Rapid Shutdown (RSD) connection
The installer must use an external rapid shutdown device compliant with
the 2014 NEC.
Automatic shutdown occurs at the rooftop box when utility power is lost
or when the PV system’s AC disconnect switch is opened. In jurisdictions
requiring a dedicated activation switch, install an emergency stop button
external to the inverter.
The wiring box has 24Vdc (0.4A max) on a spring-loaded terminal block
to the left of the PV input area, which is designed to be used to power a
RSD device.
RSD wiring terminals accommodate a wire size range of 26-12 AWG.
- Install RSD device wires in the RSD terminal block;
+24V wire to +RSD terminal,
- 24V wire to - RSD terminal
