3 VLT Automation VT Drive Selection
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.
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 door-fan(s) is required on the Rittal cabinet to remove the loses not contained in the back-channel of the drive. The minimum door-
fan(s) airflow required at the drive maximum ambient for the D3 and D4 is 391 m^3/h (230 cfm). The minimum door-fan(s) airflow
required at the drive maximum ambient for the E2 is 782 m^3/h (460 cfm). If the ambient is below maximum or if additional compo-
nents, heat loses, are added within the enclosure a calculation must be made to ensure the proper airflow is provided to cool the inside
of the Rittal enclosure.

frequency converter according to the pressure drop.
