7 Mechanical Installation - Frame size D, E and F

7.1 Pre-installation

7.1.1 Planning the Installation Site

CAUTION
Before performing the installation it is important to plan
the installation of the frequency converter. Neglecting this
may result in extra work during and after installation.
Select the best possible operation site by considering the
following (see details on the following pages, and the
respective Design Guides):
•
Ambient operating temperature
•
Installation method
•
How to cool the unit
•
Position of the frequency converter
•
Cable routing
•
Ensure the power source supplies the correct
voltage and necessary current
•
Ensure that the motor current rating is within the
maximum current from the frequency converter
•
If the frequency converter is without built-in
fuses, ensure that the external fuses are rated
correctly.

7.1.2 Receiving the Frequency Converter

When receiving the frequency converter please make sure
that the packaging is intact, and be aware of any damage
that might have occurred to the unit during transport. In
case damage has occurred, contact immediately the
shipping company to claim the damage.

7.1.3 Transportation and Unpacking

Before unpacking the frequency converter it is
recommended that it is located as close as possible to the
final installation site.
Remove the box and handle the frequency converter on
the pallet, as long as possible.

7.1.4 Lifting

Always lift the frequency converter in the dedicated lifting
eyes. For all D and E2 (IP00) enclosures, use a bar to avoid
bending the lifting holes of the frequency converter.
Illustration 7.1 Recommended Lifting Method, Frame Sizes D and
E.
The lifting bar must be able to handle the weight of the
frequency converter. See Mechanical Dimensions for the
weight of the different frame sizes. Maximum diameter for
bar is 2.5 cm (1 inch). The angle from the top of the drive
to the lifting cable should be 60°C or greater.
