Separate enclosures can be used with open style devices for field assembly of enclosed controls. These enclosures, plus the open style components, are equivalent to a factory-assembled device. Separate enclosures are for use only with the following equipment:

• NEMA 4 and 12 Class 9991 separate enclosures for Type S devices come standard with closing plates. See Selection, Class 9991 for the specific number of closing plates. For applications requiring enclosures without closing plates, contact your nearest Schneider Electric sales office.

• NEMA 3R enclosures for field assembly of equipment for outdoor applications come with three closing plates, a reset mechanism, and a predrilled panel as standard. For a conduit connection to the top of these enclosures, select watertight hubs from the listing on Digest page 3-10 in accordance with applicable code requirements. Square D NEMA 12 enclosures can also be modified for outdoor use. For details, refer to the NEMA 12 enclosure modification information on page Selection. NOTE: Not for use in high-corrosive outdoor locations or sea coast environments.

• NEMA 4X enclosures for Type S devices, Sizes 0–2 and 30–60 A, come standard without closing plates. Cover mounted control units for NEMA 4X separate enclosures are available as a factory modification only.

When closing plates are removed from NEMA 4, 12, and 3R enclosure covers, the openings can be used for easy installation of Class 9001 Type K or SK cover-mounted control units. Convenient Class 9999 modification kits containing Class 9001 Type K control kits can be found on page Cover-Mounted Control Units.
