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.

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
