Outside Installation/Nema 3R Kit For Rittal Enclosures - Danfoss VLT AQUA Drive FC 202 Design Manual

Selection
The maximum depth and width must comply with the
installation requirements. When using multiple frequency
converters in one enclosure, mount each on its own back
panel and support each along the mid-section of the
panel. The back channel cooling kits do not support the
"in frame" mounting of the panel (see Rittal TS8 catalogue
for details). The cooling kits listed in Table 3.14 are suitable
for use only with IP00/IP20 chassis frequency converters in

This section is for the installation of NEMA 3R kits available
for the frequency converter frames D3h, D4h and E2. These
kits are designed and tested to be used with IP00/IP20/
Chassis versions of these frames in Rittal TS8 NEMA 3R or
NEMA 4 enclosures. The NEMA-3R enclosure is an outdoor
enclosure that provides a degree of protection against rain
and ice. The NEMA-4 enclosure is an outdoor enclosure
that provides a greater degree of protection against
weather and hosed water.
The minimum enclosure depth is 500 mm (600 mm for E2
frame) and the kit is designed for a 600 mm (800 mm for
E2 frame) wide enclosure. Other enclosure widths are
possible, however more Rittal hardware is required. Consult
the installation requirements for the maximum depth and
width.
NOTICE
The current rating of frequency converters in D3h and
D4h frames are de-rated by 3%, when adding the NEMA
3R kit. Frequency converters in E2 frames require no
derating.
