When using a VEGALOG 571 with GL approval, 
additional split ferrites must be used to keep the EMC 
regulations. This concerns teh RS232 connection cable 
for the CPU and the Profibus PA cable of the EP card. 
The ferrites are attached to each VEGALOG with GL 
approval and must be mounted by the operator.
