INSTALLATION OF BACK-CHANNEL COOLING KIT FOR FRAMES D3, D4 & E2

This instruction sheet is for the installation of back-channel cooling kits available for the VLT

series drives. These kits are designed and tested to be used with Rittal TS8 enclosures

1800, 2000 and 2200 mm in height. Other enclosure heights are not supported. In addition to

the enclosure a 200 mm vented base/plinth is required.

The minimum enclosure depth is 500 mm (600mm for E2 frame) and the minimum enclosure

width is 600 mm (800mm for E2 frame). The maximum depth and width are as required by

the installation. When using multiple drives in one enclosure mount each drive on its own

back panel and support along the mid-section of the panel. The ductwork kits are very similar

in construction for all frames. The D3 and D4 kits do not support "in frame" mounting of the

drives. The E2 kit is mounted "in frame" for additional support of the drive. These kits can be

used with IP00/ Chassis drives as listed in Table 1 and are suitable for use only with Rittal

TS8 IP20 and UL & NEMA 1 and IP54 and UL & NEMA 12 enclosures.

Using these kits as described removes 85% of the losses via the back channel using the

drive's main heat sink fan. The remaining 15% must be removed via the door of the Rittal

enclosure. (Refer to Note 2 on Page 2 for air flow requirements.)
