I. Introduction
This publication contains the information needed to install medium
voltage VD4 circuit-breakers and put them into service.
For correct use of the product, please read it carefully.
Like all the apparatus we manufacture, the VD4 circuit-breakers are
designed for different installation configurations.
However, this apparatus allows fur ther technical-construction
modifications (at the customer’s request) to adapt to special installation
requirements.
Consequently, 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 (electric 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 and the spare parts catalogue.
All the installation, putting into service, running and
maintenance operations must be carried out by skilled
personnel with in-depth knowledge of the apparatus.
II.
Environmental protection programme
The VD4 circuit-breakers are manufactured in accordance with the
ISO 14000 Standards (Guidelines for environmental management).
The production processes are carried out in compliance with the
Standards for environmental protection in terms of reduction in energy
consumption as well as in raw materials and production of waste
materials. All this is thanks to the medium voltage apparatus
manufacturing facility environmental management system.
