4.2.1 Wire sizes
Table1 describes the wire siz es to provide optimal protection against EMI and RFI. Correc t
wires ize is determined by the current requirement and the cable length. The act ual cable type,
wiregauge, s hield type and filtering devices used are dependent on the customer’s application
andsystem. Always useshielded twistedpairs for AC and DC supply cables. For logic wiring
(sees ection 4.3) AWG22 wire is recommended.
