The QI-50-I has two dip-switches through which you can set the scale to 25 or 50A and select the monopolar or bipolar (see charts), the yellow led near the terminal will indicate the presence of the power supply. If you are using bipolar function on AC current, the value read will be 0 A (12 mA) because you are reading the average value.
Any changes made by dip-switch required to switch off the power supply. It’s a safety condition in order to prevent any manumission on the device.
The current transformer QI can be mounted in any position (see photo below), horizontal or vertical mounting, horizontal or vertical through the two hooks for DIN rail included in the box.
