The - 5 V is used to delay starting of the

external DC-to-DC converter on camera

power-on, so as to prevent tripout of the

Channel Control Unit power supply. This

should be used for this application only.

If a DC-to-DC converter is connected (even

without load) to a camera in operation, the

safety system will cause the camera circuit-

breaker to trip.

The converter connections must be made

with the camera power off.
