2 SMA Rapid Shutdown Controller Wiring/Cabling
The SMA Rapid Shutdown System consists of a Rapid Shutdown Box (RSB) and a Rapid Shutdown Controller (RSC).
As shown and specified in the Installation Manual, RSBs and RSCs are connected with control wires, and multiple RSBs
can be controlled with a single RSC. Below are the specifications and examples of recommended wire types and sources.
Requirements for Control Wires
18 AWG to 16 AWG copper conductors
Solid wire, stranded wire or finely stranded wire. When using finely stranded wire, bootlace ferrules must be used.
Examples
Tray cables for exposed run (TC-ER)
Where 600V rated cable is required:
Belden 28335A Multi-Conductor – 600V Type TC-ER Cable or similar
In conduit with PV output conductors (600V rated)
TFFN individual copper conductors sizes AWG 18–16, 600 V
or
