A: 1. There are two triggering methods for UPS EPO, one is EPO button (local EPO) and the other is dry contact (remote EPO). You can first connect the UPS to the MTR software, enter the "Service Settings" to disable remote EPO, and observe if the device still experiences this phenomenon. If the device no longer experiences EPO triggering abnormalities, the dry contact board of the device needs to be replaced.
2. If the problem persists, it may be due to an abnormality in the circuit of the EPO button. Then disable the local EPO and observe the device's operation. This situation may be due to damage to the control board or monitoring board of the device.
