AD v3 is installed on a control cabinet using a 22 mm (0.87 inch) cable fitting (gland) and a nut. AD v3 is delivered with the cable fitting integrated on the back cover. The position of AD v3 on the cabinet is fixed by the earth ground screw and the nut fastens the device to the cabinet.
AD v3 comes with a rubber gasket for IP 54 preinstalled on the back cover. The rubber gasket is used to help prevent against dust and moisture from entering the control cabinet through the 22 mm (0.87 inch) hole. The rubber gasket also helps prevent the device from rotating when the nut is screwed onto the cable fitting.
AD v3 is delivered with a template to facilitate making a 22 mm (0.87 inch) hole and a 4.5 mm (0.18 inch) hole for the earth ground screw on the cabinet.
When you have installed AD v3 on the control cabinet and fastened the device to the cabinet using the nut, you adjust the position of the device and use the earth ground screw to fix the position. You then connect the earth ground wire to the screw. Finally, you connect the AD v3 cable to the female USB-C connector on the cable fitting. The cable's angled connector helps prevent downward stress of the cable.
