3 About Rapid Shutdown
3.1 Intended Use of the Rapid Shutdown
The Rapid Shutdown has been especially developed as a safety device for direct current (DC) photovoltaic installations. The DC
disconnect switch is used to discon- nect the connected strings of the installation in case of an emergency situation. Such an
emergency situation could be in case of fire.
3.2 Location of the Rapid Shutdown
The Rapid Shutdown needs to be placed as close to the solar panels as possible. Due to its enclosure, the switch is protected
against external influences like dust and moisture. The whole set-up is conforms to IP66 which makes it suitable for outdoor
usage when needed.
