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
