In a recent blog post, Industrial Enclosure Selection: Getting Familiar with Standards and Ratings, we discussed the main differences between industrial and standard IT enclosures (industrial enclosures are completely sealed when closed). We also discussed the importance of having a basic understanding of the standards that define the degrees of environmental protection by enclosure in order to help to simplify selection.
With the above in mind, when you extend your network into nontraditional spaces, you can satisfy most nonhazardous location requirements by focusing on three enclosure ratings: IP54 / NEMA Type 12, IP66 / NEMA Type 4 and NEMA Type 4X. The table below provides a comparison and typical applications.
The three enclosures listed in the table cover the majority of nonhazardous environment requirements and can be field-adapted with drains, vents, fans or air conditioners as required. An additional table below provides a list of other ratings covered by the three types listed. Note that there are different enclosures (ratings) used in hazardous locations around flammable dust and chemicals, such as mines, refineries, mills and aboard ship.
Once you have determined the enclosure rating you need, then you can work towards selecting the enclosure style and size that best fits your application. There are four basic styles of industrial enclosures:
Modular enclosures are most similar to IT equipment cabinets.
Free-Standing EnclosuresFree-standing enclosuresare simpler designs, formed as single monolithic enclosures in specific sizes used as stand-alone enclosures.
Floor-mount enclosures are similar to free-standing enclosures formed as single monolithic enclosures in specific sizes used as standalone enclosures.
Wall-mount enclosures attach to the wall and support smaller amounts of equipment.
Enclosures are typically selected to match equipment mounting requirements according to useable space and size. If the enclosure has 19" EIA mounting rails, then the usable space is according to the rack-mount space and depth of the enclosure. If the enclosure has a panel, then the usable space is based on the panel size and depth of the enclosure. The overall size of the enclosure should provide sufficient clearance to ensure the equipment and connections will fit in the location and provide sufficient air circulation.
Select cooling and cable accessories to match your equipment and cabling requirements. Remote monitoring for power, environmental and access control should be considered to provide real-time monitoring and alerts if an issue is detected. Unlike IT cabinets, mounting rails and panels are typically ordered separately; however, CPI provides kitting and configuration services to simplify ordering and ensure compatibility.
