2.4 IMPORTANT: Drainage Holes
When the enclosure is installed, drill two 1/4” (6mm) holes at the lowest point in the
enclosure, to allow any water inside the enclosure to drain away. If the enclosure is
mounted vertically, drill two holes in the bottom of the lower fiberglass cowl.
The NEMA 3R standard to which the enclosure is designed allows some water ingress,
provided there is a drainage path for the water to escape. Small amounts of water will not
cause any damage, provided they can drain away.
