This publication contains the information required
to install VD4G medium voltage circuit-breakers
and put them into service.
Please read the manual carefully to ensure that the
product is used correctly.
Similarly to all the apparatus we manufacture,
VD4G circuit-breakers are designed for different
installation configurations.
They can therefore undergo further technical-
construction modifications (at the customer’s
request) so as to adapt them to special installation
requirements.
Consequently, the manual may not contain
instructions concerning special customized
configurations.
This means that, besides this manual, it is always
necessary to consult the latest technical
documentation (circuit and wiring diagrams,
layouts, assembly and installation drawings, any
protection coordination studies, etc.), especially
regarding any variants requested in relation to the
standard configurations.
Only use original spare parts for maintenance
operations.
Please also consult the technical catalog of the
circuit-breaker and the spare parts catalog for
further details.
All the installation, putting into service,
running and maintenance operations
must be carried out by suitably
qualified personnel with in-depth
knowledge of the apparatus.

II. Environmental
protection program
VD4G circuit-breakers are manufactured in
accordance with ISO 14000 Standards (Guidelines
for environmental management).
The manufacturing processes are implemented in
accordance with the environmental protection
standards when it comes to reducing both energy
consumption and the production of waste. All this
is thanks to the environmental management
system applied in the medium voltage apparatus
manufacturing facility.
