I. Introduction
All the installation, putting into service, run-
ning and maintenance operations must be
carried out by suitably qualified personnel
with in-depth knowledge of the apparatus.
This publication contains the information required for installing
and putting the following medium voltage circuit-breakers into
service: HD4/R, HD4/S, HD4/UniAir, HD4/UniMix, HD4/R-SEC.
Please read the manual carefully to ensure that the product is
used correctly.
Refer to the relative instructions in order to assemble the ac-
cessories and/or spare parts correctly.
Similarly to all the apparatus we manufacture, the HD4/R,
HD4/S, HD4/UniAir, HD4/UniMix, HD4/R-SEC circuit-breakers
are also designed for different installation configurations.
However, these devices can be subjected to 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 con-
cerning special customized configurations.
Besides 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 standard configurations.
Only use original spare parts for maintenance operations.
Please also consult the technical catalogue of the circuit-
breaker and the spare parts catalogue for further details.
