junction box, and connect the input 2 port of RSD-D to the other

WARNING: When connecting the RSD-D to only one PV module, use INPUT1 port ONLY, then
connect a DC extension cable to both terminals of INPUT2 to short the unused side, otherwise the
RSD-D may be damaged.

series and then connect to the inverter with a self-made DC
extension cable.
