overheating of the alternator and/or DC cabling.
2. Check for loose/high resistance connections and ensure that appropriate gauge wiring is used in the
installation.
3. Do not install the Smart BMS unit in a location exposed to high temperature or radiant heat. Relocate the
Smart BMS to a cooler position or provide additional active cooling.
