Mechanical Installation

6.2 Mechanical Installation
Preparation for the mechanical installation of the
frequency converter must be done carefully to ensure a
proper fit and to avoid additional work during installation.
The mechanical drawings in 6.1.4 Mechanical Dimensions
provide more information about the space requirements.

6.2.1 Tools Needed

To perform the mechanical installation, the following
tools are needed:
•
Drill with 10 mm or 12 mm drill bits.
•
Tape measurer.
6 6
•
Wrench with relevant metric sockets (7–17 mm).
•
Wrench extensions.
•
Sheet metal punch for conduits or cable glands
in IP21 (NEMA 1) and IP54 (NEMA 12) units.
•
Lifting bar to lift the unit (rod or tube max. Ø 25
mm (1 inch), able to lift minimum 400 kg (880
lbs)).
•
Crane or other lifting aid to place the frequency
converter in position.
•
Use a Torx T50 tool to install the E1 in IP21 and
IP54 enclosure types.

6.2.2 General Considerations

Wire Access
Ensure that proper cable access is present including
necessary bending allowance. As the IP00 enclosure is
open to the bottom, cables must be fixed to the back
panel of the enclosure where the frequency converter is
mounted.
NOTICE
All cable lugs/shoes must mount within
the width of the terminal bus bar.
Space
Ensure proper space above and below the frequency
converter to allow airflow and cable access. In addition,
space in front of the unit must be considered to enable
opening of the door of the panel.
