Fuse Diagnostics
Interface Box Fuse
This fuse provides protection for the interface box’s internal power supplies for the video receivers and
communications circuitry. If triggered, this fuse will disable video receivers and vehicle communications.
Vehicle Power Fuse
This fuse is located in line with the 350VDC output to the tether. If triggered, this fuse will disable the
400VDC output but not the power supplies themselves.
This is a high voltage fuse and must only be
replaced with an identically rated fuse type.
Input Fuse (Power Supply Rack)
This fuse protects the high voltage power supply and all auxiliary power supplies within the power supply
rack. If tripped, this breaker will cut power to the supplies and, as a result, all power delivery to the
vehicle. A tripped main power breaker is a sign of a significant and sustained short-circuit either at the
power supplies or within the interface box. This equipment should be carefully evaluated before
attempting to re-power.
Tether Re-termination
Tether termination is a specialized service beyond the scope of this manual. Contact Eddyfi
Technologies if the tether is damaged or requires re-termination.
