Special Meeting LV Cable Strategy Summary 9/22/21

FERNANDO'S NOTES ON LV POWER DISTRIBUTION

• Link

PRACTICAL IMPLEMENTATION CABLING

• Found suitable connector with 6 pins

• HV
• Ground
• Signal

• Problem: Flat cables interfere with HV cables --> shift connectors

• Horizontal back chaining with shifted connectors

• less work than connector on side, but more risky during assembly/disassembly
• Three issues - most problematic: interference with HV cables

• Discussion: can one cut connector

• need only three pins, so maybe can cut to resolve interference with HV cables

• Alternative: connector on the side

• less risky
• requires more work - have to make additional cables etc.
• requires fabrication of 1000 flat cables and ~30 other cables - time estimate: ~3 weeks
• PCB design time estimate: ~3 months (expect ready early 2022)

• Action item:

• write to DSG and ask if available to take on cable fabrication task
• provide information on connector and placement to Fernando

• Discussion: additional grounding

• action item: investigate how this may be realized

NEXT MEETING: NPS MEETING ON THURSDAY 30 SEPTEMBER AT 9AM ET
