UMG 508Current DirectionThe current direction can corrected on the deviceor individually using the available serial interfacesfor each phase.In the case of incorrect connection, subsequentreconnection of the current converter is not necessary.cCurrent converter connections!The secondary connections of the currentconverter must be short-circuitedto these before the electricity cablesare disconnected from the UMG508!If a test switch is available which automaticallyshorts the secondary currentconverter lines, it is sufficient to setthem to the "test" extradata, as long asthe short-circuiters have been checkedbeforehand.cOpen current converters!Extreme contact danger due to voltagepeaks can occur on current convertersthat are operated open on the secondaryside!For "anti-open current converters", thewinding isolation is calculated so thatthe current converters can be operatedopen. However, these current convertersare also dangerous to touch if theyare operated open.23
