The following table shows the connection distances when 2-core VVF (vinyl-insulated vinyl sheath cables) are used. (Reference value) Conductor diameter (mm) Φ 1.0 and more Φ 1.6 and more Φ 2.0 and more Maximum connection distance: DC 12 V 50 m 140 m 220 m Maximum connection distance: AC 24 V 130 m 350 m 550 m Memo v 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. v Do not connect an AC 24 V cable to a commercial power supply. If it is connected by mistake, the internal circuit may be damaged. Sent the camera to the nearest JVC service center for inspection as the internal circuit may be damaged. 7
