Cautions:
•Be sure to connect the GND (grounding) lead of the camera and grounding termi- nal of the power supply when using a 24 V AC
•Shrinking the
ONLY CONNECT THIS TO 24 V AC or
12 V DC CLASS 2 POWER SUPPLY. (WV-CW484F)
•To prevent fire or electric shock hazard, the UL listed wire
•Do not use a transformer larger than 10 VA.
•Cable Length and Wire Gauge <WV-CW484F>
24 V AC
The recommended cable length and thick- ness are shown in the table for reference. The voltage supplied to the power terminals of the camera should be within 19.5 V AC and 28 V AC.

12 V DC
Use the formula below to calculate the power cable and power supply. The voltage sup- plied to the power terminals of the camera should be within 10.5 V DC and 16 V DC.

10.5V DC ≤ VA - 2(R x I x L) ≤ 16 V DC
L : Cable length (m)
R : Resistance of copper wire (Ω/m)
VA : DC output voltage of power supply unit
I : DC current consumption (A). See specifications.
Important: When using 12 V DC power sup- ply, the optional heater unit is unavail- able.
