HOW TO USE: 1. Place the automatic transfer switch of the dual power supply on the debugging platform, andconnect the corresponding power line according to the correct phase sequence. The phase line andthe neutral line are connected in position, and the wrong connection is not allowed.3. When debugging the three-pole switch, the common and spare neutral wires should be connectedto the neutral terminal (NN and RN) respectively.3. Set the dual power supply automatic transfer switch to work in the self-turning and self-resettingmode. If the voltage of the two power supplies is normal, the switch should be placed in the commonpower supply position, and the common power supply is closed.4. Set the common power supply NA, NB, NC, NN for any phase loss, the dual power supply shouldbe automatically converted to the backup power supply, if the common power supply returns tonormal, it should be converted back to the common power supply5. Adjust the voltage of any phase of the common power supply to the predetermined undervoltagevoltage value, and the dual power supply should automatically switch to the standby power supply.When the normal power supply returns to normal, the switch should return to the normal powersupply
