I. Introduction
This publication contains the information needed
to install medium voltage VM1 circuit breakers and
put them into service.
For correct use of the product, please read it
carefully.
Like all the apparatus we manufacture, the VM1
circuit breakers are designed for different
installation configurations.
However, they do allow further technical and
construction modifications (at the customer's
request) to adapt to special installation
requirements.
For this reason, the information given below may
sometimes not contain instructions concerning
special configurations.
Apart from this manual, it is therefore always
necessary to consult the latest technical
documentation (circuit and wiring diagrams,
assembly and installation drawings, any
protection coordination studies, etc.), especially
regarding any variants requested in relation to the
standardised configurations.
Only use original spare parts for maintenance
operations.
For further information, please also see the
technical catalogue of the circuit breaker.
All the installation, putting into service,
running and maintenance operations
must be carried out by skilled personnel
with in-depth knowledge of the
apparatus.
