Insulation monitoring device for unearthed AC, AC/DC and DC systems (IT systems) up to 3(N)AC, AC 400 V, DC 400 V Suitable for the application of generators acc. to standard DIN VDE 0100-551 Product description The ISOMETER® monitors the insulation resistance of unearthed AC, AC/DC and DC systems (IT systems) with nominal system voltages of 3(N)AC, AC/DC 0…400 V or DC 0…400 V. The maximum permissible system leakage capacitance Ce is 5 μF. DC components existing in AC systems do not influence the operating characteristics, when a minimum load current of DC 10 mA flows. A separate supply...

If the values RF or Un do not violate their release value (response value plus hysteresis) for the period toff 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” is pressed or the supply voltage is interrupted. The device function can be tested using the test button “T”. Parameters are assigned to the device via the LCD and the control buttons on the front panel; this function can be...

Test / Reset If supplied from an IT system, both lines have to be protected by a fuse.* Connect each terminal separately to PE: The same wire cross section as for A1, A2 is to be used. L1/+, L2/– Connection to the IT system to be monitored T/R Connection for the external combined test and reset button. 11, 14 Connection to alarm relay K1 11, 24 Connection to alarm relay K2 A, B RS-485 communication interface with connectable terminating resistance. * For UL applications: Only use 60/75°C copper lines! For UL and CSA applications, it is mandatory to use 5 A fuses for the protection of the...
