1. Inductance is measured with both primary windings connected in series (2 to 5, with 3 and 4 shorted).
2. Leakage inductance is measured on winding (2,5) with (3,4) and (7,8,9,10,11) shorted.
3. Maximum operating temperature: Max. operating temp. means the max. ambient plus temp. rise of the transformer.
