5. 유지관리
- 배터리 관리 : The UPS uses Lead Acid batteries. To prolong battery life, avoid frequent deep discharges and operate the UPS within recommended temperature ranges. Periodically perform a battery self-test if available through the monitoring software.
- 청소: Keep the UPS clean and free from dust. Use a soft, dry cloth to wipe the exterior. Do not use liquid or aerosol cleaners. Ensure ventilation openings are not blocked.
- 저장: If storing the UPS for an extended period, ensure it is fully charged and then recharge it every 3 months to prevent battery degradation.
6. 문제 해결
This section addresses common issues you might encounter with your UPS. For more complex problems, contact customer support.
- UPS가 켜지지 않음: Check if the AC input cable is securely connected and if the input circuit breaker has tripped. Ensure the battery is sufficiently charged.
- 짧은 배터리 사용 시간: This may indicate aging batteries or an overloaded UPS. Reduce the connected load or consider battery replacement if the unit is old.
- 큰 팬 소음: Some users have reported noticeable fan noise. While often normal for cooling, ensure the ventilation is not obstructed. If the noise is excessive or unusual, contact support.
- 연결된 기기에 전원이 공급되지 않습니다: Verify that the UPS is on and not in a fault state. Check the output receptacles and ensure devices are properly plugged in.
