Setup
If thin cables are used, the resistance of the cables will be
Note
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 the AC 24 V cable to commercial power
supply. If it is connected by mistake, the internal circuit may
be damaged. Do not use the camera and make sure to send
it to the nearest JVC dealer for inspection.
Do not connect DC 12 V and AC 24 V cables at the same
time.
When connecting the DC 12 V cables, ensure that the
polarities are correct.
Color of the cables red: +12 V, black: GND
When using a DC 12 V power supply, ensure that the
polarities of the cable are correct.
