6.2.2 Anchoring systems
The switchboard can be fixed either to the
floor or to special foundation frames (supplied
on request).
Usually four fixing holes are drilled in each unit
base (confirm with the general arrangement
drawing).
Before positioning the different switchboard
units, check both the flatness of the floor, with
particular attention to longitudinal leveling
(maximum planarity 2/1000).

6.2.3 Fixing with anchoring bolts to concrete
floor:
•
Clean the installation area
•
On the slab, visibly trace the perimeter of all
the units making up the switchboard, taking
the minimum wall and obstacle clearances
into account
•
Level the floor both longitudinally and
transversally
•
Drill the floor at the foreseen fixing points,
referring to the slab drilling drawings. To
make the holes, use a hammer drill
•
Insert the expansion anchoring bolts in the
holes
6.2.4 Fixing with anchoring bolts to floor frames
The floor frames, which can be supplied on
request, must be installed in the slab before
finishing the floor.
Check the panel fixing points correspond to
the positions shown in the floor plans on the
General Arrangement drawing.
6.3 Prepare switchgear panels
The individual installation stages are as
follows:
•
Remove the withdrawable fused contactor
from the switchgear panels and store them
with suitable protection. Observe the
interlocks and operation sequences when
removing it
•
Transport the switchgear panels to the
prepared installation point following the
layout shown on the general arrangement
drawing
•
Remove the lifting lugs after the panels are in
their final position. Refit the hardware after
removing the lifting lugs. It is advisable to
start from the centre of the switchboard or
the bus-section panel when there are more
than 10 panels
•
When the switchgear has been properly
assembled, fix the panels to the concrete
floor using expansion anchoring bolts, or
weld or adequately bolt them to the
foundation frame
6.4 Join panels
Remove the Rear Cover of the panel and the
parts shown from the front to facilitate the
joining of the panels.
