Reactive Power Controller Operating instructions

Reactive Power ControllerInstallation and putting into serviceMeasurement and supply voltageThe controller Prophi can be delivered in two connectionvarieties for the measurement and supply voltage.In the version measurement L-L, the measurement andsupply voltage must be taken from two outer conductors.In version measurement L-N, the measurementand supply voltage must be taken between outer conductorL and neutral N.Before connection, please ensure, that the local net conditionsmatch the data on type plate. The range of themeasurement and supply voltage is given by the typeplate and is connected via a fuse (2…10A, time lag type)Attention!The measurement and supply voltage mustcome from the low voltage net, which is supervised.The connected measurement and supply voltage maynot exceed the voltage, mentioned on type plate formore than 10% or underscore for more than 15%.To ensure, that the connected measurement and supplyvoltage is within the allowed range, please check thevoltage at the terminal with a voltmeter.Attention!Voltage, which is out of the indicated rangeon type plate can destroy the instrument.ProphiL1L2L3PEMessungMeasurementL/Lsiehe Typenschildsee type label0,01 .. 5Akk l L2 L3l../5(1)A2 .. 10AVerbraucherConsumerDiagr.: Connection of measurement and supply voltage(L2-L3) and current transformer.If the measurement and supply voltage is within theallowed range, Prophi indicates the voltage on the terminal.While measuring via voltage transformers, the voltagetransformer ratio must be programmed. Attention!The operating voltage for the contactors shouldbe received from an outer conductor connectedto the controller.Diagr.: Connection of measurement and supply voltage(L1-N) and current transformer.Page 10= Key 1 = Key 2 = Key 3
