Additional setup parameters for IM20

You need to configure the IM20 in order to display ZC impedance and for operation in a higher-voltage power system.

ZC impedance display

In order to calculate the ZC value, the frequency of the power system must be configured. The accepted values are DC (for a DC power system), 50 Hz, 60 Hz and 400 Hz. The default value is 50 Hz.

High-voltage operation

When used in a power system exceeding 480 Vac or 345 Vdc with a high voltage adapter (IM20-1700), parameter Adapt. V. must be set in HV1700. The default value is Sans (operation without an adapter and in a power system below 480 Vac or 345 Vdc).
