3.4. Field Installation of Options
This chapter deals with the installation of IP00 / chassis enclosed frequency converters with duct
work cooling kits in Rittal enclosures. These kits are designed and tested to be used with Rittal
TS8 enclosures 1800 mm (Frame D1 and D2 only) and 2000 mm height as well as 2200 mm for
E2 enclosures. Other enclosure heights are not supported. In addition to the enclosure a 200 mm
base/plinth is required.
The minimum enclosure dimension is:
•
D1 and D2 frame: Depth 500 mm and width 600 mm.
•
E1 frame: Depth 600 mm and width 800 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.
The duct work shown is for D1 and D2 enclosures. The duct work for E1 enclosures has a different
look, but is installed in the same way.
For the E1 enclosures it is important to mount the plate at the absolute rear of the
Rittal enclosure due to the weight of the frequency converter.
