1 notes about safe t y and hazards
• 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.
• Do not perform installation and service work during thunderstorms.
• Assembly, installation and servicing must be carried out by an authorised
electrician.
• 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 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.
• Do not cover the ventilation openings!
• Do not install the head end in cabinets or recesses which are not ventilated.

- 5 - PSU 8-16 A
• 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 Profi
cassettes. You can find a list of the current Profi cassettes at the website
"www.mygss.eu". This head-end station is designed exclusively for use with
cassettes of the Profi marketing programme. The various expansion options for
the head-end station allow for the installation of a wide range of broadband
cable systems.
Two integrated SAT IF input distributors has in total four SAT IF inputs. You can
use them to distribute the reception levels each over 4 or 6 outputs. Using the
loop-through output enables you to distribute reception level 1 over the 10
outputs for each SAT IF input distributor. The F sockets of both reception levels
are coloured.
Basic signal pattern:
9-12 dB 9-14 dB
8 dB
Unused loop-through outputs must be terminated with the resistors supplied.
The power supply in the head-end station is designed to supply power to com-
ponents (e.g. LNBs) connected upstream. These are supplied via the SAT IF
input distributors’ input sockets with operating voltage (+18 V) at a total cur-
rent of max. 1 A .
The head-end station’s power supply unit can be used to supply peripheral
devices with voltage (+12 V / max. 1 A , with an external fuse).
The cassettes’ RF output signals are accumulated in a programmable RF output
collector and then directed to the RF output and to the test output via the down-
stream hybrid amplifier.

- 9 - PSU 8-16 A
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.
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.
The display also supports dialogue guidance when programming the head-
end station. Use the buttons of the control unit to program the head-end sta-
tion. You can also use the PSW 1000 software and the PRCU 8 / RCU 1 /
PRCU 12 management unit to program 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".

4.1 emC r eG ul ati o ns (electro magn e t i c Com pat i bi l it y )
To comply with the current EMC regulations, it is necessary to connect the lines
leading in and out of the head-end station (e.g. Cinch, RF) using standard ca-
ble terminals.
Fig. 8
• According to figure 8 insert the required number of standard cable termi-
nals in the openings provided in the front of the head-end station (fig. 2 5,
page10).
Tighten the nuts on the cable terminals until the teeth on the lock washers have
penetrated the exterior coating and a good connection is made between the
housing and the cable terminals.
—> To maintain compliance with the EMC regulations, the head-end sta-
tion must not be operated without the front cover.

– 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.

mou nt i nG in a 19" C ab inet
The head-end station has been designed for installation into 19“ rack systems.
—> The total installation height of a 19“ unit is 9 HU (39.7 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.
