supported along the mid-section of the panel. These ductwork kits do not support the “in frame” mounting of thepanel (see Rittal TS8 catalogue for details). The duct workcooling kits listed in Table 3.12 are suitable for use onlywith IP00/Chassis frequency converters in Rittal TS8 IP 20and UL and NEMA 1 and IP 54 and UL and NEMA 12enclosures.CAUTIONFor the E2 enclosures it is important to mount the plateat the absolute rear of the Rittal enclosure due to theweight of the frequency converter.CAUTIONA doorfan(s) is required on the enclosure to remove theheat losses not contained in the backchannel of thefrequency converter and any additional losses generatedfrom other components installed inside the enclosure.The total required airflow must be calculated so that theappropriate fans can be selected. Some enclosuremanufacturers offer software for performing thecalculations (i.e. Rittal Therm software). If the frequencyconverter is the only heat generating component in theenclosure, the minimum airflow required at an ambienttemperature of 45 °C for the D3 and D4 frequencyconverters is 391 m3/h (230 cfm). The minimum airflowrequired at an ambient temperature of 45 °C for the E2frequency converter is 782 m3/h (460 cfm).Rittal TS-8EnclosureEnclosure typeD3 Kit PartNo.Enclosure typeD4 Kit Part No.Enclosuretype E2 PartNo.1800 mm 176F1824 176F1823 Not possible2000 mm 176F1826 176F1825 176F18502200 mm 176F0299Table 3.12 Ordering InformationNOTICESee the instruction Duct Work Cooling Kit Instruction forFrames D3, D4 and E2 for further information.External ductsIf additional duct work is added externally to the Rittalcabinet the pressure drop in the ducting must becalculated.

The NEMA-3R enclosure isan outdoor enclosure that provides a degree of protectionagainst rain and ice. The NEMA-4 enclosure is an outdoorenclosure that provides a greater degree of protectionagainst weather and hosed water.The minimum enclosure depth is 500 mm (600 mm forenclosure type E2) and the kit is designed for a 600 mm(800 mm for enclosure type E2) wide enclosure. Otherenclosure widths are possible, however additional Rittalhardware is required.
