Since the AC 800M units (CPU and communication interfaces) are cooled by selfconvection, it is important that they only be mounted onto a horizontal DIN- rail. Each baseplate has a locking mechanism that contacts the metal backplate to the DIN-rail, providing an effective ground connection. The DIN-rail functions as a very effective ground for the system. The additional screw lugs, located in the lower part of the baseplate, serve no electrical function. They are provided for use should extra fastening be required within environments subject to excessive vibration.

There are two ways of mounting the product in cabinets, open rack or other types of installations; aluminum profile with mounted DIN-rail or DIN-rail mounted on a metal sheet of proper size. The aluminum profile or metal sheet shall be properly connected to protective earth. DIN-rail type with height 7.5 mm shall be used. Refer to type NS 35/7.5 according to standard EN50022. The interference suppression for external signals, are normally directly grounded to chassis and/or plant ground. The plant ground potential must be stable and well defined, even in the event of a low ground fault caused by high voltage equipment or a lightning strike. Each module's conductive back plane connects to the metallic DIN-rail which serves as the module electronics ground conductor between the interconnected devices. This is to ensure a good ground connection both for the internal logic and for the EMI immunity and RF emission of the modules. The DIN mounting rail must have a good bond to the PE of the cabinet. If AC 800M modules are configured as two or more groups interconnected with extension cables, special care should be taken to ensure that the DIN-rails of all groups have a good connection to ground. Also ensure to fix the figure numbers. Mounting on metal sheet The DIN-rail shall be firmly attached to an unpainted metal sheet with fastening screws every 100 mm (4 in) to ensure good mechanical stability and a good chassis ground connection in the cabinet or an open rack. The metal sheet shall at least be 2.5 mm thick and at least 180 mm high. The metal sheet shall be mechanical fastened at least every 500 mm to the cabinet or rack with a minimum of four screws. The fastening to the cabinet frame shall be performed with self-tapping screws to get a good grounding connection.
