INSTALLATION Connections to Camera Terminal Board • Turn OFF the power supply to all components before making connections. Remove the terminal board cover by flipping it up while pushing its top to the left. Connections to Terminal Board Remove the terminal board cover and connect 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 control 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 Lug plates DC 12 V or AC 24 V power cable errors or a cable disconnection, we recommend the use of lug plates for the connec- To DC 12 V or AC tions. 24 V power supply The following table shows the connection dis- RX+ C RX- D A TX+ B TX- Control signal cable tances and connection cables provided that To Remote Control Unit (RM-P2580) 2-conductor VVF cables (vinyl-insulated vi- nyl sheath cables) are used.

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: U-type: Class 2 only E-type: Isolated power supply only 15
