1. If the overvoltage/undervoltage issue occurs occasionally, it might be due to a short-term abnormality in the power grid. In such cases, the equipment will resume normal operation automatically once the power grid stabilizes, and no manual intervention is needed.
2. If it occurs frequently, it is essential to check whether the grid voltage is within the allowed range. If it is obviously high or low, it is advisable to contact the local power utility. With their consent, you can adjust the grid overvoltage or undervoltage limits through the monitoring platform to address the problem.
