Circuits of multi windings transformers

a) primary voltage (V)

b) secondary voltage (V), c) bridge

Example:
If the transformers will be connected to a 460 V rated input voltage the terminals 1.4 and 1.8 must be connected.
If the transformers shall have 230 V rated output voltage, connect the terminals 2.3 and 2.4.
