Any transport damage must be reported to the

the switchgear is to be made immediately after

delivery, the transport packing must be removed,

except for the plastic vapour corrosion inhibitor

film covering the units, which must only be

removed at the final switchgear installation site

2.3 Handling the units as far as

the installation site

2.3.1 General warnings and cautions

DANGER

Only carry out loading operations when it has been

ensured that all precautionary measures to protect

personnel and materials have been taken

CAUTION

The switchgear units should usually be handled in

an upright position. Take the high centre of gravity

into account. Tilting or overturning must be

avoided. If necessary, single units can be carried

horizontally, for example, because of a low

doorway. In such cases, the unit must be supported

over a wide area

2.4 Temporary storage

2.4.1 General warnings and cautions

CAUTION

The packing must be kept indoors immediately

after arrival. The conditions must meet the

environmental requirements of the IEC 60721-3-1

Standard, classification 1K3

CAUTION

The vapour corrosion inhibitors placed in the units

for protection against humidity during temporary

storage and transport must not be removed until

installation is completed

CAUTION

The duration of the protective effect of the packing

is limited to a few months when stored indoors in a

dry place. ABB should be consulted in the case of

longer storage periods or if the storage conditions

differ from those indicated

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
