Why is my Inovance H0U-88B1G reporting an over current fault for the fan?
An over current fault reported for the fan can be due to an inaccurate transformation ratio setting of CT2 or an inaccurate fan rated current setting. To resolve this, ensure that 'Protection current' is greater than 'rated current'.
