Considering placement of the data block in ODU, the station ZENITH 24 has an indoor unit reduced to the protected terminal box ALS1GEth (RP) or ALS12GEth (RP) that ensures transmissionofcustomerdata,poweringofthestation,andprotectionagainsttheatmospheric origin overvoltage and overcurrent. (The protected terminal box is marked as ALS1x in the furthertext.) ODU can be connected to the microwave parabolic antennas of the types ALCOMA AL1xx/ME,

(0.35m),AL2xx/ME(0.65m),AL3xx/MP(0.90m),andAL4xx/MP(1.20m).Theseantennasare standard equipped by icing protection (OPN) for use in demanding climatic conditions.

Themechanicaldesignoftheprotectedterminalboxassumesinstallationintoa19"rack.Thedesign allows sufficiently flexible arrangement of outputs without additional mechanical adjustments. The protected terminal box allows to bring the connection cable withODU to the front, or back panel. Customer data and the power supply can be brought to the front panel only. The arrangement can be modified according to customer wishes, and it is possible to deliver an arrangement that will suit the station,whileitnotnecessarytohavetheoutputsidenticallyarrangedinabox.

Activity of the ODU supply is indicated by the green LED placed on the mother boardinthespaceoftheuserterminalbox.Monitoringdataareaddedtotheuserline(Line3+mgmt)in theoutdoorunit(ODU). The high frequency block of the ZENITH 24 link consists of a microwave receiver, transmitter, microwaveoscillatorsandothersupportcircuits. Microwave oscillators generate signals for mixers in the receiver and transmitter.

SETTINGOFTHERADIOLINKANDITSCOMMISSIONING Installation and commissioning of the radio relay ZENITH 24 radio link can be performed by the manufacturerorbyacompanyauthorizedbyhimonly.Theinstallationcanbeperformedbyconnectingto apower grid, whose technical condition and manner of protection against electric current injury meets conditions of the SN 33 2000441 standard and related regulations. The user must verify whether the ODUsupplyvoltageagreeswiththeoutputvoltageofapowersupply.Electricpowernetwork,towhichthe productwillbeconnected,mustbeinitiallyinspectedaccordingtotheSN3320002000661standard.If usingofextensioncablesisabsolutelynecessary,thenthesecablesmustberoutedinthewaythatwould preventtheirdamage,overheating,orpossibleinjuriestopersonnel(bytripping). Forreasonsofachievinghighoperationalreliability,parameterstabilityandlonglifetheunits(even enclosedinacabinet)maynotbeplacednearheat,water,dust,orvibrationsourcesetc. The ALCOMA ODU units do not contain any adjustment or tuning elements that would have to be modified during commissioning by customers. The units are delivered tuned and tested. Removal of possible defects and failures within the warranty period is done by the manufacturer or a company authorized by the manufacturer. Any manipulation with adjustment elements is prohibited. Any unprofessionalinterferencewiththeequipment,especiallymanipulationwithadjustmentelements,voids thewarranty. CAUTION Anoutdoorunitandaprotectedterminalboxmustbeproperlyconnectedtoaprotection cable, and grounding must be performed due to atmospheric electricity charges. (SN 33 4010Communicationlineandequipmentprotectionagainstatmosphericovervoltageand overcurrent). Changing of jumpers in ALS1GEth or ALS12GEth can be done only by personnel instructed at the manufacturer. In case of commissioning after long term storage (in order of months) the actual time needs to be checkedabout10minutesafterswitchingon.Dataarebackedupbyahighcapacitycapacitor. 4.1 ANTENNAPOINTING Pointing of radio link is done by adjusting antennas to the maximum level of received signal.
