3.4 Field Installation of Options
3.4.1 Installation of Duct Cooling Kit in Rittal Enclosures
This section deals with the installation of IP00 / chassis enclosed adjustable frequency drives with duct work cooling kits in Rittal enclosures. In addition
to the enclosure, an 8 in [200 mm] base/plinth is required.
Figure 3.27: Installation of IP00 in Rittal TS8 enclosure
The minimum enclosure dimension is:
•
D3 and D4 frame: Depth 19.7 in [500 mm] and width 23.6 in [600 mm].
•
E2 frame: Depth 23.6 in [600 mm] and width 31.5 in [800 mm].
The maximum depth and width are as required for the installation. When using multiple adjustable frequency drives in one enclosure, it is recommended
that each drive be 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 catalog for details). The duct work cooling kits listed in the table below are suitable for use only with IP 00/chassis
adjustable frequency drives in Rittal TS8 IP 20 and UL and NEMA 1 and IP 54 and UL and NEMA 12 enclosures.
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 adjustable
frequency drive.
NOTE!
A door fan or fans are required on the Rittal cabinet to remove the losses not contained in the backchannel of the drive. The minimum
door fan airflow required for the D3 and D4 is 391 m^3/h (230 cfm). The minimum door fan airflow required for the E2 is 782 m^3/
h (460 cfm). If additional components or heat losses are added to the enclosure, a calculation must be made to ensure the proper
airflow is provided to cool the inside of the Rittal enclosure.
