What happens if I only connect the terminals but not Voltage?

If no voltage is connected, the current direction cannot be measured. If you only want to measure the consumption this is sufficient. However, a voltage of 230V (you can change this value at the settings page) is then assumed for the power calculation, which can lead to measurement tolerances
