6. Installation and Maintenance

Installation

1. Secure the drive in a well-ventilated cabinet free from corrosive gases.
2. Complete the wiring for 3-phase power, output motor, grounding, and control signals in accordance with the wiring diagram.
3. If a display screen or keypad is used, assemble the corresponding panel as instructed in the manual.

Commissioning

1. Set basic parameters (such as motor rated power and acceleration/deceleration time) via the built-in parameter menu or an external PLC/controller.
2. Check the tightness and phase sequence of all wiring connections, then power on the drive only after confirming no abnormalities.

Maintenance

1. Regularly inspect cooling fans and heat sinks for dust accumulation to maintain effective heat dissipation.
2. Check input/output terminals and wiring terminals for looseness or corrosion.
3. Use the drive’s built-in fault diagnosis function or upper-level system monitoring to handle alarm information promptly.
4. Do not allow non-professionals to disassemble internal power modules, as this may pose safety hazards.
