Before beginning the installation, consult all design
drawings provided in the Quality Dossier and
ensure that you have all of the needed equipment
(MCC sections, fastener hardware to connect
sections and shipping split connection hardware)
and make a final check that it is in good condition.
If there is any evidence of damage to the
equipment, contact your ABB representative to
evaluate the condition of the equipment before
proceeding with installation.
Carefully review all supplied project drawings to
familiarize yourself with the layout and
construction of the MCC. After understanding the
dimensional drawings as well as the place where
the MCC will be installed, make the work plan and
verify that it has all the necessary equipment to
carry out the work of the handling for the transport
of the MCC.
Based on the footprint shown on the general
arrangement drawings, make marks on the floor
for all drilled holes necessary to fasten the MCC or
base frame to the floor, and for cable conduits (if
applicable). See the Fastening Sections to a Base
Frame section in this manual
Installation location requirements
