Notes
(1) Before power supply, carefully check whether the voltage of the power supply meets the requirements;
(2) Pay attention to electrostatic protection when using in a dry environment;
(3) The recommended operating ambient temperature should not exceed 40℃;
(4) Be careful not to use excessive force when plugging or unplugging interfaces;
(5) Pay attention to the sequence of switching on the power supply and setting parameters;
(6) Good heat dissipation must be ensured during use.
