CAUTION
• The external I/O is not capable of connecting directly to devices that
require large amounts of current. In some cases, a custom interface
circuit (customer-provided) may have to be used. Serious damage to the
camera may result if a device that exceeds its electrical capability is
connected to the external I/O (see page 164).
• Low voltage/current circuits and high voltage/current circuits are used in
the camera circuit. All wiring should be performed by a qualified
electrician. Incorrect wiring could damage the camera and cause a fatal
electric shock.
