Checklist before mechanical installation
The installation site
Check the installation site. See section Ambient conditions on page 113 for the allowed operating
conditions, and section Dimensions, weights and free space requirements on page 109 for the
requirements for free space around the converter.
Check that the floor that the converter is installed on is of non-flammable material, as smooth as
possible, and strong enough to support the weight of the converter.
Check the floor flatness with a spirit level. The maximum allowed deviation from the surface level is
5 mm (0.2 in) in every 3 meters (9.8 ft).
If necessary, level the installation site, as the cabinet is not equipped with adjustable feet.
Check that the wall behind the converter is of non-flammable material.
Required tools
Check that you have following tools for moving the converter to its final position, fastening it to the
floor and tightening the connections:
• crane or fork-lift (check the load capacity); iron bar and piece of planked wood
