3.3 Field Installation of Options

3.3.1 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 unit
sizes 43, 44 and 52. In addition to the enclosure a 200 mm
vented pedestal is required.
The minimum enclosure depth is 500 mm (600 mm for
unit size 52) and the minimum enclosure width is 600 mm
(800 mm for unit size 52). The maximum depth and width
are as required by the installation. When using multiple
frequency converters in one enclosure mount each drive
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 kits do not support "in
frame" mounting of the frequency converters. The 52 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 drive's main heat sink fan.
The remaining 15% must be removed via the door of the
enclosure.
