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.
