F.2 Cabling
SF910i can be wired to external devices using standard cables available on the market.
The following tables specifies the technical requirement for the SF910i cables except
SF910i-L.
Note that in this case, ABB does not specify mechanical properties, global cross sections,
fire resistance properties, and so on. The following are the minimum electrical
requirements.
