power supplies in half-
load operation, enables e.g. a UPS and mains operation or a 2-phase opera-
tion. Both power supplies are individually hot swappable. In case of failure of
a power supply, a warning tone sounds. One LED per power supply lights
green during fault-free operation and red when the output voltage is faulty or
overheating / a fan failure is present. The head-end station is designed to sup-
ply power to components (e.g. LNBs) connected upstream. The head-end sta-
tion’s power supply unit can be used to supply peripheral devices with voltage
(+12 V / max. 1 A , with an external fuse).
By retrofitting two input distributors, 2x2 SAT IF inputs can be distributed to 2
x (4 + 6) outputs.
The cassettes’ RF output signals are accumulated in a programmable RF output
collector and then directed to the RF output. When the head-end station is
shipped from the factory, the default setting for the RF output level of the output
collector is -3 dB. You can use the software of the control unit to program the
master output level of the head-end station.
The software version of the control unit appears on the two-line LC display after
switching on the head-end station. The display also supports dialogue guid-
ance when programming the head-end station. Use the buttons of the control
unit to programme the head-end station. You can also use the PSW 1000 soft-
ware and the HRCU 8 / RCU 1 management unit to programme the head-end
station.
The RS 232 interface of the control unit enables you to use a PC or a note-
book and the "BE-Flash" software to update the operating software of the
control unit. You can find the current operating software for the control unit,
the software "BE-Flash" and the current assembly instructions on the website
"www.mygss.eu".
If the inner temperature of the head-end station exceeds the permissible tem-
perature of 65 °C when operating, a message appears in the display instead
of the standby menu. This message contains the maximum measured tempera-
ture and the number of the head-end station.

4.2 mou n t i nG th e h ead-en d s tation
– 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.).
– Ensure that
- the mounting area can support the weight of the head-end station
- there is an adequate ventilation
- the permissible ambient temperature will be maintained
- the mounting position is dry and protected against splashing water.
—> For a complete disconnection from the mains, the mains plug must
be pulled out of the mains socket. Ensure that the mains plug can be
pulled out without difficulties.

The head-end station has been designed for installation into 19“ rack systems.
—> The total installation height incl. the free space to change a power
supply unit is 14 HU (62 cm, hole spacing 26.5 cm).
In cabinets a circular aeration (e.g. by means of ventilators) is to
be ensured. If the maximum ambient temperature inside the cabinet
exceeds +50 °C, a thermo switch with reclose inhibition must auto-
matically disconnect the system from the mains power supply.
• Position the head-end station in the cabinet so that there is a minimum free
space of 20 cm above and below, as well as 10 cm behind.
