The SP enclosures are designed for use in nonhazardous locations. The external
SP enclosure is designed to meet either NEMA 12 or NEMA 4X requirements,
depending on the installation:
•
When the external SP enclosure is installed as a stand-alone enclosure, it
meets NEMA 12 requirements because the ventilation openings are exposed
to the environment.
•
When the external SP enclosure is mounted on the side of an AE, it meets
NEMA 4X requirements because the ventilation openings are inside the AE
and are not exposed to the environment.
