NFI-U08-1 with 3-Pin Terminal Block

Note: 

The 3-Pin Terminal Block is integrated to switch case. The NFI-U08-1 is 

designed to face forward and requires more space. It utilizes a different type of 
terminal block (gray color) commonly known as a PCB terminal block, as it is directly 

mounted in the PCBA. The NFI-U08-1 model does not require an additional male 
connector like the NFI-U05 and NFI-U08-2 models.

Check the polarity while connecting. Top view of the Terminal Block is shown 
in the figure below:
