When using the switching power supply, be sure to pay attention to the internal high voltage part of the machine, and do not touch the internal components of the machine. Non-professionals should not disassemble the power supply for maintenance, otherwise there is a danger of electric shock. Before use, read the relevant wiring marks 2. When wiring, please turn off the input power. 3. To ensure safe use and reduce interference, please ensure that the ground terminal FG is reliably grounded. (The grounding wire diameter is reasonably selected according to the input voltage and output power) 4. Check whether the mounting screws are in contact with the power supply board components, and measure the insulation resistance between the housing and the input/output to avoid electric shock. 5. Most of the LED switching power supply housing is the heat dissipation part. When installing, increase the contact area between the housing and the case to facilitate heat dissipation and extend the life of the power supply. If the power supply has a built-in fan, the fan's vent should not be blocked. 6. Before the installation is complete, please carefully check whether the wiring is correct, and prevent incorrect or reverse connections. Re-enable after confirming that it is correct
