Terminal blocks
Terminal blocks are wired to the field devices, attached to the front sockets of the I/O modules,
and tightened using the side screws. Terminal blocks can come in the form of screw terminals,
front screw terminals, or spring terminals. Use blue terminal blocks for intrinsically safe circuits.
Use black terminal blocks for non-intrinsically safe circuits that comply with type of protection

the requirements for wire end ferrules according to DIN 46228-1 and DIN 46228-4.
n
Use only one conductor per terminal.
n
Observe the requirements for stripping conductor insulation for Ex e protection according
to IEC/EN 60028.
n
Observe the tightening torque for the screws on the terminal.
