5.2 배선 연결
중요한: All wiring must comply with local electrical codes and regulations. Ensure power is OFF before making any connections.
- Identify the input (IN) and output (OUT) terminals on the meter.
- Connect the incoming three-phase lines (L1, L2, L3) and Neutral (N) to the corresponding IN terminals (typically 5, 6, 7, 8).
- Connect the outgoing three-phase lines (L1, L2, L3) and Neutral (N) to the corresponding OUT terminals (typically 1, 2, 3, 4).
- 모든 연결 부분이 단단하고 안전하게 되어 있는지 확인하여 접촉 불량과 과열을 방지하세요.
