१० तारि Conn जडानहरू

महत्त्वपूर्ण: All wiring must comply with local electrical codes and regulations. Ensure power is OFF before making any connections.

1. Identify the input (IN) and output (OUT) terminals on the meter.
2. Connect the incoming three-phase lines (L1, L2, L3) and Neutral (N) to the corresponding IN terminals (typically 5, 6, 7, 8).
3. Connect the outgoing three-phase lines (L1, L2, L3) and Neutral (N) to the corresponding OUT terminals (typically 1, 2, 3, 4).
4. सम्पर्कहरू खुकुलो हुन र अत्यधिक तातो हुनबाट जोगाउन सबै जडानहरू कडा र सुरक्षित छन् भनी सुनिश्चित गर्नुहोस्।
