Connecting the power cable
Connecting AC 24 V power
Connect an AC 24 V power cable to AC 24 V power supply.
To prevent connection mistake or cable dislocation, we
recommend the use of a lug board to connect to a AC24V
terminal.
Note
：
●
Do not connect an AC 24 V cable to AC 230 V power
supply. The camera will be damaged.
When using 2-core VVF (Vinyl-insulated vinyl-sheath cable),
the connection distance is as follows: (Reference value)

Note
：
●
To supply AC 24 V, use a AC 24 V supplying power unit
that is insulated from AC 230 V line.
●
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 (when pan,
tilt and zoom operates at the same time). 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 drops during operation, the camera
may experience unstable performance and be unable to
call up the preset position correctly.
●
If the wrong cable is connected, the internal circuit may be
damaged. Do not use the camera. Bring it to your nearest
JVC dealer for inspection.
●
Turn on the power only after the connection for all the
devices is complete.
