3.4 Field Installation of Options
3.4.1 Installation of Duct Cooling Kit in Rittal Enclosures
This section deals with the installation of IP00 / chassis enclosed frequency converters with duct work cooling kits in Rittal enclosures. In addition to the
enclosure a 200 mm base/plinth is required.
Illustration 3.16: Installation of IP00 in Rittal TS8 enclosure.
The minimum enclosure dimension is:
• D3 and D4 frame: Depth 500 mm and width 600 mm.
The maximum depth and width are as required by the installation. When using multiple frequency converters in one enclosure it is recommended that
each drive is mounted on its own back panel and supported along the mid-section of the panel. These duct work kits do not support the “in frame”
mounting of the panel (see Rittal TS8 catalogue for details). The duct work cooling kits listed in the table below are suitable for use only with IP 00 /
Chassis frequency converters in Rittal TS8 IP 20 and UL and NEMA 1 and IP 54 and UL and NEMA 12 enclosures.
NB!
A doorfan(s) is required on the enclosure to remove the heat losses not contained in the backchannel of the drive and any additional
losses generated from other components installed inside the enclosure. The total required air flow must be calculated so that the
appropriate fans can be selected. Some enclosure manufacturers offer software for performing the calculations (i.e. Rittal Therm
software). If the drive is the only heat generating component in the enclosure, the minimum airflow required at an ambient temperature
of 45
o
C for the D3 and D4 drives is 391 m
3
/h (230 cfm).
