Figure 8 50-SPS600-1B Line Voltage Jumpers 

 
For 220/240VAC operation (default setting), place the jumper on the 220VAC terminal.  
For 110/120VAC operation, place the jumper on the 110VAC terminal. Do not change 
any other jumpers on the board. Do this for both power supply modules in the power 
supply.
