3.4.5 Outside Installation/NEMA 3R Kit forRittal Enclosures176FT261.10Figure 3.41 Rittal Enclosure Size E2This section is for the installation of NEMA 3R kits availablefor the adjustable frequency drive enclosure size E2. Thesekits are designed and tested to be used with IP00/Chassisversions of these enclosure sizes in Rittal TS8 NEMA 3R orNEMA 4 enclosures. The NEMA 3R enclosure is an outdoorenclosure that provides a degree of protection against rainand ice. The NEMA 4 enclosure is an outdoor enclosurethat provides a greater degree of protection againstweather and hosed water.The minimum enclosure depth is 500 mm (19.7 in) (600mm (23.6 in) for enclosure size E2) and the kit is designedfor a 600 mm (23.6 in) (800 mm (31.5 in) for enclosure sizeE2) wide enclosure. Other enclosure widths are possible;however, extra Rittal hardware is required. The maximumdepth and width are as required for the installation.NOTICE!Adjustable frequency drives in enclosure type E2 requireno derating.NOTICE!Install a door fan on the enclosure to remove the heatlosses not contained in the backchannel of theadjustable frequency drive and any additional lossesgenerated from other components installed inside theenclosure. Calculate the total required airflow to selectthe appropriate fans. Some enclosure manufacturersoffer software for performing the calculations (RittalTherm software). If the adjustable frequency drive is theonly heat-generating component in the enclosure, theminimum airflow required at an ambient temperature of45 °C (113 °F) for the E2 adjustable frequency drive is782 m3/h (460 cfm).Ordering information• Enclosure size E2: 176F18843.4.6 Outside Installation/NEMA 3R Kit forIndustrial EnclosuresThe kits are available for the enclosure size E2.
