Install the AGD-BGD jumper 
Prepare three 22 AWG red wires as shown in Figure 6. One will be used to connect AGD 
to BGD. The other two will be used for voltage select as described in the next section. 
 
Figure 6-Preparing power supply jumper wires 
Connect the AGD and BGD eyelets of the power supply PCB. Insert the jumper from the 
component side and solder on the solder side. 
 
Figure 7-Install AGND to BGND jumper 
Install the voltage select jumpers 
The PR-101 may be wired for either 120 Volt or 240 volt operation. This is done by 
adding jumpers to the power supply board in the marked places.  
 
Jumper locations are shown in Figure 8. 
  For 120 Volts, use the left half of Figure 8. 
  For 240 Volts, use the right half of Figure 8.
