ABB V-Contact VSC Series Installation And Service Instructions Manual page 5

I. Introduction
The instructions in this manual refer to the fixed and withdrawable versions of the VSC series of
contactors. For correct use of the product, please read it carefully.
For the electrical and construction characteristics and the overall dimensions of the V-Contact
VSC contactors, please also see technical catalogue 1VCP000165.
Like all the apparatus we manufacture, the V-Contact vacuum contactors are designed for differ-
ent installation configurations. Furthermore, this apparatus allows further technical and con-
struction modifications (at the customer's request) to adapt to special installation requirements.
Consequently, this manual may not provide information concerning special configurations of the
apparatus.
Apart from this manual, it is therefore always necessary to consult the latest technical documen-
tation (circuit and wiring diagrams, assembly and installation drawings, any protection coordina-
tion studies, etc.), especially regarding any variants requested in relation to the standardised
configurations.
Only use original spare parts for maintenance operations. The use of non-original spare parts
can cause hazardous malfunctions and the apparatus warranty will no longer be valid.
Please refer to the technical sheets of the Kits for correct assembly of the accessories and/or
spare parts. For further information, also see the 1VCP000165 technical catalogue of the contactor
and the spare parts catalogue.
This manual and all the enclosed drawings must be considered an integral part of the apparatus.
They must be easily to hand at all times for revision and reference.
These instructions do not intend to cover all the details, configurations or variants of the appara-
tus, storage or installation. For this reason, the information given below may sometimes not
contain the instructions regarding special configurations. This does not relieve the user from
their responsibility for using good technical working practices in application, installation, service
and maintenance of the apparatus purchased. Should further information be required, please
contact ABB.

WARNING
Dangerous voltages. Risk of death, serious injury to people, damage to
the apparatus or other objects.
Before carrying out any maintenance operations, turn the power supply off
and earth the apparatus. Read and understand this instruction manual
before installation, service or maintenance of the apparatus.
Maintenance must only be carried out by skilled personnel. The use of
unauthorized spare parts for repairs to the apparatus, modification of the
apparatus itself, or any tampering by unskilled personnel creates hazardous
conditions which may cause death or serious injury to people, or damage to
the apparatus or other objects. Carefully follow all the safety instructions
given in this manual.
