    Tips: Additional notes about installation of isolation transformer:

    1. The secondary ends of the transformer to be grounded is forbidden;
    2. People is prohibited to touch the transformer's terminals at the same time, otherwise, electric shock could occur.
    3. Users usually ignore the importance of the grounding of isolation transformer. It reduces the effect of transformer because of the bad isolation measures.
    4. Isolation transformer has the function of harmonic filtration, however, if the requirement beyond the supply, it is best to add a filter.
