In any case, avoid stressing the supporting structure of the contactor: if necessary, arrange slots in the fixing area to facilitate correct positioning of the apparatus. The assembly positions can be selected between the two shown in figure 4b. VSC7 (1) The width of the contactor varies based on the presence of the interfacing shafts.

However, even earthing carried out correctly is not a sufficient measure to ensure a good connection between the VSC control module and earth. In fact, since the control module of the contactor is connected to the metallic base of the VSC by means of a copper connection (Fig. 7), it is always necessary to check that the connection is intact.
