How to Install

3.2 Mechanical Installation

3.2.1 Preparation for Installation

To ensure reliable and effective installation of the
3 3 frequency converter, make the following preparations:
•
Provide a suitable mounting arrangement. The
mounting arrangement depends on the design,
weight, and torque of the frequency converter.
•
To ensure that the space requirements are met,
examine the mechanical drawings.
•
Ensure that all wiring is done in accordance with
national regulations.

3.2.2 Tools Required

•
Drill with 10 mm or 12 mm bit.
•
Tape measure.
•
Wrench with relevant metric sockets (7–17 mm).
•
Extensions to wrench.
•
Sheet metal punch for conduits or cable glands in
IP21/NEMA 1 and IP54 units
•
Lifting bar to lift the unit (rod or tube maximum
Ø 25 mm (1 in), able to lift minimum 400 kg (880
lb).
•
Crane or other lifting aid to place the frequency
converter in position.

3.2.3 General Considerations

Space
To allow airflow and cable access, ensure sufficient space
above and below the frequency converter. In addition,
allow for enough space in front of the unit to open the
panel door, see Illustration 3.5 to Illustration 3.12.
