This covers specific, defined abnormal conditions and fault tolerance related to anticipated firefighter operations that exceed the criteria of existing safety standards. Evaluation of equipment and systems for providing a reduced level of shock hazard for conductors exiting the array boundary as well as inadvertent firefighter contact with array equipment and components within the array boundary, sometimes referred to as PV rapid shutdown systems. These requirements cover photovoltaic arrays intended for installation on or integral with buildings. They also cover components intended to provide electrical connection to and mounting facilities for photovoltaic modules. It includes functional safety requirements that address systematic failures and random failures of solid-state electronics.
