CHANGING CAMERA VOLTAGE
Set the camera voltage jumpers for the voltage that the camera will use. Refer to Figure 6 for the locations and settings for the
jumpers.
WARNING: CAMERA DAMAGE POSSIBLE. You will damage your camera if you connect it to the wrong connector on an
EH4700L or EH5700L Series enclosure. If your camera will use the same power as the enclosure, plug the camera into the
CAM1 socket on the circuit board inside the enclosure. If your camera will use 24 VAC and the enclosure will use either 120
VAC or 230 VAC, plug the camera into the CAM2 socket only.
If your camera will use 24 VAC, do NOT plug the camera into the CAM1 socket or you will damage your camera. CAM1 has
either 120 VAC or 230 VAC on it.
BE CAREFUL – REMEMBER – CAM1 IS ENCLOSURE POWER. NEVER PLUG YOUR CAMERA INTO CAM1 IF THE
CAMERA’S VOLTAGE IS DIFFERENT FROM THE ENCLOSURE’S VOLTAGE.
