I. Introduction - ABB VD4 36 Installation And Service Instructions Manual

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 further 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.

1. Packing and transport
The circuit-breaker is shipped in special packing, in the open
position and with the spring discharged.
Each piece of apparatus is protected by a plastic cover
to prevent any infiltration of water during the loading and
unloading stages and to keep the dust off during storage.
2. Checking on receipt
Before carrying out any operation, always make
sure that the operating mechanism spring is
discharged and that the apparatus is in the open
position.
On receipt, check the state of the apparatus, integrity of the
packing and correspondence with the nameplate data (see
fig. 1) with what is specified in the order confirmation and in
the accompanying shipping note.
Also make sure that all the materials described in the shipping
note are included in the supply.
Should any damage or irregularity be noted in the supply
on unpacking, notify ABB (directly or through the agent or
supplier) as soon as possible and in any case within five days
of receipt.
The apparatus is only supplied with the accessories specified
at the time of ordering and validated in the order confirmation
sent by ABB.
The accompanying documents inserted in the shipping
packing are:
– instruction manual (this document)
– test certification
– identification label
– copy of the shipping documents
– electric wiring diagram.
Other documents which are sent prior to shipment of the
apparatus are:
– order confirmation
– original shipping advice note
– any drawings or documents referring to special
configurations/conditions.
