ELECTRICAL CONNECTIONS 55.1 PRELIMINARY INFORMATIONThe characteristics of the electrical lines must be determinedby specialized personnel able to design electrical installationsin conformity with regulations in force.The protection devices of the unit power line must be able tostop the presumed short circuit current, whose value must bedetermined in function of system features.The power cables and the protection cable section must bedefined in accordance with the characteristics of the adoptedprotections.All the electrical operations must be performed by qualifiedpersonnel as required by the regulations in force, educatedon the risks related to these operations.Operate as required by the safety regulations in force.5.2 ELECTRICAL DATAThe serial number label reports the unit specific electricaldata, included any electrical accessories.The electrical data indicated in the technical bulletin and in themanual refer to the standard unit, accessories excluded.Refer to the electrical data report on the serial number label.5.4 SIGNAL LINES/DATA-LAYDo not overpass the maximum power allowed, which varies,according to the type of signal.Lay the cables far from power cables or cables having adifferent voltage and that are able to emit electromagneticdisturbances.Do not lay the cable near devices which can generateelectromagnetic interferences.Do not lay the cables parallel to other cables; cable crossingsare possible, only if at 90°.Connect the screen to the ground, only in case of nodisturbances .Guarantee the continuity of the screen for the entire extensionof the cable.Respect impendency, capacity and attenuation indications.5.5 ELECTRIC LINE INPUTserial numberlabelVOLTAGEFLA (A)FLI (kW)Fix the cables : if vacated they may be subject to tearing.F.L.A. full load ampereFull load current at max admissible conditionsF.L.I.Full load inputFull load power input( at max. admissible condition )The cables must not touch the compressors and therefrigerant piping (they reach high temperatures)5.3 CONNECTIONS1. Refer to the unit electrical diagram (the number of thediagram is shown on the serial number label)2. Verify that the network has characteristics conforming tothe data shown on the serial number label3. Before starting work, verify that the sectioning device atthe start of the unit power line is open, blocked andequipped with sign warning4. First create the earthing connection5. Shelter the cables using adequate measure fairleads6. Before powering the unit ensure that all the protectionsthat were removed during the electrical connection, havebeen restored.11
