CAUTION 
Do not connect GND and SGND to different (external) ground 
references. GND and SGND are internally connected through 
filtering circuitry which can be permanently damaged if subjected 
to voltage drops over 0.8 Vdc. 
 
 
In order to meet EMC requirements: 
• 
connect the reader chassis to the plant earth ground by means of a flat copper 
braid shorter than 100 mm; 
• 
connect the main interface cable shield to pin 1 of the 25-pin connector; 
• 
use two clip-on ferrite sleeves (type Stewart 28A2029-0A0 or equivalent) on the 
main interface cable near the reader 25-pin connector.
