DC-DC CONVERTER AND FRONT JUNCTION BOX
High voltage is present at the DC-DC converter and front junction box, as outlined in red. The DC-DC converter transforms the high
voltage current from the high voltage battery to low voltage to charge the Model S 12 volt battery. The front junction box provides high
voltage current to various components, such as the battery heater, air conditioning compressor, and cabin heater. Use caution when
cutting in this area during a dash lift and dash roll procedure. Use work-around techniques, if necessary.
NOTE: The following image shows a Dual Motor vehicle. Vehicles without a front drive unit are similar.
