3. Remove approx. 10 mm of the inner plastic insulation (approx. 5 mm of the insulation
remains in a place).
4. Carefully screw the F connector on the cable end until the plastic insulation levels with
the F connector opening.
5. Check there is no short between the inner conductor of coaxial cable and F connector.
The coaxial cables shall not be broken, the minimum bending radius should be 5 cm. Connect the
F connectors into the F sockets of product and fasten them with an appropriate force.

Connect input F socket marked TERR IN with output of terrestrial antenna, eventually
with output of terrestrial antenna with terrestrial antenna preamplifier.
•
Connect output F sockets marked 1 to actual number of outputs of multiswitch with
other components in distribution system (satellite receiver, terrestrial receiver, wall
socket etc.).
•
Connect connector marked with protective bounding symbol with protective bounding
conductor, see section 10 Symbols Explanation.
•
Connect the mains plug into the mains socket with voltage according to section 2
Technical Specifications.
In case when quad LNBs are used, it is necessary to switch on 22 kHz, see section 6 Product
Settings. If some of outputs are not used, it is appropriate to terminate them with 75 Ohm loads. If
not terminated, insertion loss curve in terrestrial band may be rippled.
The wiring examples are shown in the section 11 Wiring Diagrams or at the website www.emp-
centauri.eu.
6 Product Settings
For all SAT inputs, it is possible to change level of signals by means of attenuators in 15 dB
range. The minimum attenuation is in clockwise stop position, the maximum attenuation is in
counterclockwise stop position (for terrestrial input switching to passive mode, see below). Set
attenuators very gently, do not turn them behind stop positions by force.
22 kHz signal can be switched on / off by DIP switch located at right low side of the multiswitch.
•
Lever 4 controls 22 kHz at satellite inputs C & D (OFF: enabled, ON: disabled)
•
Lever 3 controls 22 kHz at satellite inputs G & H (OFF: enabled, ON: disabled)
•
Lever 2 controls 22 kHz at satellite inputs K & L (OFF: enabled, ON: disabled)
The lever is in ON position when closer to upper side of the multiswitch. The lever is in OFF
position when closer to lower side of the multiswitch. Lever 1 is the closest to the multiswitch
power supply.
Active and passive mode of terrestrial band can be selected by turnable switch, passive mode is
selected by turning the switch to counterclockwise stop position. The return path is available in
the passive mode.
If input F socket marked TERR IN is in short connection or maximal allowed current is exceeded
(see section 2 Technical Specifications), the voltage decreases down near to 0 V. Quality of
signals is not affected however.
Satellite receiver must be set up according to following table:
LNB
DiSEqC command for
switching to given LNB
receiver set up
LNB 1
Position 0 + Option 0
DiSEqC 1 or DiSEqC A (according to receiver)
LNB 2
Position 1 + Option 0
DiSEqC 2 or DiSEqC B (according to receiver)
LNB 3
Position 0 + Option 1
DiSEqC 3 or DiSEqC C (according to receiver)
7 Safety
Due to security reasons the product and wiring in which the product is connected, must be
grounded properly. Use the terminal identified with the appropriate symbol to ground the
product. Make sure the antennas are grounded properly.
Connect all devices to power grid only after all connections are finished and checked.
The product works with the AC voltage, see section 2 Technical Specifications. Make sure,
that the local AC voltage corresponds to the operating voltage of product.
No objects can be placed on the mains cord for prevent its damage or break. No hot objects
should touch the mains cord.
While disconnecting the product from power grid, never pull the mains cord but the mains
plug to prevent the mains cord damage. Pay attention that the mains plug holds tight in the
mains socket. Loose mains plug or mains socket means the danger of fire.
Never disassemble the product connected to the power grid, you risk the danger of electrical
shock.
Never work on the wiring (including satellite and terrestrial receivers, TVs) during or
before a storm. A lightning stroke into the antenna may cause dangerous overvoltage in the
product metallic parts.
The product should be disconnected from the wiring immediately if it gets into contact with
liquids (dropping water, spilled drinks etc.).
