6 Mechanical Installation

6.1 Pre-installation

NOTICE
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 criteria:
•
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
For more detail, see the following pages in this chapter.

6.1.1 Receiving the Frequency Converter

When receiving the frequency converter, make sure that
the packaging is intact, and be aware of any potential
damage to the unit during transport. If damage has
occurred, contact the shipping company immediately to
claim the damage.
Also, look at the nameplate as shown in Illustration 6.1 and
verify the order matches the information found on the
nameplate.

6.1.2 Transportation and Unpacking

Before unpacking the frequency converter, position it as
close as possible to the final installation site. Remove the
box and leave the frequency converter on the pallet until
ready for installation.

6.1.3 Lifting

Lift the frequency converter using the dedicated lifting
eyes. For all E2 (IP00) enclosures, use a bar to avoid
bending the lifting holes of the frequency converter.
The following illustrations demonstrate the recommended
lifting methods for the different frame sizes. In addition to
Illustration 6.4, Illustration 6.5, and Illustration 6.6, a spreader
bar is an acceptable way to lift the F-frame.
WARNING
The lifting bar must be able to handle the weight of the
frequency converter. See 6.1.4 Mechanical Dimensions for
the weight of each frame size. Maximum diameter for
the bar is 2.5 cm (1 inch). The angle from the top of the
drive to the lifting cable should be 60° or greater.
