dC-2W dC-3W dC-4W 3P-3WY3
10. During the configuration step, the PEL automatically detects the connected current sensors. What is the exact order in which the terminals are checked?
I3, then I2, then I1. I1, then I2, then I3. All terminals are checked simultaneously. Only terminal I1 is checked, the others are ignored.
