Connection Connecting to Power Connect the adaptor to the power input terminal as shown in the figure below. • Output of the adaptor should be either one of AC 24 V, 1.5 A or DC 12 V, 1.0 A. Note that using DC 12 V may cause lower heater temperature. • ---- Power Input Terminal When the resistance value of copper wire is at [20˚C(68˚F)] Copper wire size (AWG) #24(0.22mm2) #22(0.33mm2) #20(0.52mm2) Resistance (Ω/m) 0.078 0.050 0.030 Voltage Drop (V/m) 0.028 0.018 0.011 #18(0.83mm2) 0.018 0.006 • As shown in the table above, voltage decreases as the wire gets longer. Therefore use of • an excessively long adaptor output line for connection to the camera may affect the performance of the camera. * There may be some deviation in voltage drop depending on the type of wire and the manufacturer. Notes • Be sure to connect power only after all the installation is complete. • Note that AC / DC adaptor is not supplied with camera. • Ground should be connected to the GND terminal.
