5 Unpacking and installing the equipment
5.1 Type of Civil Engineering
The installation of a switchboard
requires a sufficiently flat and even
concrete structure. The dressing of
a top coat of cement using a rule
should eliminate any surface irregu-
larities greater than 2 mm per
metre.
A layout on iron supports for level-
ling off is ideal as they will also
serve as a guide for the adjustment
of the cement top coat.
The overall flatness of the support
surface should not show up any
deflection greater than 6 mm throu-
ghout the length of the switch-
board.
5.2 Unpacking the Functional Units
Proceed with unpacking the Functio-
nal Units only where they are to be
installed on site.
Tools required:
