3.4. Operating mechanism assembly
The operating mechanism should be mounted on the supporting structure, under driving crank located in dis-
connector base. After the operating mechanism is assembled, the coupling shaft must be attached to connect
the operating mechanism to the crank. The assembly method is shown in the figure below.
Tightening torque: M12 - 80 Nm, M16 - 100 Nm.
3.5. Pole coupling and adjustment
After setting the poles on the supporting structure, check the end positions of the current paths and, if neces-
sary, correct the position of the bumpers and the lengths of the shafts of the disconnector kinematic system.
After checking the correctness of operation of the poles the coupling rods can be assembled.
