Mounting plate
The mounting plate HD-W is used for equipment receptacles and front plate bushings. This is done by snapping socket KBT.../...-W or plug KST.../...-W (pages 34 37) into the centre hole of the mounting plate. With 4 screws and a special gasket, the mounting plate can be attached watertight to a flat wall, a panel, or a smooth housing wall with suitable hole pattern.
