UMG 508Applying measurement currentThe UMG508 is designed for the connection of../1A and ../5A current converters.Only AC currents, and not DC currents, can bemeasured using the current measurement inputs.Short-circuit all current converter outputs exceptone. Compare the currents displayed bythe UMG508 with the applied current.The current displayed by the UMG508 mustmatch the input current under consideration ofthe current converter transfer relation.The UMG508 must display approx. zero amperesin the short-circuited current measurementinputs.The current converter ratio is set to 5/5A in thefactory and may have to be adapted to the currentconverter used.Voltages are shown with long pointers in thepointer diagram, and currents with shorterpointers.VoltageSignReactive power• positive (+) with inductive load,• negative (-) with capacitive load.Phase angle (U/I)• positive (+) with capacitive load,• negative (-) with inductive load.72mCurrentWarning!Voltages and currents outside of theauthorized measurement range candestroy the device.
