5. सेटअप

Careful installation and wiring are crucial for the proper functioning of the VFD inverter.

5.1 माउंटिंग

• Mount the inverter vertically on a stable, non-flammable surface.
• Ensure adequate clearance around the unit for proper ventilation and heat dissipation.
• Avoid mounting in areas with excessive vibration, dust, or moisture.

5.2 वायरिंग

Refer to the wiring diagram provided with your specific unit for detailed connections. General wiring steps include:

1. पॉवर इनपुट (L, N): Connect the main AC power supply to the L and N terminals. Ensure correct voltage (220V AC).
2. मोटर आउटपुट (U, V, W): Connect the three-phase motor leads to the U, V, and W terminals.
3. Grounding (PE): Connect the ground wire to the PE terminal for safety.
4. Brake Resistor (P+, PB): If a brake resistor is used, connect it to the P+ and PB terminals.
5. नियंत्रण टर्मिनल्स: Connect external control signals (digital inputs, analog inputs, relay outputs) to the respective terminals as per your application requirements.
