ABB hd4 Installation And Service Instructions Manual page 4

I. Introduction
This publication contains the information necessary for
installation and putting into service of HD4 medium voltage
circuit-breakers.
For correct usage of the product, please read this manual
carefully.
For correct mounting of accessories and/or spare parts
please refer to the relevant instructions.
Like all the apparatus manufactured by us, the HD4 circuit-
breakers are designed for different installation configurations.
They do, however, allow further technical-constructional
variations (at the customer's request) to suit special
installation requirements.
For this reason, the information given below does not always
cover special configurations.
Apart from this booklet, it is therefore always necessary to
refer to the latest technical documentation available (circuit
diagram, wiring diagrams, assembly and installation drawings,
any studies of protection co-ordination, etc.), especially with
regard to any variations from standardized configurations
requested.
All the operations regarding installation, putting
into service, operation and maintenance must be
carried out by suitably qualified personnel with in-
depth knowledge of the apparatus.
Only use original spare parts for maintenance operations.
For further information, also see the technical catalogue of the
circuit-breaker and the spare parts catalogue.

II. Programme for the environmental
protection
The HD4 circuit-breakers comply with ISO 14000 Standards
(Guidelines for the Environmental Management).
The production system of the Medium Voltage factories
complies for the environmental protection in terms of energy
consumption, raw materials and waste.
The environmental impact of the product life cycle is assessed
by the LCA - Life Cycle Assessment procedure, which is also
the result of a well-focused project phase in the selection of
materials, processes and packaging.
The Product environmental declaration is available for the
HD4 circuit-breakers
Production techniques are carried out in order to achieve
an easy dismantling and separation of the components at
the end of the circuit-breaker life cycle, while optimizing the
recycling process.
