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 (7-17mm)
• Extensions to wrench
• Sheet metal punch for conduits or cable glands in IP 21/Nema
1 and IP 54 units

3.3.2 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.
NB!
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.
