How to Install

3.2 Mechanical Installation

Preparation of the mechanical installation of the frequency
converter must be done carefully to ensure a proper result
and to avoid additional work during installation. Start
taking a close look at the mechanical drawings at the end
of this instruction to become familiar with the space
demands.

3.2.1 Tools Needed

To perform the mechanical installation the following
tools are needed:
•
Drill with 10 or 12 mm drill
•
Tape measure
•
Wrench with relevant metric sockets (7-17mm)
•
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 max. Ø 5
mm (1 inch), able to lift minimum 400 kg (880
lbs)).
•
Crane or other lifting aid to place the frequency
converter in position
•
A Torx T50 tool is needed to install the E1 in IP21
and IP54 enclosure types.

3.2.2 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, i.e. by using cable clamps.
CAUTION
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.
