Got the same problem with upper DC volts than it shows on the schematic so I look at jumpers and it was on 200 volts but got 230volts at my power receptacle...so I put the 240 volts jumper and the Vdc downs at the right power like on the schematic...you might take volts at your power receptacle and if you got 110VAC you might put the jumper for upper voltage and put the 120VAC jumper.
Jumpers are in a sealed bag fixe to the cabinet on the right of the transformator.
Sorry for my bad English and hope that could help you
