3.2. LNB Power Supply
The power supply of the LNBs is performed by means of the power supply unit at the
multiswitch. A maximum of 600 mA per LNB is available to feed the LNBs
=> Max. 1,2 Ampere are available for power supply of the LNBs.
3.3 Low energy consumption
If all connected satellite receivers are turned off, the multiswitch enters a
power saving standby mode, where the LNB supplies and the satellite
amplifiers are disabled. The LNBs are not supplied with power unless at least
one of the receivers is switched on. The terrestrial reception with its amplifiers is not
affected.
3.4. System Cabling
- T3.4 The system must have a star-topology distribution structure from the multiswitch to
the antenna sockets (e.g. Schwaiger DSE 650 or DSE 652) , i.e. only one receiver may be
connected to each output on the multiswitch. For twin receivers you need two supply lines.
- Use 75 Ohm coaxial cables for system cabling (e.g. Schwaiger KOX 110).
- Subsequent to mounting the F connectors, check the coaxial cables for short circuits.
3.5. All unused inputs and outputs of the multiswitch should be terminated capacitively separa-
ted 75 Ohm matching resistors (e.g. Schwaiger ÜST 8380 201).
3.6. Mounting of the Multiswitch
Multiswitches must only be installed in dry rooms with sufficient ventilation.
Moreover, multiswitches must be mounted to a hardly flammable ground.
IMPORTANT:
During constant operation at 25°C room temperature, some parts of the multiswitch carry a
temperature of up to 55°C, depending on the current input of the LNB type used.
3.7. Protective Arrangement
The multiswitch needs to be grounded by way of its grounding terminal!
