How to Use:
1. Place the automatic transfer switch of the dual power supply on the debugging , connect the corresponding power line according to the correct phase sequence, and connect the phase line and the neutral line (zero line) according to the position, and the wrong connection is not allowed.
2. When debugging the two‑ and three‑pole switch, the common and spare neutral wires should be connected to the neutral terminal (NN and RN) respectively.
3. Set the dual power supply automatic transfer switch to work in the self‑turning and self‑recovering mode. If the voltage of the two power supplies is normal, the switch should be placed in the common power supply position, and the common power supply is closed.
4. Set the common power supply NA, NB, NC, NN for any phase failure, the dual power supply should be automatically converted to the backup power supply, if the common power supply returns to normal, it should be converted back to the common power supply.
