What to do if Huawei PowerCube 500 UPS shows AC Overvoltage?
If the Huawei UPS reports an AC overvoltage, first verify if the AC input voltage is abnormal. If it is, identify and fix the problem to protect the function module from high voltage damage. If the AC input voltage is normal, the AC detection circuit of the module may be faulty and you should contact Huawei technical support.
Why is my Huawei UPS showing AC Undervoltage?
If your Huawei UPS is showing an AC undervoltage error, start by checking if the AC input voltage is too low and if it is abnormal. If the grid has a fault, rectify it. If the voltage seems fine, check all cable connections to ensure they are properly connected. If the cables are loose, reconnect them. If the cables are correctly connected, contact Huawei technical support.
