Installation and safety instructions
• The equipment described is designed solely for the installation of satellite receiver systems.
• Any other use, or failure to comply with these instructions, will result in voiding of warranty cover.
• The equipment may only be installed in dry indoor areas. Do not mount on or against highly combustible
materials.
• The equipment must be provided with an equipotential bonding wire (Cu, at least 4 mm
• The safety regulations set out in the current EN 60728-11 and EN 60065 standards must be complied with.
• Fixings: Wood screws, max Ø: 4.5 mm
• Connector: RF plug 75 Ω (series F) to EN 61169-24.
• Unused RF connections must be terminated with 75 Ω resistors (e.g. EMK 03).
Current-carrying device EXR 1942
• Do not open or tamper with the unit!
• When working on the system always unplug the mains plug from the wall socket!
• Ensure adequate clearance! Clearance all round at least 5 cm!
• The unit must not be mounted on the ceiling!
• Free circulation of air must be possible to discharge the heat emitted by the unit. Risk of overheating!
• Permissible ambient temperature -20 to +55°C
Important:
• No liquid-fi lled items may be placed on top of the power supply unit.
• The power supply unit must not be exposed to dripping or splashing water.
• The mains plug must be easily accessible and operable.
• The only reliable method of disconnecting the unit from the mains is to unplug it.
• If the inner cable conductor diameter is greater than 1.2 mm or in case of burr,
the device sockets may be destroyed.
Notes
• Particular care should be taken to assign each of the frequencies available at the output from the
multi-switch to only a single receiver, otherwise the receivers will generate mutual interference.
• The frequencies are allocated on the receiver's setting menu.
• Depending on the type, this assignment may be manual or automatic.
• It is recommended that the outlets with the shorter length connections are assigned to the higher
frequencies.
• By defi nition the system is designed so that single-cable devices are supplied with 14 V DC.
• The power supply is briefl y switched to 18 V DC if control signals similar to DiSEqC™ have to be
transmitted. Continuous application of 18 V would block the system. For this reason we recommend
the use of ESU 33/34 sockets, which are equipped for switching off electronically.
• The receivers that are connected must be designed for single-cable operation to EN 50494.
