24Installation and WiringChapter 2Notes on Mounting a Camera• Fix the camera securely. You can mount the camera directly or with a designated mounting plate (*insulation type). Referto the dimensional diagram when you mount the camera.When you mount the camera using screws without designated mounting plate, bear in mind that screws comeinto the inside of the camera less than 2.5 mm from its bottom.• The side of the plate mounted is the bottom of capturing images displayed on the screen. The mountingdirection of the camera determines the angle of captured image. Note that it is impossible to rotatecaptured images with the PV310.• To avoid the effect of a variation within mounting dimensional tolerance of CCD element, be sure to verify itwith an actual image.• If the positive terminal of the power supply is connected to ground, be sure to mount the camera in anelectrically insulated way. When connecting between the PV310 and the camera with a camera cable, thecamera case (outer shell) is connected to the internal circuit ground. Therefore, if the camera is directlymounted on the device without insulation, a short-circuit condition occurs between the +24V terminal and0V (GND) terminal, resulting in damaging the internal circuit.Also, even in the case where the negative terminal of the power supply is connected to ground, when youmount the camera on a device with a different electric potential, the parts inside the camera may bedamaged. Be sure to mount it in an electrically insulated way.* From the shipment of May 2007.
