Terminal box

*1: The Ln dimension means a length from the set position to the bottom of the screw.
*2: The L dimension means the total length from the bottom of the screw.
*3: Setting distance dimensions refers to the minimum dimension when two stoppers are used.
*4: The L-Ln dimension refers to the difference between the final setting position (Ln) and total length.
Note: The values for *3 and *4 are true when the specific gravity of the liquid is 1.0.
