Careful installation is crucial for the performance and safety of the VFD. Ensure all safety precautions are followed.

5.1 Unpacking ati ayewo

  • Unpack the VFD and inspect it for any physical damage during transit.
  • Verify that all components listed in the package contents are present.

5.2 Iṣagbesori

  • Mount the VFD vertically on a stable, non-flammable surface.
  • Ensure adequate ventilation space around the unit (minimum 10 cm on all sides) to prevent overheating.
  • Avoid mounting in direct sunlight, high humidity, or dusty environments.

5.3 Onirin

Refer to the detailed wiring diagrams provided in the included user manual for specific connection points. The following are general guidelines:

  • Iṣagbewọle agbara: Connect the single-phase 220V AC power supply to the designated input terminals (typically L1, L2).
  • Iṣajade mọto: Connect the three-phase 380V motor to the output terminals (typically U, V, W). Ensure the motor is rated for 380V and has a power rating less than or equal to 7.5KW.
  • Ilẹ: Connect the ground terminal of the VFD to a reliable earth ground.
  • Asopọmọra Iṣakoso: If external control (e.g., potentiometer, external switches) is used, connect according to the manual's control terminal diagrams.
