Transformer
The step down transformer uses two lines of AC voltage totaling 200-
240Vac, and steps down that voltage to many separate lines of reduced
AC voltage.
The machine will not operate correctly unless the jumper plug (located
on the DC power supply board) and transformer connectors are set to
line voltage.
