3.
If you are using stranded conductors, crimp the stranded conductors
with wire end ferrules.
4.
Make sure that the insulation on the conductors extends all the way to
the terminal.
5.
Make sure that the separation distances to non-intrinsically safe circuits
are observed.
6.
Unused cables and connection lines must be connected to terminals,
securely fixed and isolated, or grounded.
7.
If necessary, you can code the front sockets of the I/O modules and
terminals so that the terminals and the associated field devices can be
assigned to exactly one front socket.
8.
Plug the terminals into the front sockets of the corresponding I/O
modules and screw the terminals into place using the side screws.
9.
Label the connection lines.
Coding
You can code the front sockets
(1)
and the terminals of the I/O modules so that
the terminals and the connected field devices can be assigned to exactly one
front socket.
Use coding pins 1719-CP.
Coding Connections
1.
To code the front socket of an I/O module, insert one or more coding
pins into the corresponding grooves on the front socket.
(1)
Not applicable for 1718-IBN8 Ex I/O 8 Point Digital Input module.
WARNING:
If the coding is not unique, terminals can be accidentally mixed up.
Establish a clear coding so that every terminal fits exactly one front socket.
