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 connections.
The following table shows the connection
distances and connection cables provided
that 2-conductor VVF cables (vinyl-insulated
vinyl sheath cables) are used.

CONNECTION/INSTALLATION

MEMO

• If thin cables are used (i.e. with a high resistance), a significant 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 during 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 polarities of the cable are correct.
• The AC 24 V power supply should conform to the following:

TK-C1480U Class 2 only
TK-C1480E Isolated power supply only

TK-C1481EG (AC230V)

Power supply

TK-C1480U and TK-C1480E (DC 12 V or 24 V)

Power cable connect to the commercial
AC230V outlet

CAUTION:

When you use this camera, the socket-out-
let shall be installed near equipment so
as to disconnect easily.
