2 Safety Hints
For your own protection, you should read the safety hints carefully before installing the
GigaSwitch multiswitch. The manufacturer accepts no responsibility for damage caused by
non-observance of the safety hints, or by inappropriate handling.
> The components must be mounted in dry rooms on flat, non-flammable surfaces.
> Air circulation slots on the components must permit unimpeded circulation.
> The installation must be carried out while the unit is not connected to the power
mains.
> The multiswitch must be connected to ground (earthed).
> The antenna installation must comply with local regulations relating to lightning pro-
tection.
> The relevant EU standards as well as VDE or national regulations relating to electrical
safety must be observed.
> National regulations relating to broadcast reception equipment must be observed.
> Never open the unit cover, as you may be subject to an electrical shock!!!
> If it becomes necessary to open the unit, this should only be carried out by trained
personnel.
In the following cases, you should disconnect the unit from the power mains, and call an

3 Introducing the components
3.1 GigaSwitch 11/20G (Part No. 0000/3229)
The GigaSwitch 11/20G is the basic unit in the multiswitch range. The GigaSwitch 11/20G
provides distribution of the Intermediate Frequency signal to 20 participants, including provi-
sion of power to the LNBs. In larger installations it also provides the power for the cascade
multiswitch GigaSwitch 11/20K, for the distributor 9V and for the intermediate amplifier 9Z.
When installing a cascade system of several components, please ensure that the maximum
power voltage is not exceeded (see technical specifications).
3.2 GigaSwitch 11/20K (Part No. 0000/3228)
The GigaSwitch 11/20K is the cascade unit in the multiswitch range. This unit receives its
power supply from the basic unit GigaSwitch 11/20G. The GigaSwitch 11/20K unit can thus
only be used in conjunction with the basic unit. The GigaSwitch 11/20K is inserted between
the LNBs and the basic unit, with each additional 11/20K unit providing connections for 20
participants.
The function of the cascade is to distribute the eight polarisation planes as well as the terre-
strial signal further along the main connection, and to provide up to 20 participants with inde-
pendent access to the selected band.
