3.3.Preparing Adapter and Cable

-Power Adapter

The SNP-3750/3350 uses an AC24V 2.5A power adapter for the power supply.

Plug the power adapter into a power outlet.

Chart 3-1. Electrical Resistance of Copper Wire at [20° (68°)]
Copper Wire Gauge (AWG)	#24(0.22°)	#22(0.33°)	#20(0.52°)	#18(0.83°)
Resistance (Ω/m)	0.078	0.050	0.030	0.018
Drop Voltage (V/m)	0.028	0.018	0.011	0.06

• As shown in Chart 3-1, voltage drop may occur depending on the length of the copper cable: excessively lengthening the adapter cable may decrease the performance of the camera.

※ Camera Operating Voltage: AC 24V±10%

※ Voltage drop measurements on the chart above may vary depending on the type and manufacture of the copper cable.

- Communications Cable

For the camera to communicate with the controller, a RS-485/422 communications line is required.

Caution

• A 30m or shorter length is recommended for the connection.

* The communication cable is not enclosed with the camera.
