I 
Below are the wiring instructions for the power supply modules of the AIS PLC. 
1.  If the fluctuations of the power supply modules incoming voltage are larger 
than  permitted  by  the  specification of  the  module,  a  constant  voltage 
transformer should be used as shown below.

2.  If the  incoming  power supply to  the  module generates noise outside the 
specifications of the power supply  module, then an  insulating transformer 
should be used as shown below.

3.  When a power transformer 
or 
insulating transformer 
is 
used to  reduce the 
voltage from 200 VAC  to  100 VAC,  use one which has a capacity greater 
than shown in the table below.
