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
the camera may result if a device is connected to the external I/O that
exceeds its electrical capability (see page 119).
• The low voltage/current circuits and high voltage/current circuits are
in the camera circuit. The qualified electrician should do the wiring
not by yourself. Incorrect wiring could damage the camera. You
could receive the fatal electric shock.
