4. When the breaker is grounded on the secondary side of the inverter, it may be
unnecessarily operated by harmonics if the effective value is less than the
rating. In this case, note that the eddy current and hysteresis loss increase
and temperature rises.
5. For the leakage current value of the noise filter installed on the inverter input
side, contact the corresponding filter manufacturer.
