How to use:
1. Place the dual power supply automatic switch on the debugging platform and connect the corresponding power line in the correct phase sequence. The phase line and neutral wire are connected in position and wrong connection is not allowed.
3. When debugging the three-pole switch, the common and free neutral should be connected to the neutral terminal (NN and RN) respectively.
3. Set the dual power supply automatic switcher to work in self-rotation and self-reset mode. When the voltage of the two power supplies is normal, the switch should be placed in the position of the common power supply, and the common power supply should be closed.
4. Set the common power supply NA, NB, NC, NN for each phase loss. The dual power supply should automatically switch to the backup power supply. When the common power supply is back to normal, it should be switched back to the common power supply
5. Adjust the voltage of any phase of the common power supply to the predetermined undervoltage value, and the dual power supply should switch to the standby power supply automatically. When normal power returns to normal, the switch should return to normal power
