6.Interlock
6.1 Load switch and ground switch, ground switch and front door (with interlock for matching cabinet) all have reliable mechanical interlock. The operating sequence is as the following:
 

1. The load switch is at the closing position and the ground switch operating hole is blocked;
2. After the load switch is divided, the ground switch can be closed or the load switch can be closed.
3. After the grounding switch is closed, the interlock with the front door of the cabinet is removed, the operating hole of the load switch is blocked, and the cabinet door can be opened;
4. The load switch is locked in the front door of the cabinet in the position of closing and closing.

6.2 When there is no grounding switch, the operating hole of the grounding switch is the interlock operating hole of the front cabinet door. The operating sequence is:
a)  When the load switch is divided, the door interlock operation can be carried out;
b) Door interlock operation clockwise rotation of the front door unlock;
c) Door interlock operation clockwise rotation of the front door lock;
