Checklist before mechanical installation
The installation site
Check the installation site. See the technical data for the allowed operating conditions and for the re-
quirements 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
• Pozidriv and Torx (2.5 ... 6 mm, 0.98 ... 0.2 in) screwdrivers for the tightening of the frame screws
(Screws needed for fastening the cabling boxes and other accessories delivered by ABB are included
in the delivery. They are inside the cabinet. The delivery does not contain screws or tools to install
the cabinet to the floor.)
• torque wrench
• set of wrenches and sockets.
