설치 및 작동 참고 사항
- Bolt‑on mounting; strictly follow specified bolt torque values for each model to avoid bad contact & over‑heating.
- 권장 연속 작동 전류는 퓨즈 정격 전류의 ≤75%입니다. 주변 온도가 40℃를 초과하는 경우 온도 저하 계수를 적용하십시오.
- For closed‑box / high‑altitude installation (>2000m), implement rated‑current derating according to technical manual.
- 병렬 설치는 더 높은 전류 용량을 위한 치수 및 사양 지침을 준수하는 경우에만 허용됩니다.
- 인증된 부하 차단 스위치 장치가 장착되어 있지 않은 경우, 활선 DC 부하 상태에서 퓨즈를 교체하지 마십시오.
- Replace fuse immediately if mechanical damage, crack or deformation occurs.
- Extra reliability validation test is required for extremely high‑vibration vehicle operating environments.
