Specification: Item Type: Variable Frequency Drive Material: ABS Storage Temperature: -25℃~+55℃ Input Voltage: 3 phase 380-440V AC. Output Voltage: 3 phase 0-440V AC. Package List: 1 x Variable Frequency Drive 1 x User Manual Note: 1. Before wiring, please confirm whether the input power is in power off state. 2. For wiring work, please Ask professional electrical engineers to do it.. 3. The grounding terminal must be grounded. 4. After the emergency stop circuit wiring is completed, be sure to check whether the action is valid. 5. Do not connect the output wire of the inverter with the shell, and do not short circuit the output wire. 6. Please confirm whether the voltage of the AC main circuit power supply is consistent with the rated voltage of the inverter. 7. Do not perform withstand voltage test on the inverter. 8. Please connect the braking resistor according to the wiring diagram. 9. Do not connect the power cord to the output U, V, W terminals. 10. Do not connect the contactor to the output circuit. 11. Be sure to install the cover before powering on. When removing the cover, be sure to disconnect the power. 12. The inverter that selects the reset and retry function should not be close to the mechanical equipment, since it will restart suddenly when the alarm stops. 13. After confirming that the running signal is cut off, the alarm can be reset. If the alarm is reset in the state of running signal, the inverter may start suddenly. 14. Do not touch the terminals of the inverter since there is high voltage on the terminals, which is very dangerous. 15. During power on, do not change wiring and disassemble terminal.
