IT IS IMPORTANT TO READ, UNDERSTAND AND FOLLOW THESE
• Series JBEW explosionproof junction boxes are used where hazardous materials are handled or stored. These junction boxes may be used for
terminals, splicing wires, pull boxes or bus boxes.
• Series CSEW explosionproof cast control centers are used where hazardous materials are handled and stored. Cast control centers allow
for auxiliary devices, such as push buttons, switches, pilot devices, etc. to be installed into one enclosure to satisfy a wide range of control
applications. The CSEW Series of enclosures have only been investigated and CLASSIFIED by Underwriters Laboratories as to explosion
and re hazards.
• Refer to the product nameplate for important information regarding the hazardous location rating, enclosure environmental rating, agency
approval(s), and important safety information. Adhere to all warning and caution statements that may be located on the exterior or interior of the
enclosure.
• Class I, Division 1 locations require a conduit seal to be installed in each conduit run within the specied distance noted on the product
nameplate.
• Unused conduit openings shall have a certied close-up plug installed that has the same hazardous location ratings as the enclosure. The
close-up plug must engage a minimum of ve full threads.
• Only qualied personnel should install, inspect, and perform regular maintenance on the enclosure.
• Take extreme care not to damage the at-machined ange when opening the enclosure cover. Damaging the ange could affect the enclosure’s
integrity to protect the hazardous area.
• Dirt, grease, and other foreign material must not accumulate on the at-machined ange surface of the body and cover. The cover and body must
fully mate against each other to provide the proper protection to the hazardous area.
• Do not attempt to repair the cover gasket if damaged; contact factory for replacement. Remove damaged gasket and continue to use the
enclosure. The gasket does not affect on the enclosure’s safety for use in hazardous locations. However, the enclosure’s environmental rating(s)
will no longer be valid.
• Install only approved drain and/or breather ttings that have the same hazardous location ratings as the enclosure. Note, if a drain and/or
breather tting are installed, care must be taken during hosedown operations. The enclosure may be watertight, but the drain and breather may
not be.
• Always keep the cover bolts tight to prevent ignition of hazardous atmospheres and disconnect circuits before opening cover.
• Perform all machining operations prior to installation of the enclosure.
• The enclosure shall be installed in accordance with all national and local electrical codes, and be acceptable to the Authority Having Jurisdiction.
• Since the conditions of use are outside of our control, the purchaser should determine the suitability of the enclosure for the intended use and
assumes all risk and liability in regards to the specic application.

ALL CONDUIT OPENINGS MUST MEET THE FOLLOWING REQUIREMENTS
1. Use TABLE 3 to determine the maximum number of conduit openings permissible to be drilled and
tapped on each side of the enclosure. Openings must be at least 1.5 inches from the inside adjacent
sidewall and 0.75 inches from the inside bottom wall. See FIGURE 3 and 4 for additional information.
2. Consult factory if eld drilling of enclosure back is necessary.
3. For the maximum conduit opening size permissible to be drilled and tapped into the side of the
enclosure, reference TABLE 1. Minimum allowable conduit opening that may be drilled and tapped is
1/2 inch.
4. NPT conduit openings must have at least ve full threads of engagement between the conduit and
enclosure body. ISO-Metric conduit openings must have at least seven full threads of engagement
between the conduit and enclosure body. To determine the minimum wall thickness to engage ve full
NPT threads into the conduit opening without a conduit stop, see TABLE 2.
5. For the minimum center-to-center spacing of any two conduit opening sizes, reference TABLE 3.
Example: Minimum spacing between a 1.0 inch NPT opening (rst column) and 3.0 inch NPT opening
(rst row) is 4.13 inches.
6. Conduit openings shall be a modied National Standard Pipe Taper (NPT) thread, 3/4 inch per foot per
ANSI/ASME B1.20.1 or ISO-Metric thread with a 6H/g tolerance t per the Standard for General Purpose
