3.1 General warnings and cautions
WARNING
Once the documents have been prepared for final
mounting, the binding data supplied by ABB must
always be taken into account!
WARNING
In order to obtain an optimal installation sequence
and ensure high-quality standards, on-site
installation of the switchgear must only be carried
out by specially trained and skilled personnel, or at
least by personnel supervised and monitored by
competent and responsible people
NOTE
Where switchgear units have roof-mounted gas
vent ducts or large auxiliary circuit compartments,
it must be ensured that the ceiling height is
sufficient for these
ATTENTION
The access to the Swg Room while Swb is in service
is permitted to authorized personnel only who has
specific expertise on electrical safety according to
CEI 11-27 or IEC/EN 50110
3.2 Preparations
Before starting
To commence installation on site, the switchgear
room must be absolutely suitable, i.e. provided with
lighting and electricity, fitted with a padlock,
ventilation facilities and must also be dry.
All the necessary preparations, such as wall
openings, ducts, etc. for laying the power and
control cables as far as the switchgear, must already
have been completed.
Before proceeding with installation:
a) Clean the installation site
b) Visibly trace the perimeter of all the units making
up the switchgear on the slab, taking the
minimum clearances of wall and any obstacles
into account
