4.6 I/O wiring

· Refer to sections 2.4 and 3 for instructions on how to properly wire the I/O terminals.
· 0.75 mm2 (18 AWG) to 0.3 mm2 (22 AWG) wires are recommended for I/O signals.
· Separate the I/O signal cables from high-power cables by at least 200 mm.
· If expansion rack or unit is used, separate the expansion cable from the power and I/O
signal cables by or unit at least 50 mm.
· It is recomm ended t o separate the input signal cables fr om out put signal cables.
!CAUTION 1. Turn off power before wiring to minimize the risk of elect r ical shock.
2. Exposed conductive parts of wire can cause electrical shock. Use
crimp-style terminals with insulating sheath or insulating tape to cover the
conductive parts. Also close the terminal covers securely on the terminal
blocks when wiring has been completed.
3. T ur n off power before removing or r eplacing units, m odules, terminal
blocks or wires. Failure to do so can cause electrical shock or damage to
the T1/ T1S and related eq uipm ent.
