1. Disconnect external power from the unit.    
   
   
2. Remove the eight black M3 screws on the front panel and keep them somewhere safe. You will need them again.
     
3. Slowly lift the panel from the case, so that you can see the two cables going to the front panel module. 
   
   
4. Disconnect these two cables from the front panel. The module is now free from its enclosure       
   
   
5. Look at the back of your Subharmonicon module. There is a 10-pin power header on the back of the PCB that accepts a 10-pin Eurorack power ribbon cable (not included). 
   
   
6. Connect PIN-1 (-12V) of the power ribbon cable to PIN-1 of the Subharmonicon Eurorack power header. The darkened wire (typically red) on the ribbon cable indicates the PIN-1 (-12V) side of the cable. 
   
   
7. After power is connected, your Subharmonicon may be installed into the rails of the Eurorack system case with the eight black M3 screws removed in Step 2.
8. Once fully installed, you may power up your Eurorack system.
