2.8.2 Grounding Function 
The grounding function increases the resistance against disturbances from 
electro-magnetic interferences. Some components in the I/O system have a 
carrier rail contact that dissipates electro-magnetic disturbances to the carrier 
rail. 
Fig. 2-24: Carrier rail contact  g0xxx10e 
Attention 
Care must be taken to ensure the direct electrical connection between the 
carrier rail contact and the carrier rail. 
The carrier rail must be grounded. 
For information on carrier rail properties, please see chapter 2.6.3.2.
