Why is my Huawei UPS5000-E working in bypass mode?
Your Huawei UPS might be working in bypass mode because the UPS working mode is not set to ECO mode. Set the UPS working mode to ECO mode. Alternatively, the bypass transfer times might have reached the upper threshold; clear the bypass transfer times on the LCD.
What to do if the Huawei UPS5000-E bypass is not normal?
If the bypass is not normal, it could be due to a damaged bypass thyristor, in which case you should replace the bypass module. Another reason might be that the bypass module experiences overtemperature. Try to reduce the load, or improve ventilation.
How to fix Huawei UPS5000-E UPS rectifier if it is not normal?
If the rectifier is not normal, it may be because the mains voltage exceeds the upper threshold of 280 V or is less than the lower threshold of 80 V. Check whether the mains voltage exceeds the threshold. If it does, contact the electric power company.
What to do if Huawei UPS5000-E UPS power module is faulty?
If the power module is faulty, replace the power module.
What to do if Huawei UPS5000-E UPS ATS is not normal?
If the ATS is not normal, the input three-phase sequence may be incorrect. Power off the ATS and check the phase sequence.
