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
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).

Table 3.10 Ordering Information
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 3.2.6 Cooling and Airflow
for further
information.
3.3.2 Installation of Top-only Duct Cooling
Kit
This description is for the installation of the top section
only of the back-channel cooling kits available for frame
sizes D3, D4 and E2. In addition to the enclosure a 200
mm vented pedestal is required.
The minimum enclosure depth is 500 mm (600 mm for E2
frame) and the minimum enclosure width is 600 mm (800
mm for E2 frame). The maximum depth and width are as
required by the installation. When using multiple
frequency converters in one enclosure mount each
frequency converter on its own back panel and support
along the mid-section of the panel. The back-channel
cooling kits are very similar in construction for all frames.
The D3 and D443 and 44 kits do not support “in frame”
mounting of the frequency converters. The E2 kit is
mounted “in frame” for additional support of the
frequency converter.
Using these kits as described removes 85% of the losses
via the back channel using the frequency converter’s main
heat sink fan. The remaining 15% must be removed via the
door of the enclosure.
NOTICE
See the
Top-Only Back-Channel Cooling Kit Instruction,
175R1107,
for further information.

3.3.3 Installation of Top and Bottom Covers
for Rittal Enclosures
The top and bottom covers, installed onto IP00 frequency
converters, direct the heat sink cooling air in and out the
back of the frequency converter. The kits are applicable to
IP00 frequency converterframes D3, D4 and E2. These kits
are designed and tested to be used with IP00/Chassis
frequency converters in Rittal TS8 enclosures.
Notes:
1.
If external duct work is added to the exhaust
path of the frequency converter, additional back
pressure reduces the cooling of the frequency
converter. The frequency converter must be
derated to accommodate the reduced cooling.
First, the pressure drop must be calculated, then
refer to the derating tables located earlier in this
section.
2.
A doorfan(s) is required on the enclosure to
remove the heat losses not contained in the
backchannel of the frequency converter and any
