Ideal For
Not Recommended For
For power transformers, ground the secondary winding at one point. Follow IEC 60076 terminal markings: primary terminals H1/H2, secondary terminals X1/X2. Ensure proper fusing on primary and secondary sides. Never operate with secondary open-circuited if designed for parallel operation; consult manual.
