CAUTION

•The external I/O is not capable of connecting directly to devices that
require large amounts of current. In some case, a custom interface
circuit (customer-provided) may have to be used. Serious damage to
this product may result if a device is connected to the external I/O
that exceeds its electrical capability (see page 143).
•The low voltage/current circuits and high voltage/current circuits are
in the circuit. The qualified electrician should do the wiring not by
yourself. Incorrect wiring could damage this product. You could
receive the fatal electric shock.
