• EN61131-2
1) Differences from Standard Modules
The I/O Modules differ from the standard Modules in the following items.
• Removable terminal block
2) Conditions Low Voltage Directive
The following conditions must be satisfied to conform to the Low Voltage Directive.
a) Terminal block
• Use terminal blocks that are certified as the Low Voltage Directive compliant
products.
• The terminal blocks of the I/O Modules complies with the Low Voltage Directive.
To identify these terminal blocks, the shape of the field wiring terminals and the
color of the terminal block mounting screws are different from standard terminal
blocks as shown in the following table.
Note:
For the field wiring terminals, make sure to use the terminal block provided
with the product.
