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 damage the inside of the camera or correct mounting
may be impossible; never use such lenses. The F mark indi-
cates 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 at-
tach 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.

Ⅵ 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
