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 Table 3.12 are suitable for use only
with IP00/Chassis frequency converters in Rittal TS8 IP 20
and UL and NEMA 1 and IP 54 and UL and NEMA 12
enclosures.
CAUTION
For the E2 enclosures it is important to mount the plate
at the absolute rear of the Rittal enclosure due to the
weight of the frequency converter.
CAUTION
A doorfan(s) is required on the enclosure to remove the
heat losses not contained in the backchannel of the
frequency converter and any additional losses generated
from other components installed inside the enclosure.
The total required airflow 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 frequency
converter is the only heat generating component in the
enclosure, the minimum airflow required at an ambient
temperature of 45 °C for the D3 and D4 frequency
converters is 391 m
3
/h (230 cfm). The minimum airflow
required at an ambient temperature of 45 °C for the E2
frequency converter is 782 m
3
/h (460 cfm).

NOTICE
See the instruction Duct Work Cooling Kit Instruction for
Frames D3, D4 and E2 for further information.
External ducts
If additional duct work is added externally to the Rittal
cabinet the pressure drop in the ducting must be
calculated. See chapter 3.3.6 Cooling and Airflow for further
information.

Outside Installation/NEMA 3R Kit for
Rittal Enclosures
Illustration 3.50
This section is for the installation of NEMA 3R kits available
for the frequency converter enclosure types D3, D4 and E2.
These kits are designed and tested to be used with IP00/
Chassis versions of these enclosure types 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
enclosure type E2) and the kit is designed for a 600 mm
(800 mm for enclosure type E2) wide enclosure. Other
enclosure widths are possible, however additional Rittal
hardware is required. The maximum depth and width are
as required by the installation.
