Due to its electrical isolation between the supply circ
4、uit and the measuring circuit, it can be supplied either by an external auxiliary voltage or by the supply voltage to be monitored. Insulation resistance faults are evaluated separately for L+ or L- and displayed by LEDs. Due to its measuring principle, the CM-IWN-DC is not able to detect balanced e
