Page 13: Intended Use
Safety instructions 2.3 Intended use The ISOMETER® of the isoEV425 or isoEV425HC series monitors the insulation resistance R of unearthed AC/DC main circuits (IT systems) with nominal sys- tem voltages of 3(N)AC, AC/DC 0 … 690 V or DC 0 …1,000 V. The main appli- cation areas are unearthed DC charging stations (mode 4 acc. -

Page 15: Functional Description
Function 3.2 Functional description The ISOMETER® measures the insulation resistance R and the system leakage capacitance C between the system to be monitored (L1/+, L2/-) and earth (PE). The RMS value of the nominal system voltage U between L1/+ and L2/- as well as the residual voltages U (between L1/+ and earth) and U (be-... -
Page 16: Monitoring The Insulation Resistance
Function If the values R or U do not violate their release value (response value plus hysteresis) for the period t without interruption, the alarm relays will switch back to their initial position and the alarm LEDs "AL1"/"AL2" stop lighting. If the fault memory is activated, the alarm relays remain in alarm condition and the LEDs light until the reset button "R"... -
Page 17: Self Test/Error Codes
Function 3.2.3 Self test/error codes The integrated self test function checks the function of the insulation moni- toring device, and connection monitoring checks the connections to the sys- tem to be monitored. The alarm relays are not switched during the self test. This can be changed using the parameter "test"... - Page 18 Function The maximum permissible system leakage capacitance is exceeded Action: E.07 Device not suitable for the existing system leakage capaci- tance: uninstall device. Calibration error during device test Action: E.08 If the error continues to exist after checking the device con- nections, there is an error inside the device.

Page 20: Measuring And Response Times
Function sages "-R1" and "-R2" indicate an insulation fault assigned to conductor L2/-. If an assignment is not possible, for example in the event of a symmetrical insu- lation fault, the messages corresponding to "+" and "-" are shown together. The message "test"... - Page 21 Function Operating time The operating time t is the time required by the ISOMETER® to determine the measured value. The insulation resistance measured value depends on the insulation resistance R and the system leakage capacitance C . High sys- tem leakage capacitances and system interferences lead to longer operating times.
