When the inverter loses utility power, the DC output conductors between the RSD
Combiner and the inverter become de-energized below 30V within 10 seconds. The
utility power can be cut off at any point upstream of the inverter to allow the
contactors to open inside the RSD Combiner, ensuring there is no high voltage DC
between the inverter and the RSD Combiner.
The PV system with rapid shutdown ability shall be properly labeled according to NEC
690.56 (C). The sign/label should be right at the service entrance and match the sample
below (text and color scheme).
