Before wiring, please make sure that the input power is in a power off state. 2. Please ask a professional electrical engineer to carry out the wiring work. 3. Please make sure that the grounding terminal is grounded. 4. After the emergency stop circuit is wired, please check if the action is effective. 5. The output line of the inverter must not be connected to the shell, and the output line must not be short circuited. 8. Please connect the braking resistor according to the wiring diagram. 9. Do not connect the power cable to the output U, V and W terminals. 10. Do not connect the contactor to the output circuit. 11. Be sure to install the protective cover before powering up. When removing the cover, be sure to disconnect the power supply. 12. Do not use the inverter with the reset and retry function near mechanical equipment. This is because it will suddenly restart when the alarm stops. 13. Make sure that the alarm is reset only after the operating signal has been cut off. If the alarm is reset in the running signal state, the inverter may start suddenly. 15. Do not change the wiring or dismantle the terminals while the power is on. 16. Cut off the main circuit power before inspection and maintenance. 17. Do not modify the inverter without permission.
