3. INSTALLATION AND ADJUSTMENT
3.1. Coupling with disconnectors HV
For coupling operating mechanism to disconnectors a coupling shaft with a joint is used. The end of the shaft
is adapted to a particular type of apparatus. The operating mechanism is attached to the lattice structures
which are adapted to the customer's needs.
3.2. Protective earthing connection
The operating mechanism's grounding is achieved by using the earthing point placed on the back of the oper-
ating mechanism, shown on the dimensional sketch, consisting of an M12 screw and a washer. The cross-sec-
tion of the rail connecting the operating mechanism to the switchgear's groundings should be selected in ac-
cordance with applicable regulations. Prior to connecting protective grounding to the housing of the operating
