5 SMA Rapid Shutdown System Sealing Gaskets for Raintight Conduit
Fittings and Cable Glands
The SMA Rapid Shutdown System consists of one or more Rapid Shutdown Boxes (RSB) and one Rapid Shutdown
Controller (RSC). As shown and specified in the Installation Manual, the RSB and RSC require listed raintight or
liquidtight conduit fittings to attach the conduits to the enclosure. The RSC ships with the appropriate raintight RSC
knockout to
3
⁄
4
NPT adapter. Installers must procure conduit fittings for the RSB and RSC.
SMA recommends using fittings with flat, pliable, thick rubber sealing gaskets per the diagrams below. Thickness should
be of approximately 0.1 inch (approximately
7
⁄
64
inch).
SMA recommends against using fittings with thinner, harder sealing gaskets, typically yellow or green colored. These
types of gaskets may not make reliable seals for this application. Gasket is approximately 0.075 inch (
5
⁄
64
inch) thick or
less.
SMA recommends against and does not accept using fittings with round cross section, o-ring type sealing gaskets as these
types of seals are not reliable for this application.
