Conduit Connections
Conduits connected to an outdoor enclosure can introduce water vapor into the enclosure and lead
to the formation of condensation inside. Failure to follow these guidelines can result in water
intrusion into the unit through the conduit connections and may void the warranty.
Follow these instructions and best practices when securing conduits to the DC De-Combiner and the AC
Combiner.
1. Use UL514B certified water-tight conduit fittings and proper installation methods to provide a
water-tight connection that will maintain the rating of the enclosure.
2. Use an appropriately rated sealant and seal the conduits fully to prevent the exchange of air
between the conduit and the enclosure. Sealing the conduit will help prevent condensation in
the enclosure.
