Pedestal Installation Of F-Frames; Safety Requirements Of Mechanical Installation - Danfoss VLT AQUA Drive FC 202 Design Manual

How to Install

5.1.3 Pedestal Installation of F-frames

The F-frame frequency converters are shipped with a
pedestal. The F-frame pedestals use 8 bolts instead of 4, as
shown in Illustration 5.3.
Illustration 5.3 Pedestal Bolt Installation
To install a pedestal-mounted F-frame unit, perform the
following steps:
1. If using a kit to direct the airflow from the heat
sink to the outside vent on the back of the
frequency converter, verify there is a minimum of
100 mm ceiling clearance.
2. Install each M8x60 mm bolt with lock washer and
flat washer through the frame into the threaded
hole in the base. Install 4 bolts per cabinet. Refer
to Illustration 5.4
3. Install each M10x30 mm bolt with captive lock
washer and flat washer through the base plate
and into the threaded hole in the base. Install 4
bolts per cabinet. Refer to Illustration 5.4

5.1.4 Safety Requirements of Mechanical
Installation
CAUTION
To avoid serious injury or equipment damage, observe
the information in the field mounting and integration
kits, especially when installing large units.
CAUTION
The frequency converter is cooled with air circulation.
To protect the unit from overheating, ensure that the
ambient temperature does not exceed the maximum
rated temperature. If the ambient temperature is in the
range of 45–55 °C, derating of the frequency converter is
relevant. See chapter 8.5.5 Derating for Ambient
Temperature.
Failure to consider derating for ambient temperature can
reduce the service life of the frequency converter.
