Warning
This Photovoltaic Rapid Shutdown Equipment (PVRSS) does not perform all of the functions of a complete Photovoltaic Rapid Shutdown Equipment (PVRSS). This PVRSS must be installed with other equipment to form a complete PVRSS that meets the requirements of NEC (NFPA 70) section 690.12 for controlled conductors outside the array. Other equipment installed in or on this PV system may adversely affect the operation of the PVRSS. It is the responsibility of the installer to ensure that the completed PV system meets the Rapid Shutdown functional requirements. This equipment must be installed according to the manufacturer’s installation instructions.
