5. 설치
중요한 안전 고지: Installation should only be performed by a qualified electrician. Ensure the main power supply is disconnected before commencing any wiring work. Failure to do so may result in electric shock or damage to the device.
- 설치: The device is designed for DIN rail mounting. Securely attach it to the DIN rail within your electrical panel.
- 배선: 아래 배선도를 참조하십시오.
- Connect the incoming Live (L) and Neutral (N) wires to the "IN" terminals at the top of the protector.
- Connect the outgoing Live (L) and Neutral (N) wires from the "OUT" terminals at the bottom of the protector to your load or downstream circuit breaker.
- 모든 연결 부분이 단단하고 안전하게 되어 있는지 확인하여 접촉 불량과 과열을 방지하세요.
- 확인: 배선 작업 후에는 전원을 복구하기 전에 모든 연결 부분이 정확하고 안전한지 다시 한번 확인하세요.

6. 운영
Once installed and powered on, the device will display the current voltage on its LCD screen. You can adjust the overvoltage와 언더볼tage protection thresholds using the control buttons.
- Viewing Current Voltage: The LCD continuously displays the real-time circuit voltage.
- 설정 모드로 진입: 를 누르고 계세요 세트 button for approximately 3-5 seconds until the display starts flashing.
- Adjusting Overvoltage Threshold (U>):
- While in setting mode, press the 세트 button repeatedly to cycle through parameters until "U>" (Overvoltage) is displayed and flashing.
- 사용하세요 위로(▲) 그리고 아래로(▼) buttons to adjust the desired overvoltage protection value (221V-290V).
- Adjusting Undervoltage Threshold (U<):
- 를 누르세요 세트 button again to cycle to "U<" (Undervoltag이자형).
- 사용하세요 위로(▲) 그리고 아래로(▼) buttons to adjust the desired undervoltage protection value (150V-219V).
- 설정 저장: After adjusting all desired parameters, wait for approximately 5-10 seconds without pressing any buttons. The device will automatically save the settings and exit the setting mode.
- 수동 재설정: 볼륨의 경우tage fault, the device will trip. Once the voltage returns to normal, it will automatically reconnect. If manual intervention is required, power cycle the device.
7. 유지관리
The SINOTIMER SVP-915-40A is designed for minimal maintenance. Follow these guidelines to ensure optimal performance and longevity:
- 정기 검사: Periodically inspect the device and its wiring for any signs of damage, loose connections, or discoloration.
- 청소: 기기를 깨끗하게 유지하고 먼지와 이물질이 쌓이지 않도록 하십시오. 마른 부드러운 천으로 닦으십시오. 액체 세척제는 사용하지 마십시오.
