Illustration 3.42: Installation of IP00 in Rittal TS8 enclo-
sure.
The minimum enclosure dimension is:
•
D3 and D4 frame: Depth 500 mm and width 600 mm.
•
E2 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 recom-
mended that each drive is mounted on its own back panel and suppor-
ted 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 suit-
able 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!
For the E2 frames it is important to mount the plate
at the absolute rear of the Rittal enclosure due to the
weight of the frequency converter.
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 cal-
culations (i.e. Rittal Therm software). If the VLT is
the only heat generating component in the enclo-
sure, the minimum airflow required at an ambient
temperature of 45
°
C for the D3 and D4 drives is 391
m
3
/h (230 cfm). The minimum airflow required at an
ambient temperature of 45
°
C for the E2 drive is 782
m
3
/h (460 cfm).
