Bucking Transformer Wiring Diagram. Connect High Low Voltage L2 to H1. Therefore my thought that a bucking transformer could simply be added to the chassis is way off base.
Typical Three-Phase Buck-Boost Autotransformer Installation Use quantity of Buck-Boost Transformers indicated on chart for connection to be made. Connect using wiring diagram 7 in Buck Boost literature Warning. Im sure this is for safetys sake and is a very wise decision.
Connect H3 and H2 together 6.
An initial appearance at a circuit layout could be complex but if you can read a metro map you could read schematics. To obtain a boost in output over the supply voltage the input voltage is applied across two of the four windings and the output is drawn from terminals that are across all four windings. If you are using this unit as an isolation transformer with a primary of 120 or 240 or 480 volts and the secondary of 1224 1632 or 2448 depending on the model use the wiring diagram located on the inside of the cover to the wiring compartment.
