Connections to Camera Terminal Board
INSTALLATION
Connections to Terminal Board
Remove the terminal board cover and con-
nect the video signal cable (coaxial cable)
(
× 1).
Connect the DC 12 V or AC 24 V power cables
(
× 2).
In a system where the Remote Control Unit
(RM-P2580), etc. is used, connect the con-
trol signal cables (
× 4).
Ⅲ DC 12 V or AC 24 V power supply cable
Connect the DC 12 V or the AC 24 V power
supply to the DC 12V/AC 24V terminals on
the terminal board. To prevent connection
errors or a cable disconnection, we recom-
mend the use of lug plates for the connec-
tions.
The following table shows the connection dis-
tances and connection cables provided that
2-conductor VVF cables (vinyl-insulated vi-
nyl sheath cables) are used.

• 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 con-
form to the following:
U-type: Class 2 only
E-type: Isolated power supply only
• Turn OFF the power supply to all components before making connections.
CAUTION:
• 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.
