Usage Instructions

Grounding Protection

Ensure that the equipment is properly grounded in accordance with national and local electrical safety standards.

Installation Environment

Choose a dry, well-ventilated location away from heat sources and strong electromagnetic interference. Ensure the installation surface is flat and sturdy, with sufficient load-bearing capacity.

Inspection of Accessories

Check that all accompanying cables, terminal blocks, and other accessories are complete.

Wiring Operations

Strictly follow the electrical wiring diagram in the product manual. Distinguish between different wiring ports such as power input, motor output, and control signals. Ensure that all connections are secure and free from looseness. After completing the wiring, carefully inspect to prevent short circuits, open circuits, and other errors. Pay special attention to grounding protection to ensure the safety of the equipment and personnel.

Parameter Settings

Before powering on, familiarize yourself with the functions of the inverter's operation panel. After powering on, enter the parameter setting interface and set basic parameters such as rated voltage, current, frequency, and control mode according to the motor's nameplate parameters and application requirements. Also, set operational parameters such as acceleration time, deceleration time, and torque compensation. Save the settings and perform a trial run, adjusting parameters as necessary based on actual operating effects.

Maintenance and Inspection

Daily Cleaning

Regularly clean the surface of the inverter to remove dust and debris. This prevents dust accumulation from affecting heat dissipation and prevents debris from entering ventilation ports and terminal blocks, which could cause faults. It is recommended to perform a simple cleaning once a month.

Heat Dissipation Check

Monitor the operation of the cooling fans, checking for any damage or deformation of the blades, and ensuring smooth and quiet operation. Regularly clean the fan filters to ensure unobstructed airflow. If a fan fault is detected, replace it promptly.

Electrical Performance Testing

Conduct electrical performance tests every quarter or half-year. Use professional instruments to measure input and output voltage and current, check grounding resistance, and inspect the connections of all terminal blocks. Address any abnormalities promptly.

Precautions

• Avoid Overloading: Ensure that the motor and load are selected according to the inverter's rated capacity. Do not exceed its rated load capacity. Long-term overloading will accelerate equipment aging and damage, and may even cause safety accidents.

• Cope with Grid Fluctuations: If the local grid quality is poor with frequent voltage fluctuations, consider adding a voltage stabilizer or filter to ensure the stability of the input power to the inverter, preventing equipment damage due to grid anomalies.

• Operational Safety Protection: When debugging or maintaining the inverter, ensure the power is disconnected and the capacitors are fully discharged before proceeding. Operators should wear insulating gloves and use insulated tools to prevent electric shock. Non-professionals are strictly prohibited from disassembling or repairing the equipment.
