1.Switching Power Supply Usage Notes:
1)The metal casing of the power cord is generally connected to the ground (FG), which should be securely grounded for safety purposes. It is important not to mistakenly connect the casing to the neutral line.
2)Before powering on and conducting a trial run after installation, please once again inspect and check the connections on the terminal strips to ensure that the inputs and outputs, AC and DC, single-phase and multi-phase, positive and negative poles are correctly connected.Voltage value andOnly when the current value is correct and unquestionable can the operation be conducted.
For high-power power supplies, there are generally three or more '+' input terminals and '-' output terminals, which actually belong to the same output polarity. This is done for the convenience of the user.
