4.3 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.
4.3.1 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/Nema 1 and IP 54 units
• Lifting bar to lift the unit (rod or tube max. Ø 25 mm (1 inch), able to lift minimum 1000 kg).
• 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.
4.3.2 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.
