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.

3.3.1. 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 (7-17 mm)

•

Extensions to wrench

•

Sheet metal punch for conduits or cable glands in IP 21 and IP 54 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

•

A Torx T50 tool is needed to install the E1 enclosure in IP21 and IP54 enclosure types.

3.3.2. General Considerations

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.

Illustration 3.8: Space in front of IP21/IP54 enclosure type D1 and D2.

NB!

Airflow direction, see

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.

NB!

All cable lugs/ shoes must mount within the width of the terminal bus bar
