Hi guys,

Just wondering, can i use some 20 awg wiring to wire the power supply(5a) and cpu(314) together?

i know the power supply  has a bus connector to attach the two together, but i dont have one.

Thanks!

hi, 

see the following manual, chapter 6:

SIMATIC S7-300 CPU 31xC and CPU 31x: Installation

for converting mm² to awg I was searching on google for a converting table.

hope this helps,

regards
