Pengaturan dan Instalasi

1. Pemasangan

• Mount the VFD vertically on a DIN rail within an electrical enclosure. Ensure adequate ventilation space around the unit (at least 10cm clearance on all sides) for heat dissipation.
• Avoid mounting in direct sunlight, high humidity, or dusty environments.

2. Koneksi Kabel

Refer to the terminal labels on the VFD and the wiring diagram provided in the full product documentation (not included here) for precise connections. Ensure all connections are secure and correctly polarized.

• Power Input (L, N): Connect the single-phase 220VAC power supply to the 'L' and 'N' terminals.
• Output Motor (U, V, W): Connect the three-phase motor leads to the 'U', 'V', and 'W' terminals.
• Dasar (PE): Connect the protective earth ground to the 'PE' terminal. This is crucial for safety.
• Terminal Kontrol: Utilize the digital inputs (DI), analog inputs (AI), and relay outputs (TA, TB, TC) for external control signals, speed potentiometers, and status indications as required by your application.

Always double-check all wiring before applying power.

Petunjuk Pengoperasian
