Subject: CyMAC Power connections made 
Finished power connections today for the CyMAC chassis. Images attached. Had to switch the shrink fork terminals on the power supply cables to shrink ring terminals, but was able to get everything connected and secured. Upcoming work: turning on power supply and testing voltages/checking everything is turning on and lighting up correctly. Configuration is as follows:
  • Topmost Sorensen: +24V (reserved for FROSTI)
    • Positive terminal:
      • unconnected for now
    • Negative terminal: [negative terminal is grounded]
      • jumper to Sorensen ground screw
  • Sorensen 2nd from the top: +18V
    • Positive terminal:
      • white power cable wire for AA chassis
      • white power cable wire for AI chassis
      • white power cable wire for BI chassis
      • white power cable wire for BO chassis
    • Negative terminal: [negative terminal is grounded]
      • jumper to Sorensen ground screw
      • black power cable wire for AA chassis
      • black power cable wire for AI chassis
      • black power cable wire for BI chassis
      • black power cable wire for BO chassis
  • Sorensen 3rd from the top: -18V
    • Positive terminal:[positive terminal is grounded]
      • jumper to Sorensen ground screw
      • green power cable wire for BI chassis
      • green power cable wire for BO chassis
    • Negative terminal:
      • green power cable wire for AA chassis
      • green power cable wire for AI chassis
  • Bottommost Sorensen: +6V
    • Positive terminal:
      • white power cabe wire for timing chassis
    • Negative terminal: [negative terminal is grounded]
      • jumper to Sorensen ground screw
      • green power cable wire for timing chassis
      • black power cable wire for timing chassis
