● Terminal Block Connection Method
Using Crimp Terminals
(1) Use ferrules or tab terminals.
However, the Terminal Blocks are small, so sufficiently confirm
the following before you use them.
(2) Insulation between Crimp Terminals
If you use naked crimp terminals, there will be no finger protection.
Also, there will be limited clearance and creepage distances
between adjacent terminals, so use crimp terminals with care.
