CONNECTIONS
A. WV-CL920 (120 V AC 60Hz)
1.Plug the AC power cord (supplied as standard accessory) into the AC Inlet Socket.
2.Connect the AC power cord to a 120 V AC 60 Hz
outlet.
Notes:
•Connect the power cord firmly.
•The power cord should be long enough for pan- ning and tilting.
If the cable is too short, the power cord plug may be pulled off the camera when the camera pans or tilts.

•Calculation of maximum cable length between camera and power supply.
10.8V DC ≤ VA − (R x 0.42 x L) ≤ 16 V DC
L : Cable length (m)
R : Resistance of copper wire (Ω /m)
VA : DC output voltage of power supply unit
L standard = | VA − | 12 | (m) |
