1
Connect the external DC power supply to the <DC IN> terminal on the camera.
2
Turn on the <POWER> switch of the external DC power supply (if the external DC power
supply has a <POWER> switch).
3
Confirm that the <DC IN> lamp of the camera turns on.

External DC power supply
Connect after making sure that the output voltage of the external DC power supply is compatible with the rated
voltage of the camera.
Select an output amperage for the external DC power supply with a margin above the total amperage of the
connected devices.
The total amperage of connected devices can be calculated with the following formula.
Total power consumption
÷
voltage
When the power of the camera is turned on, inrush current is generated. An insufficient power supply when
turning on the power may lead to failure. It is recommended to use an external DC power supply that can assure
double the capacity of the total power consumption of the camera and connected devices (such as lens) that
are turned on simultaneously when the power of the camera is turned on. Use AWG18 (nominal cross section of
0.824 mm
2
) or larger double-core shielded cable for the DC cable.
f
Check the pin alignment of the DC output terminal of the external DC power supply and the <DC IN> terminal
on the camera, and make sure to correctly connect the polarity.
Mistakenly connecting the
