Wiring AC I/O Modules

This section explains how to connect a power supply cable and an I/O signal cable
to an AC I/O Module.
a) As shown in Examples 1 and 2 later in this section, it is necessary to supply external
single-phase AC power (100 or 200VAC) to the AC I/O Modules listed in the follow-
ing table to power input signals and drive loads.

b) Use a low-noise AC power supply. If noise is a problem, use an insulation trans-
former or a noise filter.
c) Heed the following precautions when supplying AC power.
Connect power supplies of the same phases to the common 1 and common 2 of the
AC I/O Module.
If power supplies of different phases are connected, overheating or fire may
occur.
d) Heed the following precautions when mounting or removing Modules while the
power is being supplied. For a description of hot swapping and for an example of
safety switch settings, refer to 7.2 Hot Swapping.
When inserting or removing an AC I/O Module while the AC power supply is turned
ON, install a safety switch for each Module and always turn this safety switch OFF to
turn OFF the AC power supply to the Module.
Inserting or removing an AC I/O Module while AC power is being supplied may
result in an electric shock at touching the power supply terminals.
