5. Installation
5.1. General
Correct installation is of primary importance. The
manufacturer’sinstructionsmustbecarefullystudiedand
followed. It is good practice to use gloves for handling the
pieces during installation.
The areas involved in the passage of power
conductors or conductors of auxiliary
circuits must be protected against access of
any animals which might cause damage or
disservices.

sure that there is a heating element to keep the humidity
down and of suitable size for the compartment where the
contactor is installed. The contactor must always be installed

The fixed version of the V-Contact VSC
contactors must be installed by the customer
so as to guarantee a minimum degree of
protection of IP2X.
5.2. Installation and operating
conditions
The following Standards must be taken into particular
consideration during installation and service:
– IEC62271-1/DIN VDE 0101
– VDE 0105: Operation of electrical plants
