I purchased a power transformer with dual primary windings. Reading up on the correct way to hook up the primary coils in parallel for 115V, the proper way is to connect the coils by tying the positive with the positive and the negative to the negative. This is indicated by the dot on the diagram as well.
However, on the datasheet for the power transformer I bought, the diagram looks different. Each of the terminals is labeled with a voltage.
How do these two diagrams map to each other?
Is the correct connection for parallel to connect 115V to 115V and 0V to 0V, (1 -> 4 and 2 -> 3), or is it connecting the 0V terminals to the opposite 115V terminals (1 -> 3 and 2 -> 4)?
Here is the product listing in question.
