enclosure 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. The maximum depth and width areas required by the installation.NOTICEThe current rating of frequency converters in enclosuretypes D3 and D4 are de-rated by 3%, when adding theNEMA 3R kit. Frequency converters in enclosure type E2require no derating.NOTICEA 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).Ordering informationEnclosure type D3: 176F4600Enclosure type D4: 176F4601Enclosure type E2: 176F1852NOTICESee the instructions Installation of NEMA 3R Kit for IP00Frames D3, D4 & E2 for further information.3.3.6 Outside Installation/NEMA 3R Kit ofIndustrial EnclosuresThe kits are available for the frame sizes D3, D4 and E2.These kits are designed and tested to be used with IP00/Chassis frequency converters in welded box constructionenclosures with an environmental rating of NEMA-3R orNEMA-4. The NEMA-3R enclosure is a dust tight, rain tight,ice resistant, outdoor enclosure. The NEMA-4 enclosure is adust tight and water tight enclosure.This kit has been tested and complies with UL environ-mental rating Type-3R.Note: The current rating of D3 and D4 frame frequencyconverters are de-rated by 3% when installed in a NEMA-3R enclosure. E2 frame frequency converters require no de-rating when installed in a NEMA-3R enclosure.NOTICESee the instruction for Outside Installation/NEMA 3R kit ofindustrial enclosures, 175R1068, for further information.Ordering informationFrame size D3: 176F0296Frame size D4: 176F0295Frame size E2: 176F02983.3.7 Installation of IP00 to IP20 KitsThe kits can be installed on frame sizes D3, D4, and E2(IP00).CAUTIONSee the instruction for Installation of IP20 Kits,175R1108, for further information.Ordering informationFrame size D3/D4: 176F1779Frame size E2: 176FXXXX3.3.8 Installation of IP00s D3, D4, & E2Cable Clamp BracketThe motor cable clamp brackets can be installed on framesizes D3 and D4 (IP00).NOTICESee the instruction forCable Clamp Bracket Kit, 175R1109,for further information.Ordering informationFrame size D3: 176F1774Frame size D4: 176F1746Frame size E2: 176F17453.3.9 Installation on PedestalThis section describes the installation of a pedestal unitavailable for the frequency converters enclosure types D1and D2. This is a 200 mm high pedestal that allows theseenclosure types to be floor mounted. The front of thepedestal has openings for input air to the powercomponents.The frequency converter gland plate must be installed toprovide adequate cooling air to the control components ofHow to Install VLT® Automation Drive FC 300 Operating InstructionsMG33U402 - Rev. 2013-12-16 393 3
