Installation And Safety Instructions - Kathrein EXR 1541 Handbuch

Installation and safety instructions

• The equipment described is designed solely for installation in 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 areas indoors. Do not mount it on or against easily fl ammable
materials.
• The equipment must be provided with an equipotential bonding wire (Cu, at least 4 mm2).
• 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.
• In order to satisfy the EMC requirement, the only power supply unit that may be used for the EXR 1541 is
the NCF 18.
• Unused RF connections must be terminated with 75-Ω resistors (such as EMK 03).
Current-carrying device NCF 18
• Do not open the unit or tamper with it!
• When working on the system always unplug the power supply unit 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. Danger of overheating!
• Ambient temperature range -20 to +55°C
Caution:
• 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.
• In order to disconnect the unit from the mains it is necessary to unplug it at the wall socket, which must
therefore be easily accessible.
• An inner cable conductor dia-
meter greater than 1.2 mm, or
the presence of burrs may da-
mage the sockets on the unit.
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 may be performed manually or automatically.
• It is recommended that the wall sockets with the shorter length connections are assigned to the higher
frequencies.
• By defi nition the system is designed so that single-cable units 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 trans-
mitted. 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.
