Power supply (DC 12 V or AC 24 V)
Connect the DC 12 V or the AC 24 V power supply to the DC
12V/AC 24V terminals. To prevent connection errors or a cable
disconnection, we recommend the use of lug plates for the con-
nections.
The following table shows the connection distances and con-
nection cables provided that 2-conductor VVF cables (vinyl-in-
sulated vinyl sheath cables) are used.

Conductor diameter
Memo
If thin cables are used (i.e. with a high resistance), a signifi-
cant voltage drop will occur when the unit is at its maximum
power consumption. Either use a thick cable to restrict the
voltage drop at the camera side to below 10%, or place the
power supply near to the camera. If voltage drop occurs dur-
ing operation, the performance will be unstable.
Attach the cable conductors so that they do not come into
contact with the drop prevention wires.
Do not allow input from both a DC 12 V and AC 24 V power
supply at the same time.
When using a DC 12 V power supply, ensure that the polari-
ties of the cable are correct.
The AC 24 V power supply should conform to the following:
U type: Class 2 only
E type: Isolated power supply only
