Please use a power cord that meets the power requirements of this product.2. Before use, the power supply must be grounded reliably, and the weak leakage current caused by the internal anti‑electromagnetic interference circuit of the power supply should be led to the ground, otherwise "false leakage" will occur, which may cause damage to the load equipment or cause the power supply to resist interference Decrease in ability.3. When using this power supply to charge a reusable battery, make sure that the positive and negative poles of the power supply are correctly connected to the positive and negative poles of the battery. If they are connected reversely, the internal rectifier components of the power supply may be burned out or the load equipment may be damaged.4. It is strictly forbidden to use this product in an environment with flammable, explosive materials, humidity, and corrosive gas.5. When this product is working, it will generate heat, especially under full power usage. Therefore, please use this product in an environment with good ventilation and heat dissipation, and ensure that there are no other obstacles in the vicinity of the product's cooling fan and vents.6. When using this power supply, please select an output wire with sufficient wire diameter according to the output current of the product. The connection area between the wire and the power supply, the wire and the load equipment is large enough, the contact surface is clean and free of rust, and the connection must be firm to avoid heat damage to the terminal or load equipment, which may cause a fire in severe cases.
