——Wire Connection Modes——
Installation and wiring:
A, B, and C open-ended sensors are respectively clamped with A-phase, B-phase, and C-phase cables. At the same time, the three-phase voltages of A, B, and C are taken from the three-phase cable terminal, and the other 3 channels are the same as above, Then installation can be completed.
