Wiring rules and recommendations

For analog input and analog output channels, twisted-pair wiring with
shielded cable is recommended and it will improve noise immunity if
wire routing is suspect.

Wire Gauge

Observe all local codes when making power connections. Unless local
electrical codes dictate otherwise, the recommended minimum wire
size for connections is given in the following table.

Routing and securing wires

Typically, field wiring is routed to connections at a terminal panel near
the racks, and then from the terminal panel to the terminal blocks on
the I/O modules.
Whatever method of routing is used, wiring must be mechanically
supported along its length, and must be protected from physical
damage and electromagnetic (noise) interference. For more
information, see
ATTENTION:
For CE conformity, all signal wire must use shielded cable.
