Changing voltage

The transformer has a pcb board with a fuse for the main input.  If you want to change the voltage , you must first remove the pcb board.

The main lead is connected to the 0V and 115V as show in the photo.

115 Volt:  Remove the wire between the mid  0V -115V. Connect the not connected 0V to the other 0V and the not connected 115v to  the other 115V.

230 Volt:  ​connect the mid 0V to the mid 115v. See Photo
