13. “A” = “C” + “D”
14. The value of “B” can be calculated from the value of “A” and the leaves opening angle. Ex. If “A”=160mm with the leaves
opening angle of 100 degrees, then the value of “B” is approximate 190mm.
**Please make sure “B” and “A” are similar or the same in value that the leaves can be operated smoothly, also to reduce the
burden of the motor.

6. Place the leaves in the closed position.
7. Refer to the distance of “B” in Figure 17, place the rear
plate in the correct position on the mounting surface.
Inspect if the distance is proper as shown in Figure 23
i.e. the position the front plate of the motor to be
installed.
