6. Installation and Maintenance Recommendations
- Electrical Connection: Ensure the power supply voltage complies with 460V AC, and correctly connect the power cables and control cables.
- Heat Dissipation: During installation, maintain sufficient heat dissipation space around the inverter, avoid stacking flammable items, and ensure the cooling fan works normally.
- Grounding: Correct grounding is crucial to ensure the normal operation of the inverter and prevent electromagnetic interference.
- Parameter Setting: Configure the corresponding parameters (such as motor rated current, acceleration/deceleration time, torque setting, etc.) in the control panel or upper computer software according to the specific motor and load requirements.
- Regular Inspection: Regularly check the tightness of input and output terminals, cooling fans, and internal connecting wires.
