Safety instructions 2.3 Device specific safety information Danger as a result of excessive locating current or excessive locating voltage! An excessive locating current of the internal locating current injector may damage sensitive loads (e.g. control circuits) or trigger unwanted switching operations. Select a low locating current for these systems. -
Page 13: Address Setting And Termination
Safety instructions Unspecified frequency range! When connecting to an IT system with frequency components below the specified frequency range, the response times and response values may differ from the indicated technical data. However, depending on the application and the selected measurement method, continuous insulation monitoring is also possible in this frequency range. - Page 14 Safety instructions iso1685FR(M)_D00002_02_M_XXEN/06.2017...

Function • Commissioning: "chapter 5.3.2 Commissioning of the ISOMETER® iso1685FRM" • Modbus RTU protocol: "chapter 6.2 Device communication with Modbus RTU" 3.3 Functional description Insulation monitoring is carried out using an active measuring signal which is superimposed onto the IT system to earth via the integrated coupling. -
Page 17: Passive Method
Function is triggered. This function can be used to prevent the active process from being continuously interrupted, which in turn means that insulation errors could then be found. 3.3.1.2 Passive method Parallel to the active measuring method, a passive method is integrated for single-phase faults on the respec- tive live conductors (phases), which monitors the voltage between the neutral point of the IT network and earth. -
