It is a dual primary transformer. I labeled the pins 1-4 . Pins 1&3 are one primary winding and pins 2 & 4 are the other.
First confirm that there is a DC resistance between 1&3 and 2&4 and that there is no connection between the even and odd numbered pins.
For 115V operation connect 1&2 and connect 3&4
For 230V operation apply voltage to 1&4 and jumper 2&3
