施耐德UPS开关电源操作步骤，及常见故障分辨1.按电源键，UPS启动不了:按电源键时间太长短;UPS不接充电电池;电池电压过低;充电电池坏;UPS存有内部结构常见故障
2.电压正常的，UPS并没有电压键入:功率模块后边板上的沟通交流键入过电流保护电源开关在键入过电流的情形下切断电压键入
3.电压红色指示灯或灭掉:市电电压或次数超过规格型号规定
4.报警显示灯长亮，嗡嗡声常鸣，显示灯1～5长亮:负荷负载
5.导出负载，导出关掉，并没有转旁通供电系统:旁通负载关掉导出；旁通工作电压或次数超过工作范畴
6.充电电池备电时间较短:充电电池未充饱
7.电源供电模式中显示灯1～5中只有显示灯1长亮:充电电压过低
8.显示灯4长亮，声控开关每秒钟鸣1声，报警显示灯长亮:风机常见故障
9.显示灯3长亮，嗡嗡声常鸣，报警显示灯长亮:UPS超温
10.显示灯1长亮，嗡嗡声常鸣，报警显示灯长亮:UPS因导出短路故障而关掉导出
11.逆变电源红色指示灯，声控开关常鸣，报警显示灯长亮:逆变电源常见故障
12.显示灯5长亮，嗡嗡声常鸣，报警显示灯长亮:电子整流器常见故障
13.显示灯2长亮，嗡嗡声常鸣，报警显示灯长亮:功率模块的内嵌电池充电器出现故障
14.3kVAUPSIEC导出电源插座无导出:负荷负载，保险丝熔断
PS启动不了:按电源键时间太长短;UPS不接充电电池;电池电压过低;充电电池坏;UPS存有内部结构常见故障
Operation process and fault diagnosis of Weidi UPS power supply:1. Press the power button, UPS will not start: Press the powerbutton for too short a time; UPS not connected to battery; Thebattery voltage is too low; Battery failure; UPS has an internalfault
2. Normal mains power, UPS has no mains power input: The ACinput overcurrent protection switch on the rear panel of the powermodule cuts off the mains power input in case of inputovercurrent
3. The mains indicator light flashes or goes out: the mainsvoltage or frequency exceeds the specification requirements
4. The alarm indicator light is always on, the buzzer soundsconstantly, and the indicator lights 1-5 are always on: loadoverload
5. Output overload, output closed, without switching to bypasspower supply: Bypass overload closes output; Bypass voltage orfrequency exceeds the operating range
6. Short battery backup time: The battery is not fullycharged
7. In battery powered mode, only indicator light 1 remains on inindicator lights 1-5: the battery voltage is too low
8. Indicator light 4 remains on, buzzer sounds once per second,alarm indicator light remains on: fan failure
9. Indicator light 3 is constantly on, buzzer sounds constantly,and alarm indicator light is constantly on: UPS overheats
10. Indicator light 1 is constantly on, buzzer soundsconstantly, and alarm indicator light is constantly on: UPS shutsdown output due to short circuit
11. The inverter indicator light flashes, the buzzer keepsringing, and the alarm indicator light keeps on: the inverter isfaulty
12. Indicator light 5 is constantly on, buzzer soundsconstantly, and alarm indicator light is constantly on: rectifierfault
13. Indicator light 2 is constantly on, buzzer soundsconstantly, and alarm indicator light is constantly on: thebuilt-in battery charger of the power module has malfunctioned
14.3kVAUPSIEC output socket without output: load overload, fuseblown
PS does not start: Press the power button for too short a time;UPS not connected to battery; The battery voltage is too low;Battery failure; UPS has an internal fault
