(11a) Supply Voltage Terminals
This terminal accepts 11-40 VDC or 14-30 VAC at 50Hz (CCIR/PAL) or 60Hz (EIA/NTSC)
power source. The terminals are the quick release type. To connect a cable press the
appropriate release lever and insert the end of cable fully home. Ensure that there is a
sufficient length of bare tinned wire to make contact with the connector. Also ensure that
the cable insulation is not too thick, preventing the cable from being properly inserted.
Only connect the camera to a class 2 power supply.
(11b) Supply Voltage Power Cord
The non-detachable power supply cord must be connected to a power supply of 98 to 260
VAC at 50Hz (CCIR/PAL); or 110 VAC ±10% at 60Hz (EIA/NTSC). CAMERAS MUST BE
CONNECTED TO A PROTECTIVE EARTH GROUND.

This three way connector provides the power and video drive signal for use with video
drive Auto Iris lenses. The terminal block that mates with this connector is provided in the
