an external short.
• The fuses can be reset by shutting off power and waiting a few
minutes (the fuses automatically reset when cooled) then
reapplying power.
Cable specification • 9 contact type D male EMI connector
• Backshell–EMI metallized plastic

wire(s) connected to the metallized backshell at the chassis.
