3.4.3. Installation on pedestal

This section describes the installation of a pedestal unit available for the
VLT series frequency converters frames D1 and D2. This is a 200 mm high
pedestal that allows these frames to be floor mounted. The front of the
pedestal has openings for input air to the power components.
The frequency converter gland plate must be installed to provide ade-
quate cooling air to the control components of the frequency converter
via the door fan and to maintain the IP21/NEMA 1 or IP54/NEMA 12 de-
grees of enclosure protections.
There is one pedestal that fits both frames D1 and D2. Its ordering number is 176F1827. The pedestal is standard for E1 frame.
