If you change the Network type during ongoing operation, check settings, measured values, and limiting
values for inconsistencies. Check also the ICD/IID file which is suitable for the network type. If there are any
invalid measured values and limiting values or a wrong ICD file, restart the device.
Once you enable the voltage transformer, the parameter Voltage transformer is invisible on the HTML page. If you want to disable
6
the voltage transformer, you can set the same value for Primary rated voltage and Secondary rated voltage.
If you upgrade your firmware to V02.60, and want to set this parameter to the value from 1.0 V to 99.9 V, you must get the default
7
configuration firstly.
8 This parameter is to define whether the current direction is the same as the physical connection.
