Precautions for operating variable frequency power supply:
　　Today,I will share with you the operating precautions for Zhonggang Yangsheng three-phase variable frequency power supply,60HZ variable frequency power supply,and high-power variable frequency power supply:
　　After confirming that the input voltage is correct,connect the input wire properly.
　　2.Turn on the input switch and wait for 30 to 60 seconds before starting the machine.
　　When debugging voltage and frequency,please turn off the output switch.After adjusting the required voltage and frequency for the load,turn on the output switch and start the load.
　　4.Do not switch frequency and voltage during use with load.If you need to switch,please turn off the load and voltage output switches first.
　　5.When shutting down,please shut down in the following order:turn off the load-turn off the machine output-press the power reset button-turn off the input switch-and finally cut off the power.
