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;
•
connect the Ethernet interface cable shield to reader chassis (for Matrix-21XX only)
