Connecting the power cable
Ⅵ ADCTDN2412 (AC24 V or DC12 V)
Connect the AC 24 V or the DC 12 V power cord to the power input terminal.
To prevent connection errors or a cable disconnection, we recommend the
use of lug plates.
The following table shows the connection distances when 2-core VVF
(vinyl-insulated vinyl sheath cables) are used.
Note:
● If thin cables are used, the resistance of the cables will be high and a
significant voltage drop will occur when the camera is at its maximum
power consumption. Either use a thick cable with low resistance or place
the power supply near to the camera and shorten the length of the cable to
restrict the voltage drop at the rated current of camera to below 10 %. If
voltage drop occurs during operation, the performance will be unstable.
● Do not connect an AC 24 V cable to a commercial power supply. The
camera will be damaged. If the wrong cable is connected, the internal
circuit may be damaged. Do not use the camera. Bring it to your nearest
American Dynamics dealer for inspection.
Ⅵ ADCTDN0230P (AC 220 V-240 V)
Connect the power supply cable to the AC 220 V-240 V power supply.
Note:
● When you use this camera, the socket - outlet must be installed near the
equipment to make disconnect on easily.
Video signal coaxial cable
Use either RG-59 or RG-11 coaxial cable (BNC).
Do not use other cables.
