2. Installation and connection
The SKT 40-00 can be operated either in a headend base unit SKS x0-xx or in the stand-alone mode with the
external power supply unit (SKZ 5-03). In both cases, all elements must be installed in a voltage-free condition.
The SAT IF inputs can be connected directly to a quattro LNB or to a SAT IF distributor. The plugged cable of
the headend supplies the unit with power. The input distribution can also be done via a standard multiswitch
with up to 16 SAT IF levels.
2.1.
Installation and connection in a headend base unit
Every slot in the base unit has a fixing screw in order to install the headend modules. Before the installation,
the upper screw must be loosened. When being attached to the output combiner, the module is at the same
time mounted on the loosened screw. Please tighten then the screw well.
Please pay attention to the maximum number of modules which can be supplied by the power
supply unit (see section 2.1.1 on page 10).
The modules have two identical connecting sockets on the bottom for the power supply. Both are linked
together internally.
One of both connecting sockets is used to get the operating voltage from the power supply unit or from
another module.
The second one can be used to loop the operating voltage through to the next module or to the output
combiner of the base unit.
With the DC patch cable (SKZ 40-00) included in the scope of delivery, the modules can be connected together.
While looping the modules through, a maximum of 3 x SKT 80-xx or 4 x SKT 40-xx can be connected
together.
Installation in the headend base unit SKS 4-01:
The power supply unit SKZ 5-01, integrated in the headend base unit SKS 4-01, has a DC connecting cable on
the output side. This cable is connected to the first SKT 40/80 module.
The other modules are connected to each other using the enclosed DC connecting cable SKZ 40-00.
A separate DC connecting cable SKZ 40-01 is additionally required to supply the output combiner. Connect the
output combiner to the last module. The connecting cable SKZ 40-01 is not included in the scope of delivery.
Installation in the headend base unit SKS 8-00:
The power supply unit SKZ 6-00 integrated in the headend base unit SKS 8-00 has a short and a long DC
connecting cable on the output side. Connect the short DC connecting cable to the first SKT 40/80 module and
the long DC connecting cable to the fourth SKT 40/80 module.
The other modules are connected to each other using the enclosed DC connecting cable SKZ 40-00. Two
separate DC connecting cables SKZ 40-01 are additionally required to supply the output combiner.
Connect the output combiner to the last module on the right and to the third module on the left side. The
connecting cables SKZ 40-01 are not included in the scope of delivery.
