Converter supply:

The voltage received on this receptacle

varies between 30 V DC and 52 V DC

depending on:

• The length and type of the triaxial cable

• The power consumed by the converter.

The - 5 V is used to delay starting of the con-

verter on camera power on to prevent the

Channel Control Unit power supply tripping

out.

If a DC-to-DC converter (even unloaded) is

connected to the camera while operating, the

safety system will cause the camera to trip

out.

The converter must be connected to the

camera with camera power off.
