1. Before mounting a lens, check whether it is CS-mount lens. Dimension (b) of the lens shown in the illustration must be as shown in the table below. If (b) exceeds the value in the table, it may dam- age the inside of the camera or correct mounting may be impos- sible; never use such lenses. The F mark indicates a focal point.

Lens	Flange back (c)	Dimension (b)
CS mount lens	12.5mm	5.5mm or less

*When using the C-mount lens, use the conversion ring (CM46633- 001, MOUNT ADAPTOR).

2.Attach the included ferrite core to the lens cable. Please attach it as close to the camera as possible.

3.Mount the lens on the camera by turning the lens clockwise. Adjust its position.

4.When using an auto-iris lens with an EE amplifier, turn the switch to the “VIDEO” side. When no EE amplifier is equipped, turn the switch to the “DC” side.

5.If the lens has an auto-iris mechanism, connect the lens cable after checking the pin arrangement.

If the lens cable has a different type of plug, use the 4-pin plug. [4-pin plug part no: SCV2859-001]

Contact your dealer of purchase concerning the 4-pin plug.

CONNECTION/INSTALLATION

●Turn off the power supply to all components before making con- nections.

Video signal cable (BNC)

Connect the coaxial cables (BNC) to the VIDEO OUT connector (BNC).

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 discon- nection, 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.

Maximum extension	100 m	260 m	410 m	500 m
(reference)
Conductor diameter	1.0θmm	1.6θmm	2.0θmm	2.6θmm

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 con- tact 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
